Extrusion tap is the use of metal plastic deformation principle of a thread cutter and internal thread processing, extrusion extrusion tap internal threads are non chip processing technology, especially suitable for low strength, good plasticity and copper alloy Aluminum Alloy, can also be used for stainless steel and low carbon steel, low hardness, large plastic materials tapping life is long. The thread surface of the thread extruded by extruding tap is high, the metal fiber of the thread is not broken, and a cold layer is formed on the surface, which can improve the strength and wear resistance of the thread. It fundamentally solves the problem of chip removal in tapping, because of no chips, more conducive to the assembly of threads. It is widely used in electronics and plastics industry.
