Metal Die Casting (Tiebars)

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.

We are specialized in manufacturing nitrided tie bars and traditional chrome plated tie bars injection molding machine and die-casting machine, together with matching guide rods, piston rods and other plastic machinery accessories.

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.
