Cast iron casting process of metal mold casting and die casting

The Cast iron casting process is a modern process for hollow casting molds made of metals (heat-resistant alloy steel, ductile iron, heat-resistant cast iron, etc.). The die casting of the cast iron casting process is the pressure casting of the metal mold on the die casting machine, and the die casting of the cast iron casting process is the most efficient casting process. So what are the metal mold casting and die casting of the cast iron casting process? Next, let us take a closer look.

Metal mold casting

The metal mold of the cast iron casting process can be gravity casting or pressure casting. The metal mold of the cast iron casting process can be reused. Every time you pour molten metal, you get a casting. The service life is very long and the production efficiency is high. Cast iron casting process Metal cast iron not only has good dimensional accuracy and smooth surface, but also has higher strength than sand cast iron, and it is not easy to be damaged when the same molten metal is poured. Therefore, in mass production of small and medium-sized non-ferrous metal castings, as long as the melting point of the cast iron material is not too high, metal casting is generally preferred. However, the metal mold casting of the cast iron casting process also has some disadvantages: because the processing cost of heat-resistant alloy steel and the cavity made on it is higher, the metal mold of the cast iron casting process is expensive, but the overall cost of the die casting mold is higher than that of that It's much cheaper. For small batch production, the cost of the mold allocated to each product is too high and generally not easy to accept. And because the metal mold of the cast iron casting process is limited by the size of the mold material and the capacity of the cavity processing equipment and the casting equipment, it is also helpless for particularly large iron casting. Therefore, the cast iron casting process is rarely used for the production of small batches and large parts. In addition, although the cast iron casting process uses heat-resistant alloy steel, the heat resistance of the metal mold of the cast iron casting process is still limited. Generally used for casting of aluminum alloy, zinc alloy, and magnesium alloy. It is rarely used in copper alloy casting. It is even less used for ferrous metal casting.

Die casting

The die casting machine of the cast iron casting process is divided into a hot chamber die casting machine and a cold chamber dies casting machine. The hot chamber dies casting machine has a high degree of automation, less material loss, and higher production efficiency than the cold chamber cast iron casting process to die casting machine. However, due to the heat resistance of mechanical parts, it can only be used in the production of cast iron with low melting point materials such as zinc alloys and magnesium alloys. Aluminum alloy dies castings, which are widely used today, can only be produced on cold chamber die casting machines due to their high melting point. The main feature of the cast iron casting process is that molten metal fills the cavity under high pressure and high speed, and is formed and solidified under high pressure. In addition, the machining allowance of cast iron casting process dies castings should also be smaller, generally about 0.5mm, which can reduce the weight of iron casting, reduce the amount of machining to reduce costs, and avoid osmotic iron casting. The dense layer on the surface. Expose the subcutaneous pores and cause the workpiece to be scrapped.
