  • The Plastic Extrusion Machine–Process and Methods

    2021-5-21 · PLASTIC EXTRUSION: Plastics extrusion is a continuous high-volume manufacturing process, in which raw plastic is melted and formed into a continuous profile. 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.

    2011-6-28 · The difference between the extrusion and drawing processes lie in the fact that in drawing operation, the metal is forced through the die by compressive forces applied at the entry side. Extrusion is suitable for bar like and tabular objects. Hot extrusion: It is carried out at high temperatures, about 50-70% of the melting point of the metal.

    Abstract. In this chapter we investigate the simulation of aluminum extrusion processes by means of a new heat and fluid flow solver. The extrusion problem is here formulated as two sub-problems, separately solved via a staggered solution strategy, 1) a non-Newtonian Navier-Stokes fluid flow problem where the viscosity depends on both the effective strain rate and the temperature, and 2) a ...
