          • How high is the German forging technology? Steel is like pla

            Forging is one of the main processing methods to provide mechanical parts blank in machinery manufacturing industry. Forging can not only get the shape of the mechanical parts, but also improve the internal structure of the metal and improve the mechanical and physical properties of the metal. Chinas forging industry is developed on the basis of importing, digesting and absorbing foreign technology...

          • Difference between cold rolling and hot rolling

            cold rolling Cold: the recrystallization temperature of cold rolling is called the following general, hot rolled steel coil as raw material, after acid wash Descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the hard roll The strength and hardness of the rise and decline of toughness index, so stamping performance will deteriorate...

          • Selection of mould material

            The selection of mold material before we talk about the mold material, we must first understand some basic things of the injection mold. First, it is the classification of the mold. In general, the mold is divided into five stages according to the length of the service life. The first class is more than a million times, the two is 500 thousand ----100 million, the three is 300 thousand -----50 mill...
