Tungsten Carbide Extrusion-taps Introduction

Tungsten carbide extrusion-taps’ threaded portion has no cutting edge, relying on plastic deformation in the hole formed by extrusion screw.

Tungsten carbide extrusion-taps’ principle is the use of metal and plastic deformation processing thread of a new thread cutter, thread forming taps are no crumbs extrusion process, especially for the lower strength, good ductility of copper alloy and aluminum, can also be used for low carbon steel, stainless steel and low hardness, tapping the plastic material having a large, long life.

Tungsten carbide extrusion-taps’ threaded surface finish extruded, metal fiber thread is not broken, and the chilled layer formed on the surface layer can improve the strength and wear resistance of the thread. It solves the difficult problem of chip tapping fundamentally, because there was no debris, more conducive to the assembly of the tungsten carbide extrusion-taps’ thread. In electronics, plastics industry wide application.
