What is the features of die casting machine?
The main feature of die casting machine is that the molten metal fills the cavity under high pressure and high speed, and is formed and solidified under high pressure. The insufficiency of the die casting is: because the molten metal is in the process of filling the cavity under high pressure and high speed, it is inevitable The air in the cavity is wrapped inside the casting to form the subcutaneous pores, so the aluminum alloy die-casting parts are not suitable for heat treatment, and the zinc alloy die-casting parts are not suitable for surface spraying (but can be painted). Otherwise, the internal pores of the casting will expand upon heating as the above treatment heats, causing the casting to deform or bubble. In addition, the machining allowance of die-casting parts should also be smaller, generally about 0.5mm, which can reduce the weight of castings, reduce the amount of cutting processing to reduce the cost, and avoid the penetration of the dense layer on the surface, revealing the subcutaneous pores, resulting in The workpiece is scrapped.
