Manufacturing process in which a softened blank of a metal or plastic material is forced through a shaped metal piece or die to produce a continuous ribbon of the formed product. Use 'extrusion' in a Sentence. We had a factory that was capable of extrusion to create the exact shape and design our marketing manager suggested.
The plastic extrusion process involves melting plastic material, forcing it into a die to shape it into a continuous profile, and then cutting it to length. The process is a good choice for applications that require a final product with a constant cross-section.
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 stresses.
Nov 16, 2017· PLASTIC EXTRUSION: This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted. Mechanical energy generated by turning screws and by heaters arranged along the barrel. The molten polymer is then forced into a die,.
Oct 06, 2019· Plastic extrusion is a manufacturing process through which plastic is melted, shaped into a continuous profile, and cut to length. This process is used in the production of a wide variety of items, including piping, wire insulation, and plastic sheeting. Even adhesive tape and window frames include extrusion as part of their manufacturing processes.
Glossary Knowledge Center. Profile Extrusion Terms. Adiabatic Extrusion – A type of extrusion in which the only source of heat is the conversion of drive energy through the viscous resistance of the plastics mass in the extruder.. Back Pressure – The resistivity of molten plastic material to forward flow.. Barrel – The part of the extruder encasing the screw or plunger.
Extrusion is a continuous process of converting a solid plastic mass, pellet or powder into a melted form where it is pushed through a die into a shape. This shape is then moved through various secondary operations where it is cooled then cut, coiled or experiences a variety of other possible operations.
