Used Mim – Metal Injection Molding for sale (36,772)

Year of construction: 2024, condition: excellent (used), The ZLC series cold chamber die casting machines have been developed based on over 12 years of experience and are widely used for producing zinc or brass alloy components in sectors such as automotive, electrical engineering, electronics, toys, household appliances, and computers. These cold chamber die casting machines are equipped with high-quality imported hydraulic components, a robust machine frame, tie bars made from high-tensile alloy steel, and industry-specific control systems. Key advantages include advanced design, precision manufacturing, rapid response, easy operation, reliability, safety, and low energy consumption. The machine comprises a control system, hydraulic system, lubrication system, cooling system, clamping system, injection system, machine frame, safety door, and more. Its primary function is to extract a precise quantity of molten metal from a separate furnace, pour it into the injection sleeve, and, under high pressure, inject the completely molten alloy into a mold mounted on the platen. The die closes and the high pressure is maintained until the alloy fully solidifies inside the mold. Lhedpfsy A Hnyjx An Isi
