Different Size Cemented Carbide Moulds Cold Heading Dies for Cold Pressing Screw

Detailed Description:

Cold heading involves forming a piece of metal by applying pressure beyond its elastic limit. It is most commonly used on steel and stainless steel, which are popular for their strength and corrosion resistance. This process results in a dense product with an excellent surface finish. Some advantages of cold heading include a more uniform surface finish and fewer metal inclusions. While this process involves a higher level of detail than hot heading, there is minimal waste. Therefore, it is often the first choice of many companies and manufacturers
