Cold Header uses high speed automated "cold-headers” or "part formers” to transform a wire into an intricately shaped part with tight and repetitive tolerances. The process is volume specific and uses dies and punches to convert a specific "slug” or blank of a given volume into a finished intricately shaped part of the exact same volume. Cold Header is specially designed for the mass production of the fasteners, especially screws and bolts.
Based on the thread length, diameter and forging force, our Cold Header can be further classified into Z25 Series, Z12 Series, Z18 Series, Z41 Series and Z47\Z46 Series.
YSD, as famous Cold Header Supplier, has been listed on the Shenzhen Stock Exchange since 1998. We have established 30-year cooperation with Belgium LVD Company and started to introduce its machine tool technology in 1981. YSD occupies more than 80% market shares in the field of Cold Header processing in China.
