Extrusion is a process used to create objects of a fixed cross-sectional profile A material is pushed through a die of the desired cross-section The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections, and to work materials that are brittle, because the material only encounters compressive and shear stress
The Extrusion Process 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 ,
