  • The Plastic Extrusion Machine–Process and Methods

    2021-5-4 · Plastic extrusion, also known as plasticating extrusion, is a continuous high volume manufacturing process in which a thermoplastic material -- in a form of powder, pellets or granulates -- is homogeneously melted and then forced out of the shaping die by means of pressure. In screw extrusion, the pressure comes from the screw rotation against ...

  • Custom Plastic Extrusion Services | PEXCO

    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 …
