3, strengthen the strength of the attack tooth: extrusion wire tapping will not break the processing material tissue fiber, so the extrusion thread strength is higher than the tapping thread strength.

TaiwanGULINGExtrusion wire tapping adopts imported high speed steel containing cobalt as raw material, and has the following advantages:

1, no chip processing: because the extrusion wire tapping is through cold extrusion, workpiece plastic deformation to complete, especially in the blind hole processing, there is no chip removal problem, there will be no chip extrusion, wire tapping is not easy to break.
2, no transition tooth thread: extrusion wire tapping can be guided by its own processing, more suitable for CNC processing, but also make the transition teeth processing possible.
3, strengthen the strength of the attack tooth: extrusion wire tapping will not break the processing material tissue fiber, so the extrusion thread strength is higher than the tapping thread strength.
4, higher production efficiency: it is because of a longer service life, faster processing speed, the use of extrusion silk function to reduce the time to replace wire tapping and standby, so as to improve production efficiency.
5, tap own strength is good: because the squeeze wire tapping without chip removal groove, its own strength than cutting wire tapping will be much better.
6, longer service life: due to the extrusion wire tapping will not occur cutting edge passivation, chipping and other issues, under normal circumstances, its service life is 3-20 times the cutting wire tapping.
7, higher product qualification rate: due to extrusion wire tapping is no chip processing, the processing of thread precision and wire tapping consistency is better than cutting tap. The cutting taps are finished by cutting. In the process of cutting iron scraps, the scrap margin of the iron filings is less, which makes the qualified rate lower.
Extrusion wire tapping

Extrusion tap: a new thread cutting tool, which uses metal plastic deformation principle to process internal thread, which is used to press the cutting material to form thread in the lower hole. Because there is no chip, there is no chip removal groove, so also known as no groove (chip) wire attack. This thread will not damage threads or wires because of chip clogging and other problems. When the extrusion wire is used, the size of the lower hole must be chosen to meet the requirement of accuracy, so as to extrude the high precision and high quality thread.

The following is the bottom sheet extrusion screw tap:
