Processing Plastic-Extrusion

The Extrusion Process:

Many geometrical shapes are possible when using the extrusion process.  The most common product form is thin film, either flat or tubular. Other extruded products include pipe and tubing, coated paper or foil, monofilaments and textile fibers, flat sheet (anything over 0.010 inch (0.25 mm)), wire and cable covering, and a great variety of profiles such as window frames, gaskets, channels and house siding. The products can be cut to length or rolled up as needed.

In the plastics extrusion process, raw thermoplastic material, or resin, is gravity fed from a top mounted hopper into the barrel of an extruder. Additives, such as colorants and UV inhibitors, in either liquid or pellet form are often used and can be introduced into the resin below arriving at the hopper. The process has much in common with plastics injection molding though differs in that the process is usually continual. While injection molding can offer many similar profiles in continuous lengths, usually with added reinforcing, the finished product is pulled out of a die instead of extruding the fluid resin through a die.
