EXTRUSION OF THERMOPLASTICS MATERIAL |
摘要 |
For the continuous extrusion of thermoplastics material and in particular ultra-high molecular weight polymer material, the material is drawn by frictional drag along a passage between a groove (13) in a rotatable wheel (11) and a stationary overlying shoe member (14). An abutment member (15) having an associated extrusion die (16) at the end of the passage is provided with heating means (21) to maintain the temperature of the material being extruded at selected temperatures, preferably above the melting point of the material. |
