Film Heating

An unwinding clamp will transfer the film strip to the shell formation stage

Shell Forming

As the film strips reach this stage, they will undergo molding and formation.

The film strip undergoes preheating, forming, and blowing to form the cavity where you will fill suppositories.

Suppository Filling

In this stage, you fill the shell cavities with a homogeneous mixture, which is at 80 °C.

The filling valves are accurate allowing an error of +/- 0.1 grams.

Mixers will continue mixing the mixture while the heater maintains the optimum temperature.


Cutting blades will slice the shapes of the suppositories to the precise shapes.

Cooling Stage

The cooling chamber provides a low temperature to cool the suppositories in the shells.

This enables the homogeneous mixture to solidify before moving to the next stage.

Shell Sealing

A sealing system will use pneumatic systems to reheat and seal the shells appropriately.

Trimming and Cutting

The suppository machine will cut the suppositories once again in the correct size and shape.

Finally, the suppositories go to the packaging stage.
