Extrusion tap is the use of metal plastic deformation principle and internal thread processing of a new type of thread cutting tools, thread extrusion extrusion Taps is a chipless machining process, 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, long life. With the extrusion tap extrusion thread surface finish, metal fiber thread is not broken, and form a layer of hardened layer 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.
