You need to tell me to let my work suit your! www.jscmetal.com hot forging a high strength, light weight, in terms of reliability than the casting material. Therefore, it is widely used as a reinforcing member in aircraft, ships, vehicles, machinery, electronic instruments. Especially in the aviation industry, requiring high reliability use of forged part. Sand casting is a kind of sand as the main form of material, production mold of the traditional casting process. Sand generally use gravity casting, may also have low pressure casting, centrifugal casting process when there are special requirements. Sand casting wide adaptability, small pieces, large, simple parts, complex parts, a single, large quantities can be used. Sand casting molds, before Wood Productions, known as wood mold. Wood mold disadvantage is easily deformed, easy to damage; in addition to single-piece production of sand casting, you can use a high dimensional accuracy and a long life aluminum mold or resin mold. Although the price has increased, but still cast metal type than the much cheaper molds used in the production of small batches and large, the price advantage is particularly prominent. In addition, sand refractoriness higher than the metal type, and thus a higher melting point materials such as copper alloys and ferrous metals, also adopt this technology. However, sand casting, there are some shortcomings: Because each sandy mold casting only once, after obtaining the casting mold that is damaged, it must re-shape, so the lower sand casting production efficiency; and because the whole nature of soft sand The porous, so the lower sand casting casting dimensional accuracy, surface too rough. Metal casting is heat-resistant alloy steel casting mold hollow mold modern technology. Mold can use gravity casting, pressure die casting can also be used. Metal type casting mold can be used repeatedly, each time pouring molten metal casting to get a life long, high production efficiency. Metal mold casting is not only good dimensional accuracy, surface finish, and in the same pouring molten metal case, which cast a higher strength than sand, but not easily damaged. Therefore, in the mass production of non-ferrous metals, when casting small, as long as the melting point of the casting material is not too high, are generally preferred metal casting. However, metal casting, there are some shortcomings: Because heat-resistant alloy and processing on it to make a hollow cavity are relatively expensive, the metal type of mold is not cheap, but overall and die casting tooling costs are cheaper compared to more. For small batch production, the share of each product on the tooling costs significantly too high, generally difficult to accept. And because the metal type mold mold material size and equipment, limiting the ability of cavity machining casting equipment by, so particularly large cast also appears powerless. Thus in the production of small batches and large, rarely used metal casting. In addition, although the use of a metal mold heat-resistant alloy, but the heat capacity is still limited, generally used for aluminum, zinc alloy, magnesium alloy casting, has been rarely used in the copper alloy casting, and for the ferrous metal casting even less.
