During the extrusion process, plastic in the form of pellets or powders is fed into a heater barrel where rotating screws homogenize and squeeze it through a die to form a finished or semi-finished product.

Injection Moulding

In injection moulding, the plastic is forced into a mould at very high pressure. The mould is kept at a given temperature while polymer solidifies. The two halves are then opened and the finished product is ejected.

Blow Moulding

In the blow moulding process, a molten matrix is extruded in the form of a vertical tube (parison), which is clamped between two halves of a mould. This tube is inflated with air so that it takes the shape of the mould. It is then cooled and released as a fully formed product.


Thermo-forming is the general term used for the process of making plastic parts from a sheet of plastic through a combination of air pressure and temperature change. In it's most sophisticated form, thermo-forming can provide the precise properties and sharp detail required to meet very stringent specifications.


Blown Film

This is the most common way of manufacturing film. A plastic blend is fed into an extruder where it is melted and homogenized before being pumped through a circular blown film die. The melted plastic forms a continuous tube which is drawn from the die. It is inflated and simultaneously cooled with fast moving air, allowing the plastic to solidify quickly. The tube is then collapsed between rollers and wound onto a reel.
