Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity. The mould cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mould during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used. With a total of more than 100 machining equipment, such as CNC machinery, equipment specialized in polishing and grinding. The capability of manufacturing is up to diameters 600mm and length 10000mm. Meanwhile, a batch of advanced testing equipment, such as HRC tester, nitriding layer thickness tester, nitriding layer property tester, chrome gauge, which enable us testing microstructure, hardness, straightness, finish, thickness of nitriding layer and other tests. Chrome plated tie bar Material: 42CrMo, 40Cr, 1.7225, 1.7035, SCM440, SCr440, 4140, 5140 Available size: Diameter 50 - 600mm, length 1000 - 10000mm Chromium plating layer thickness: 0.02 - 0.08mm Surface hardness: above HRc55 ------------------------------------------ Ningbo Jinyi Precision Machinery Co., Ltd.
