9. How does Suppository Filling and Sealing Machine Work?

The suppository filling and sealing machine works through the following stages:

· Stage One: Film Unwind Stage

At this point, you will choose the type of materials that you will use such as PVC or PE materials.

Depending on the film material that you choose, the film moves from the unwind plate through the transfer structure.

With the help of a clamp the film unwind will relay the PVC to the molding section of the machine.

· Stage Two: Molding and Formation

The film will go through several sections of the molding and formation stages.

The stages include preheating of the film, heating, forming and blowing casts.

At this point the shells will assume the desirable shape of the suppositories.

With the help of dotted line cutting blades and triangle side knives, the machine will cut the shapes precisely.

· Stage Three: Filling Step

After the formation of the shells, you will fill the homogenous materials which is ready at 80 degrees centigrade.

The machine will load the empty suppositories to the three to six filling terminals.

The dosage on every suppository ranges between 1 gm to 5 gm depending on the dosage requirements.

It allows a margin of error of plus or minus 0.2 grams.

The efficiency an accuracy of the machine allows an error of plus or minus 0.1.

As this happens the heaters maintain the heat as the mixers continue with the mixing procedure of the content.

All the remaining portions recirculate the system until it receives the proper amount of fills.

· Stage Four: Cooling

At this stage, the machine regulates the temperature using the double cooling units, water chillers and air coolers.

In the cooling tunnel, the suppositories cool down completely through the assistance of the cooling apparatus.

Remember to maintain the cooling temperatures between 8 to 16 degrees centigrade for an efficient cooling process.

· Stage Five: Sealing

The sealing of the suppositories is possible through the sealing tails.

At this stage, another sequence of reheating occurs after which a pneumatic system embeds a seal on every element.

· Stage Six: Printing Stage

This is the part where the ink jet printer will print the manufacturing and expiry dates, and the batch number.

· Stage Seven: Cutting and Packaging

With the help of sharp cutting blades, the machine will cut the suppositories accordingly.

You can program the machine to cut the number of suppositories at a particular speed.

It then proceeds to the cartoning machine which places the suppositories into the right packets.

It completes the process by closing the packages completely for storage and distribution purposes.
