Resin Sand Casting

Die casting is the pressure of metal molds on a die casting machine and is the most productive casting process. Die-casting machines are divided into two categories: hot-chamber die-casting machines and cold-chamber die-casting machines. The hot chamber die casting machine has a high degree of automation, less material loss, and higher production efficiency than the cold chamber die casting machine. The aluminum alloy die castings that are widely used today can only be produced on cold chamber die casting machines due to their high melting point. The main feature of die casting is that the molten metal fills the cavity under high pressure and high speed, and is formed and solidified under high pressure. The air in the cavity is wrapped inside the casting to form subcutaneous pores, so aluminum alloy die castings should not be heat treated, and zinc alloy die castings should not be sprayed on the surface (but can be painted). Otherwise, the internal pores of the casting will expand due to thermal expansion and cause the casting to deform or bubble when the above-mentioned treatment is performed. In addition, the mechanical cutting allowance of die castings should also be smaller, generally around 0.5mm, which can not only reduce the weight of castings, reduce the amount of cutting to reduce costs, but also avoid penetrating the surface dense layer and exposing subcutaneous pores, causing The workpiece is scrapped.
