- Plastics Extrusion | Plastics Technology
Extrusion is a continuous process through which parts of a fixed cross-sectional profile are made Material is fed through a hopper into an extruder, essentially a rotating screw surrounded by a heated barrel, where it is mixed, melted and pumped through a die The die gives the part its shape Types include film extrusion, sheet extrusion, pipe, profile and tubing extrusion
- Film Extrusion | Plastics Technology
Film extrusion is divided into two subcategories: cast film (flat film) and blown film In cast film extrusion, hot plastic is extruded through a flat, slit die onto a polished chill roll where it is quenched, pulled to a second set of rolls to cool the other side, then wound In blown film extrusion, plastic is extruded into a cylindrical die, then inflated to form a bubble, which is cooled
- Pipe, Profile and Tubing Extrusion | Plastics Technology
Pipe is formed when plastics is extruded through a round shaping die, cooled in a water bath, and either cut and coiled Used in manufacture of medical tubing; PVC pipe; HDPE pipe; siding; plastic decking; plastic fencing; window lineals

That is THE question that plastics processing managers everywhere are asking And they have been asking it for a while now The skilled labor shortage is a real problem facing the plastics industry If you are having a difficult time finding skilled employees, you have alternatives One of the best is freeing your company from
- Sheet Extrusion Line | Plastics Technology
A sheet extrusion line consists of an Extruder (single or twin screw), equipped with a Screen Changer and a Gear Pump, followed by a Static Mixer (sometimes feeding a Coextrusion Feedblock that is preceded by one or more additional extruders sets as described above), feeding a flat sheet die
