Plastic Extrusion Resources › What is the Process of  Plastic Extrusion?

The process of plastic profile extrusion is the process of making continuous shapes of plastic (not including sheets and tubes) by extrusion.

Raw plastic beads are melted, shaped into a continuous profile, and cut to length. This process produces a wide variety of shapes and plastic channels.


More specifically, the raw plastic beads or pellets are mixed with colorants before the plastic profile extrusion process begins. Once inside the machine, the plastic beads and any accompanying material move through an opening in the extruder cavity toward a screw mechanism. The rotating screw forces the plastic material through the cavity.


Inside the cavity, the temperature is very high, often reaching about 400°F (200°C), which melts the plastic. When the molten plastic reaches the front of the cavity, it moves away from the screw and journeys through a special screen designed to filter out any contaminants. Then the molten plastic moves into and through a die which is responsible for giving the molten plastic its profile (shape). After cooling, the product is cut to length, spooled, or coiled and produces a distinctive plastic channel, profile or tube.

Jifram extruded plastic profiles. Plastic Profile Extrusion is a manufacturing process through which plastic is melted, shaped into a continuous profile, and cut to length. This process is used in the production of a wide variety of shapes and channels.
In this process, raw plastic is fed into a heated extruder cavity or cylinder. Typically, the raw plastic is in bead form and may be mixed with colorants before the plastic profile extrusion process begins.
