Extrusion tap

Extrusion tap is a new type of machining internal thread with metal plastic deformation principleThread cutterThe internal thread extrusion, extrusion tap 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 service life.

Characteristic:
The thread surface of the thread extruded by the extruding tap is high, and the metal fiber of the thread is not brokenThe formation of a cold layer on the surface 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
