Chapter 1: What is Suppository Filling and Sealing Machine?

For the sake of the diverse range of our readers across the globe, we shall begin with the basics so that we can harmonize our flow and discussions.

What is suppository?

A suppository is a new and advanced method of drug delivery into the body.

That is where, the patient or medical practitioner introduces the medication through other body openings such as the rectum, vagina or the urethra.



Suppositories usually come in cone shapes, spheres and mostly small in size.

Whenever it is at the point of intake, it melts and dissolves in the process releasing the medicinal value into the human body.

Suppository administration is an entirely different way from which we usually give conventional drugs through injection, orally, eye and ear drops.

It’s indeed vital to know and be aware of the reasons behind this new concept of medicine intake.

All kinds of medications are usually similar in appearance and structure.

They may be in the form of:

  • Tablets
  • Powder form
  • Liquids, etc

But why the difference in the mode of administration?

Looking at how we take suppositories, it’s apparent that they exist in different varieties.

The most common three types are rectal suppositories, vaginal suppositories, and urethral suppositories.

Different shapes of suppositories

Different shapes of suppository

Therefore, a suppository filling and sealing machine is an automatic state of the art pharmaceutical machine that does three critical jobs in one compartment of machine structure.

Suppository filling and sealing machine

Suppository filling and sealing machine

  • Prepares the base material otherwise known as the shell for the suppositories using the PVC, PVC + PVDC, PE or PVC + PE material
  • Fills the medicinal value into the suppository shell
  • Cools the whole component
  • Cuts them into your designated lengths or sizes
  • Seals the suppository ready for other batching procedures and distributions

Most people prefer referring to suppository filling and sealing machine as a line of production machines or even sets of devices.


It might seem as though that all these functions of shell formation, filling, cooling, sealing and cutting takes place in one set of the machine, right?

Well, that isn’t the case different disjoint sets or units of gadgets drive all these roles.

It would, therefore, be okay to say that all these units make up a production line for a complete and ready to use a suppository.

Now here it is, the whole set of suppository filling and sealing machine comprises of the following four independent subunits:

  1. An initial single Unit that winds two reels of PVC or PVC + PE film, after that, it constructs them into appropriate shapes and sizes of cavities or shells by thermoforming. The ready shells en leave the unit in a continuous strip.
  2. Filler unit that transfers the medicinal mixtures into the cavities strip formed cavities.
  3. Third chiller unit is responsible for the cooling and solidification of the content mix in the molds. Usually, this section got a longer length to provide for an optimum time for cooling.
  4. Ultimate unit which accurately seals off the holes on the batches, prints markings or codes, knurls the strips of suppositories and finally cuts the final products precisely into the desired lengths.

In the next chapter, we shall discuss the avenues of the machine application. Keep on reading.

Chapter 2: Where to Use Suppository Filling and Sealing Machine

The good news about this machine is the diverse and its wide range of applications.

This machine is again technical and very robust in its processes.

For that matter, among its areas of applications are the following:

1. Pharmaceutical industry

The pharmaceutical sector is the primary area where the suppository filling and sealing machine is regularly of value.

The ever cropping and increasingly dynamic range of medicine.

Consequently, pharmaceutical industries globally are fast adopting the use of suppositories as a way of administering vital medications.

No doubt about that, patients continue to testify the swift treatment and remedial action that comes with the use of suppositories.

Furthermore, the suppositories take into account the otherwise beneficial modes of administering medication.

As earlier on discussed, every type of suppository ( rectal, vaginal and urethral) treats several treacherous ailments.

Some common pharmaceutical suppositories are Bisacodyl, hydrocortisone, hydromorphone, etc.

2. Food industry

The suppository making machine is handy when it comes to the application in the food industry.

It’s worth appreciating that suppositories aren’t only meant for medicinal value but also healthy living.

Suppository filling and sealing machine for food industry

The food nutrients, herbal values, and nutraceuticals are the components in the suppositories.

Normally, they substitute the use of pharmaceuticals drugs or reduce the effects associated with them.

Nutrient-filled rectal suppositories are absorbable in the same manner as the medicinal suppositories.

With the aid of the numerous blood vessels in the rectum through the inferior vena cava, the nutrients have got a direct path into the body’s central bloodstream.

Besides, rectal suppositories offer a nontoxic and efficient mode of introduction.

Furthermore, the rectum is buffer free with neutral PH providing an ideal path for nutrient absorption.

The food suppositories deliver highly concentrated nutrients which you cant take through the mouth.

3. Cosmetical industry

The cosmetical industry is also a sector that’s laden with the use of suppository filling and sealing machine in fabricating cosmetical suppositories.

Though controversial, these products exist.

Here area quote from a medical chief in California – suppositories as being drugs or cosmetics depending on the associated claims.

If the products are for cleansing, deodorizing, and external moisturizing only, then they would be classified as cosmetics – “Section ChiefCalifornia Department of Public HealthFood and Drug Branch.”

Mostly, the forms of cosmetical suppositories are Rectal suppositories and vaginal suppositories.

Here, the cosmetical vaginal type suppositories are exceptional for cleansing, deodorizing and moisturizing the body.

These cosmetical types help in maintaining the body support balance, enhancing freshness, and reducing strong feminine odor.

Likewise, rectal glycerin suppositories help in averting occasional constipation.

Those are the three areas you can comfortably use the suppository filler and sealer.

Next, we focus on the advantages associated with the use of the device.

Chapter 3: Benefits of Suppository Filling and Sealing Machine

The whole production system has got enormous benefits.

This is not only on the production of complete and ready to use suppositories but also other procedural advantages.

Indeed, it is due to the advancement and several modifications that manufacturers continuously incorporate in this machine.

Remember, the food, cosmetical, pharmaceutical, and health care industries all benefits from the services associated with this machine.

vi. Adequate capacity of fluid reserve/capacity

Most of these machines have got a large capacity storage tank for the fluids.

The bigger storage tank would save you the energy and stress of having to refill the vessel regularly whenever the content gets exhausted.

With this size of the tank, you can comfortably keep up to 80L of the content for discharge. That sounds perfect.

vii. Requires Less supervision

With this kind of sophisticated equipment do you mind regularly supervising the production? No, you don’t.

All the procedures here are automatic with the help of the PLC.

With this kind of programming, you only need to key in the parameters required then you sit back and relax as you wait for the production to complete.

viii. The suppository filling and sealing machine occupies reasonable floor space

Most readers always imagine the production system to be very complicated.

On the contrary, the whole set of compartment only occupies a sizeable floor space.

Portable suppository machine

Portable suppository machine

Think of performing all these operations with a set of the machine that only occupies 3.470 * 3.480 * 2.230 m of your working area.

Isn’t that reasonably small?

Besides, to adequately cater for all the movement and operations around the machine, you will only to spare about 1 meter of the space.

That’s it.

ix. Regulated cooling speed system

Different drugs would undoubtedly require a contrasted speed of cooling.

Some take a long time while others take a very short duration to solidify.

Suppository system

Suppository system

This difference in cooling rate inevitably calls for the need to regulate the cooldown.

Flexibility in speed is what you get when using this machinery.

The temperature regulator ensures that the contents solidify uniformly and appropriately.

x. Required certification

You don’t need to worry about acquiring various operational certificates and filling much paperwork.

You shall get all the necessary documentation intact.



The suppository filling and sealing machine is well certified by various organizations and quality control bodies.

Some of the certifications implied here are CGMP, CE, FDA, CPGP, ISO and many more.

xi. No wastage of materials

We are dealing with a highly optimized machine here.

Thus, you would be surprised to note that the suppository filling and sealing machinery doesn’t give any chance to wastage of materials particularly during the operation.



Whatsmore, in case of any power cut or mechanical breakdown during the working process, you would incur any material waste.

Other notable advantages associated with this system are:

  • Flexible cutting gains speed adjustment capability.
  • It can operate with different types of material structure for making the suppositories, ie. PVC, PVC + PE, PE
  • Possibility in regulating the speed of the mixing tub. The industrial mixing motor ensures that it mixes all the ingredients of the contents homogenously.
  • The machinery parts are stainless steel eliminating any chances of rusting and corrosion that might make it.

The end products of the suppository filling and sealing machines are essential as well.

Here are a few reasons why people opt for suppositories.

a. It’s an alternative admission of the drugs that can’t pass orally.

The earlier and favorite technique of medicine admission was oral.

However, some medications can’t just pass in this manner.


Some are very difficult to swallow because of being nasty and unpleasant to the mouth.

For that matter, suppositories come in hand to rescue the situation.

b. Suppositories make it okay to take medication which is difficult for the stomach absorption.

You notice that the stomach doesn’t readily absorb other medications probably due to their high resistance to dissolution.

For that sake, suppositories are helpful since they easily release the drug.

It doesn’t necessarily have to pass via the stomach since the whole content pass through the bloodstream.

c. They have got a quicker impact on

Remember, the suppositories work in a straight forward manner, all they undergo through is melting and release of contents directly into the bloodstream.

As a result, they take only a short period to reach the target body section thereby achieving its therapeutic effect.

In other cases, the suppositories treat the region in which you place them.

For example, they are a functional cure for allergies, fever, pain, bacteria/ fungal infections, hemorrhoids, etc.

Moreover, suppositories are useful for patients who may suffer from the following conditions.

  • constant vomiting whenever taking medicines.
  • In case drug would easily dissolve very fast within the gut.
  • If the drug would lose its medicinal value when passing through the gastrointestinal channel.

Don’t you think that suppository filling and sealing machine is must-have equipment?
let’s move onto the next segment.

Chapter 4: Types of Suppository Filling and Sealing Machine

Suppository filling and sealing machine come in many shapes and designs.

The design depends on the specific applications requirements.

In a nutshell, before making a quote, the ultimate question you need to ask yourself is:

What’s my suppository target type?

In this segment, we shall discuss all the three major types of suppository filling and sealing machines.

You will find it helpful.

You need to note that these machines aren’t anywhere different from each other by operation, structure, and modification.

Types of suppository machine

Type of suppository machine

The three types of machinery are:

  • Vaginal suppository filling and sealing machine
  • urethral suppository filling and sealing machine
  • Rectal suppository filling and sealing machine

We shall now look at each in details.

1. Vaginal Suppository Filling and Sealing Machine

The vaginal suppository filling and sealing machine produces vaginal suppositories.

Normally, the device formulates this brand of suppository in solid and oval shape.

You don’t have to be worried about their hard nature.

When in use, they melt into a liquid whenever they’re inside the vagina due to the warmth from the body temperature.

A plastic applicator enhances the application of the suppository into the vagina.

Vaginal suppositories provide relief from vaginal related disorders and infections.

Why use vaginal suppository?

  • Vaginal suppository especially the contraceptive ones help in birth control.
  • They also help in curing the fungal infections such as vaginal candidiasis which is a common vaginal yeast illness.
  • To maintain proper vaginal moisture and optimum PH aiding in preventing dryness.

Remember that whenever you use this kind of machinery, the parameters you input should be of those of the vaginal suppositories.

2. Urethral Suppository Filling and Sealing Machine

Similar to the previous machine, this brand also does a sole job of producing urethral suppositories.

The conventional urethral suppository is MUSE which is small in size usually a grain size.

Specifically, it’s dimensions are the 1.4mm diameter and 3mm to 6mm in length.

The machine fills the shells with alprostadil which is an erectile dysfunction medication.

Alprostadil works by relaxing the smooth penis muscles making more blood to flow to the penis hence achieving an erection.

Furthermore, machine designs the suppositories in three distinct forms: 250 µg, 500 µg, and 1000 µg.

The prescription of each size relies on the recommendation by the doctors or qualified personnel after supervision.

3. Rectal Suppository Filling and Sealing Machine

Rectal suppository machinery is an elite category for constructing only the rectal suppositories.

It is very flexible in its operation and produces the suppositories in a round shape with the tip having the form of a bullet.

Normally, the molds from which the suppository shells come from taking care of the design structure.

The sizes of the rectal suppositories are 1 inch long.

Remember the most common rectal suppositories are Therevac, Dulcolax and Magic bullet.

So why are rectal suppositories filling and sealing machines important?

The rectal suppositories do the following:

  • To administer medication such as antibiotics, analgesia, respiratory treatments, and sedation, etc.
  • To treat anal hemorrhoids or anal pruritus referred to as itching.
  • To prevent constipation

Those are the three types of Suppository filling and sealing machines available.

Next, we tackle another vital segment of our discussion.

Chapter 5: Parts of The Suppository Filling and Sealing Machine

It’s indeed a common trend for such a state of the art machine to have several parts.

These parts are vital in collaborating for the whole and general working mechanisms of the machinery.

Meaning that you cant achieve your final viable target without incorporating any one of the segments.

It, therefore, calls for maximum care and regular inspection of the parts to ascertain their smooth operations.

Other auxiliary devices are also essential in aiding the operation of this machinery.

Suppository filling and sealing machine parts

Suppository filling and sealing machine parts

These are the major components of the suppository filling and sealing machine you shall encounter.

  • Film Unwind and Feeding Part
  • Molding/forming section
  • Filling Part
  • Cooling tank segment
  • Closing and sealing section
  • Fully automatic packing machine
  • Electrical control system

We now discuss all these portions into details.

· Film Unwind and Feeding Part

Film unwinds, and feeding part forms the first unit of the machinery.

The first unit forms the basis of the entry of the raw materials required for conducting the whole operation.

As we earlier noted, the film unwinds in two strips.

Additionally, the films that we use here may be of the three types according to your preferences and availability, i.e., PVC, PE, PVC + PE.

The film unwinds part consists of the film release plate and transfer fixture.

The plate is the initial area where you place the film.

The transmitting fixture or the clamp would act as a trolley for relaying the film.

This area is known as the feeding part since it is the initial entry point for the film that forms the necessary component for creating the molds.

· Molding/ Forming Part

This the actual area where the suppository shells are forming, or molding occurs.

This part comprises a guide wheel which rolls the packaging compound to the forming area.

In the forming station are the heating mold situated in the first clamp spot — the pre-heating cavity located in the second clamp place forming shapes occupying the third clamp position.

Also, you will notice the corresponding blowing molds known as butt molds in the slots perpendicular to the forming cavity.

All these molds are responsible for making the shells of the suppositories through a shaping process.

Some other devices which also helps in the shaping and cutting of the shells found at this station are base finishing and dotted line cutting equipment.

This equipment produces a good shell.

· Filling part

This section has got several operations going on together with various devices that operate here.

Some of the devices that comprise the filling parts include the filling pump, a large capacity material bucket, agitator, stirrer and circulating pump.

Filling pump drives in the materials mechanically with the use of some force into the material bucket.

The filling pumps work is even made much easier by the several plunger pumps attached to it together with about ten material injectors found at the bottom of the siphon.

Normally, the material buckets serve as a temporary storage facility for the material and its at this point that homogenous mixing occurs.

All these gadgets enhance the filling procedure.

Corresponding sandwich layers of hot water heat the materials in the bucket to your set temperature limit.

An additional electric heater gets incorporated in raising the temperature until up to about 80 °C.

Also, the agitators in the bucket are motor driven, together with a variable speed stirrer.

A recirculation pump helps in distributing heat and maintaining a homogenous temperature of the material.

Now, the circulation pump also aids in maintaining the continuous circulation and supply of the materials between the filling pump and the material barrel.

The filling part is equally the point where the molds get filled with the materials.

· Cooling tank segment

Double cooling tunnels, air cooler fans, and water chillers are the component devices you find here.

The two cooling tunnels provide a large surface area for sufficient cooling to take place.

It’s also large to keep the suppositories for a longer and adequate cooling time.

The suppository strips enter into the cooling tunnels for a cool down.

Here, the water chillers are responsible for supplying low temperature which is afterward distributed by more cooling fans.

All these factors work together to ensure that the temperature at this zone maintains at about 8 °C to 16 °C.

· Closing and sealing stage

The sealing tail passes the cooled suppositories in strips to the mold preheating for another re-heating of the suppositories.

Another pneumatic sealing box element then seals the suppositories tails.

· Marking and printing part

An inkjet printer does the work of publishing four lines on every strip set of suppositories.

You may customize the marks made here according to your preferences.

However, the characteristic markings are the batch number, expiry date, manufacturer, date of manufacture, and batch number.

· Trimming and cutting element

The suppository strips pass into a sharp cutting element where trimming of their top edges takes place.

Finally, the sharp blades cut the suppository.

Remember, a fully automated cartooning machine does the job of packing the suppositories into packets.

· Electrical control system and cabinet

A critical segment is the electrical control system where all the power control and electronic supply regulation to the machine originates.

The following are Some of the gadgets in the electrical and control cabinet;

  • PLC communication module – responsible for relaying and synchronizing all the programmable information and data into the operation of the machine.

  • Human-computer interface. The human-computer interface comprises of various input and output electrical devices for example graphics, voice – input and touch-sensitive gadgets.

All of these devices work in harmony between you the user and the computer which in turn disintegrates the information into the working mechanism of the machinery.

  • Sensors and transducers – some essential types of transducers in use here are the ultrasonic, temperature, piezoelectric and pressure transducers.

In summary, the transducers convert and manipulate different categories of energies including electrical energy, light energy, mechanical energy, chemical energy, thermal energy, acoustic energy, electromagnetic energy, and others.

  • Sensors
  • Thermoregulator and thermoforming devices
  • Electromagnetic valve air processing equipment
  • Warning electrical device
  • An auto electronic switch, approach with or limit switch.
  • Siemens component mostly PLC + HMI
  • Control panel and display

Other optional spare parts for the machine include:

  • Suppository mold
  • Air joint, bearings, belts
  • Dotted cutters
  • Sealing rings, cables
  • Resistance heating rods

The discussed elements make up the subunits of the machinery.

About the respective weights of the subunits, each has got different weights depending on the quantity of the components in them.

The formation and the filler units together have a weight of 10000N.

Normally, the cooling unit has 4000N while the other completion segments weigh 6000N.

These weights vary from one machine to another depending on the manufacturer.

There you go those are the critical portions of our device.

You notice that we never included some other minor segments, but they also do play an important role.

Chapter 6: How Suppository Sealing and Filling Machine Works

Under this segment of our discussion, I will take you through the complete working mechanism of the suppository filler.

Please note that we shall try to make this procedure as practical as possible so that you may get to understand it fully.

Shall we begin?

Film unwind stage

You may choose whether to use a PVC or PE film material. Ones you decide then its time to make the machine running.

The PVC/ PE/ PVC + PE moves from the film unwind in the plate and passes through the transfer structure by the action of the clamp.

The clamp structure here relays the PVC into the molding section.

Molding and formation section

The continuous film strips then enter into the molding station through the guide wheels.

In the forming station, the material passes through several segments of formation molds such as:

  • Pre-heating
  • Heating
  • Forming
  • Blowing casts

Here, the substance now assumes the desired shell cavity with a suitable shape for holding suppository content.

After that, the formed shapes get to be precisely cut by the action of a triangle side knife and dotted line cutting blades.

Meanwhile, the shaping processing gets underway on the bottom margin of the cavities.

All these activities still happen in the formation stage before releasing the entirely shaped shells into the next step.

Filling step

The already homogenously heated material at about the temperature of 80 °C is ready for filling into the shells.

Remember, the filling station has got three to six filling terminals.

The ready suppositories strips get loaded at once then relayed to move on.

Usually, the dosage of each suppository is 1 gm to about 5 gm with an acceptable error of ±0.2.

Because this machine is fully automated, the accuracy of the filling should be about ± 1%.

You don’t have to worry about the rest of the raw material. An electrical heater keeps it continuously heated at an appropriate temperature.

The mixing motor also keeps on mixing the raw material to achieve a homogenous mixture.

Subsequently, the raw material from the injector carrier enters into the filling terminal via a nearby circulator.

While the remaining portions of the material recirculate into the tub for the next round of filling.

The whole set of suppository strips proceeds to the next stage.

Cooling step

The whole strips of suppositories gain entry into the cooling tunnel.

Mostly, the temperature at this area gets moderated by the double cooling units, air coolers, icy water from the water chillers and the cooling fans.

In the tunnel, the cold water and the cooling air from the quadruple condensers ensure that the suppositories cool down sufficiently.

For the suppositories to appropriately cool and solidify, the temperature here is always in the range of 8 °C to 16 °C.

Sealing process

Afterward, the cooled suppositories proceed into the sealing tails.

This system relays the suppositories into the preheating mold for another sequence of reheating.

After that, a pneumatic sealing element embeds a seal on each suppository.

Printing procedure

After sealing, the relay strips transfer the sealed suppositories via the ink jet printer for printing.

The products get some print codes which may include:

  • Batch number
  • Date of manufacture
  • Manufacturer, etc.

From the printing machine as they pass continuously to another station.

Cutting segment

The almost ready product now have to pass in between a pair of sharp blades for cutting.

A group of six suppositories gets cut from the strip.

Depending on your preference you can flexibly adjust the number of grains you need to cut to more or less.

The only thing you need to do is to key in the command from the control panel.


The cut row drops into a cartooning machine which in turn places the suppositories into packets at a higher speed approximately 40 packs per minute.

Once filled, the packing device then closes the packages.

Finally, you would pick your finished and nicely packed suppositories.

That’s it, a very straightforward process.

You should realize that all these processes, i.e., forming, filling, cooling, sealing, cutting, printing and packing we discussed above follows a synchronized system.

Above all, you must ensure you adhere to safety and control measures when running the production.

Coupled with this working mechanisms are the substantially significant modes of operation of this machine that you have to be conversant with during production.

These modes of the operation are critical in helping you to explore various avenues of running your production.

Besides, you get freedom of manipulating and shifting from one course of the process of running the machine to another.

Of course with ease depending on your production needs and circumstances.

Thus these modes are ;

  • Reset
  • Automatic
  • Manual
  • Emptying

Let’s have a brief discussion about each.

Section of automated system

Section of automated system


Before presenting, it’s essential for you to verify whether every part of the machine is in its original position.

Actually this the same requirement for quick starting.

Why would you reset the operation?

Because it’s a necessary measure that you have to undertake after the working of the molding die either in manual or semi or automatic mode.

To perform a reset, do this:

  • Confirm if the machine is correctly connected, ensuring that all the power and signal cables are rightly plugged in.
  • Now switch on the main power button.
  • Set the Manual or Automatic switch to “Manual.”
  • Finally, dial the reset knob. There you go.

  • If appropriately connected, switch on the power button.
  • Carefully and appropriately install the roller
  • Now, press the reset knob.
  • After that, press the start button

· Manual

This a pretty direct one, on the touch screen panel, click the “manual” command.

A new prompt opens displaying a submenu.

Again, click any function key to begin the operation.

· Emptying

This effective procedure does the role of draining the coolant strip located in the tunnel of all the suppositories.

You may perform emptying to bring the operation to an end.

Meanwhile, the formation and filling stations would stop whenever you empty.

Therefore, the guide wheel quickly transfers all the suppositories from the cooling tunnel through the sealing part and cutting blades until they are exhausted.

Here is the way we should perform the emptying task.

  • First of all check and verify in case the machine is rightly connected.
  • Turn on the main button.
  • Set the manual/ automatic switch to “Manual.”
  • Press the reset knob
  • Set the manual/ automatic switch to “Automatic.”
  • On the touch screen panel, click “empty” to begin.

Chapter 7: Installing Suppository Filling and Sealing Machine

How do I install the machine?

Do I require the services of a technician to install?

How much floor space do I need?

These are just a few of the several questions regularly asked by many users.

Luckily, we have all the answers to these questions and many more.

We have simplified all these guidelines under the different relevant segments or factors about installation.

Installation of any machine is vital in initiating and maintaining the correct working.

The inappropriate connection may make the gadget to malfunction.

In some extreme cases of wrongful installation, the device might end up breaking down.

You thus need to be careful and cautious when installing the device and strictly adhere to the set guidelines of your manufacturer.

Here is all that you should do.

Ground installation

Your space area should be free from any excessive vibration.

Apart from that, the machine has no other specific unique requirements or conditions for making the ground support.

Above all, you have to level the framework for your installation using appropriate hand tools.

Always tune the machine anchor bolts for you to make the connection of all the parts uniform and appropriately.


As we earlier mentioned, the suppository filler and sealer has got five disjoint parts which you have to assemble and connect properly correctly.

Remember that although these parts operate independently, you have to interconnect them to achieve a viable product.

  • To kick off, connect the filling station with a single end of the cooling tunnel.
  • When through, connect the sealing part with the other opposite end of the cooling station. Make sure you flush all your connection parts to achieve a firm grip.
  • It’s time now for you to install the material barrel appropriately.
  • Finally, connect the chiller with the cooling station.

Installing the power connections

under this section, we shall discuss the electrical and pneumatic connections.

  • Electrical connections
  • First, locate the electrical box.
  • Then take the electrical cable and attach it on the aviation plug. You shall find the aviation plug at the back of the electrical box.
  • Make the three-phase electrical connection in order.
  • Now regulate the power supply voltage and the working frequency as stipulated in the manual.

Pneumatic connection

  • Begin by opening the door, after that, fix the compressed air connector together with the air connector situated in the forming frame. Note that the diameter of the connecting pipe you use should be of minimum 14 mm.
  • Maintain the air pressure at 0.6 mph to 0.7 mph. You achieve the correct air pressure by correctly tuning the pressure gauge valve until it indicates your preferred value.

Dealing with supplementary equipment

The suppository is filling and sealing machine come with other associated equipment such as chillers.

For the sake of our guide, we focus on the chillers which have a significant function of cooling the tunnels.

  • Fix the chiller with the cooling shaft using two circulation pipes. One pipe meant to coll the water while the other one for heating the water.
  • Afterward, Connect the outlet pipe and the inlet pipe of the chiller and the cooling shaft respectively.
  • Finally, connect the return pipe and the inlet pipe of the cooling shaft and the chiller respectively.

That’s all about the installation. So you have all the information you require to do this.

Do you often experience problems when working with your machine?

The next section solely for you.

Keep on reading.

Chapter 8: How to Troubleshoot Suppository Filling and Sealing Machine

Well, errors are a common thing when it comes to electronics and electrical devices.

It’s indeed very reasonable for this kind of mistakes and faults to happen with any other machine.

Suppository filling and sealing device isn’t an exception.

The technicians attribute these faults to the type and level of technology applied to build the gadget.

Even though this machinery is fully automatic and uses a sophisticated PLC programme, many users across the globe still bump into several issues during operation.

The two common types of errors that you may often experience are system errors and mechanical errors.

Remember, the only prompt and first-hand solution to these ever arising problems are troubleshooting.

Chapter 9: Technological Advancement in Suppository Filling and Sealing

Contrary to what you might think, the technological advancement and input in this machine are just mind-boggling.

Mighty works and configurations incorporated here are unmeasurable.

From the control, additional devices and the general operations, it’s fantastic. We shall look at that.

· Operation interface/touch screen

The user-friendly touch screen in this device will amaze you.

It’s free from regular crushes and very sensitive to touch.

It responds at the touch of command, so you don’t have to press or apply any unnecessary pressure continuously.

Besides, the touch screen displays all relevant information and input commands that you require such as the various parameter settings, e.g.

  • Pressure
  • Temperature
  • Manual/ automatic operation modes, etc.

With the use of the touch sensitive type induction switch, your options for running the machine are endless.

You can freely manipulate the input parameters such as the production speeds.

Apart from that, you can work out tiny changes and have full access to all the settings of the operation of the machine.

· Sensors and photocells

The sensors, photocells and optical fibers in the machines are responsible for placing in check the operation of all the power logic.

With the use of a connection device, both the sensors and photocells transmit information by depending mostly on the feedback.

This feedback comes from the operation of the system as opposed to that of the contact proximity sensing ability.

For adoption of their work, these sensors and photocells use the attached induction lamps.

So for you to diagnose it, you need to loosen or tighten the bolt appropriately to tweak its position.

Note that, it shouldn’t be too far or too close.

You thus need to correctly set and select all the sensors and photocells since they would significantly determine the state of operation of the machines.

Above all, you have to regularly clean and inspect these components to assess their conditions.

· Thermostat

The thermostat here regulates the temperature of the machinery during operation.

To carry out this, you can perform the relevant thermostat settings from the touch interface.

The thermostat prompts an alarm whenever the temperature of the operation is above that set by the user. Often you will hear two types of signals, i.e.

  • One that goes when the temperature falls lower than the set temperature
  • Another for a higher temperature than the set quantity
