The wire drawing process of wire drawing film is a common processing process of metal products. In metal pressure machining. Under the action of external force, the metal is forced through the die, the metal cross-sectional area is compressed, and the required cross-sectional area shape and size are obtained. The technical processing method is called metal wire drawing process.
Wire drawing process is to implement further texture processing on the finished metal surface, which can not only change the shortcomings of the original mechanical grain or surface, well cover the mechanical grain and mold closing defects in production, but also make regular and relatively uniform new veins, so as to achieve an appearance decoration effect like silk satin. It is mainly used for stainless steel, aluminum, copper Iron and other metal products.
