Extrusion is a manufacturing process used to create long objects of a fixed cross-sectional profile.
A material is pushed and/or drawn through a die of the desired profile shape.
Hollow sections are usually extruded by placing a pin or piercing mandrel inside of the die, and in some cases positive pressure is applied to the internal cavities through the pin. Extrusion may be continuous (producing indefinitely long material) or semi-continuous (producing many short pieces). Some materials arehot drawn while others may be cold drawn.
The feedstock may be forced through the die by various methods.
A single or twin screw auger, powered by an electric motor, or a ram, driven by hydraulic pressure), oil pressure, or in other specialized processes such as rollers inside a perforated drum for the production of many simultaneous streams of material.
Extrusion simulation tools help to understand the extrusion process and to optimize development of tools and product.
Commonly extruded materials include metals, polymers, ceramics, and foodstuffs. We will show extrusion of plastic material.
Plastic Extrusion:
Plastics extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile.
Extrusion produces items such as pipe/tubing, weather stripping, window frames, plastic sheeting and wire insulation.
Plastic extrusion commonly uses plastic chips or pellets, which are usually dried in a hopper before going to the feed screw.
The polymer resin is heated to molten state by a combination of heating elements and shear heating from the extrusion screw.
The screw forces the resin through a die, forming the resin into the desired shape. The extrudate is cooled and solidified as it is pulled through the die or water tank.
A multitude of polymers are used in the production of plastic tubing pipes, rods, rails, seals, and sheets or films.
