Ram extrusion is a pressing process that allows the continuous production of profiles. Specially made of UHMW-PE (ultrahigh molecular weight polyethylene). The base material is UHMW-PE powder, which is fed into a cylindrical extrusion tube, compressed by means of a punch and simultaneously transported through the tube, which is heated to sintering temperature. The individual dosing charges sinter together to form a continuous extrudate.
