Punch bar is based on high speed steel, powder high speed steel, tungsten steel and other molds suitable for processing with steel materials. Suitable for cold heading, cold extrusion, stamping, hydraulic, injection molding and other processing industries.

Punch is an important part of cold heading die, which can be divided into front punch and back punch according to its working position; it can also be divided into shaping punch, positioning punch, pilot punch, molding punch, stretch punch, slotted punch, punch, etc.; according to its shape, it can be divided into round punch, four corner punch, five corner punch, hexagonal punch and octagon punch There are many kinds of special-shaped punch, such as twelve angle punch, plum blossom punch, mother and child punch, star shaped punch.

HCVAC vacuum coating machine is applied to punching rod parts. No matter through higher productivity, more reliable production or higher efficiency, wear-resistant coating can save a lot of costs, and it has excellent wear resistance, greatly extending the tool life. High speed cutting and dry machining produce extremely high temperatures. Due to the excellent thermal stability, thermal hardness and oxidation resistance of the coating, the heat is dissipated through the chips without adversely affecting the cutting edge. Depending on the material to be processed and the processing steps involved, we provide the ideal coating for your application. Whether it's turning, milling, drilling, reaming, thread cutting or gear cutting - syn vacuum coating coating equipment can make your production faster, more efficient and more reliable.
