Solid face die plate

摘要

A solid face die plate for an underwater pelletizer includes a carrier or holding plate having a circular slot for holding a hard anti-wear element of highly wear-resistant material through which the extrusion orifices open for extruding polymer. The solid face die plate eliminates the need for insulation or plugging material in the center of the die plate and, by embedding the hard anti-wear element within the carrier, protects the edges of the hard anti-wear element for longer wear life.

1. A solid face die plate for extruding polymer in an underwater pelletizer comprising:
a solid face die plate having a die plate body with a generally circular, solid downstream face and a generally circular solid face plate affixed to an attaching surface on the solid downstream face of said die plate body and extending fully across said solid downstream face, said solid face plate including a carrier and a hard anti-wear element embedded within said carrier, said anti-wear element being made of tungsten carbide and said carrier being made of a nickel-iron alloy.
