FIELD: extrusion and granulation of plastic materials. SUBSTANCE: hard alloy members are provided with reinforcing frames made from tool steel. Reinforcing frames are made fast to body. Wolfram-free hard alloy with nickel-and-chrome binder is used in the capacity of hard alloy. Each reenforcing frame has rib-like protrusions which faces are located on surface of spinneret. Working part of spinneret displays strength of tool steel and wear resistance of hard alloy antifriction materials. EFFECT: reduced usage of wolfram per unit of wear resistant surface of spinneret. 3 cl, 1 dwg
