- 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
- EXTRUSION: Orientation: The Good and the Bad | Plastics Technology
Orientation occurs in every extrusion process due to the inherent strain applied to the long-chain molecules as the polymer is shaped and flows through the die Some orientation through the die is unavoidable, and the magnitude depends on output rate for a given die design
- 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
