METHOD FOR PRODUCING CEMENTED CARBIDE PRODUCTS

摘要

A method for injection molding or extrusion of cemented carbide or cermet parts uses a binder system, including 20-70 wt-% olefinic polymer, 30-80 wt-% wax. The olefinic polymer is a co-polymer of polyethylene and poly(alpha-olefin). By using such a binder system, a tougher material behavior of the green body and a lower temperature during the injection molding or extrusion is achieved.
