Squeezing wire tapping is the application of plastic forming method, which uses pressure grinding in the lower hole to make the workpiece bulge and form threads. Because it does not produce chips and there is no chip groove, it is also called a non groove (chip) wire attack. This thread or thread will not be damaged due to chip blockage or other issues. Squeezing wire tapping is most suitable for materials with plasticity such as aluminum, red copper, zinc, brass, and low carbon steel. Our company has two types of extrusion wire taps, N-RS/N+RS (gray white) and N-RZ/N+RZ (black). There are two types of cutting parts for extrusion wire tapping: four tooth and two tooth. When using extrusion thread tapping, the size of the lower hole needs to be selected according to its accuracy requirements in order to produce high-precision and high-quality threads. Our company has a variety of extrusion wire taps with different precision levels for customers to use. There are two types of extrusion wire tapping: oil groove and no oil groove. Oil free groove marked as "L-shaped"
