Casting, sand casting, metal mold casting, etc., they are all we have to learn and understand the object, at the same time is also more widely used. So, they contains what specific content? We should learn and know what knowledge content? To solve these problems, the following is to explain in detail to carry out, so that everyone can be the aspects of learning, some knowledge of the growth in this respect, and be able to process.
Casting, it can be divided into gravity casting and pressure casting both, and the former may call it cast again. And the latter, it is cast by outside forces.
Sand mold casting, literally, as a way of foundry sand as the main material, usually by gravity casting this way. However, if you have any special requirements, also can use low pressure casting, centrifugal casting, etc. On the whole, the adaptability of sand mold casting is very broad,, simple parts, complex parts, such as size, can use sand mold casting, in addition, it also can be mass production. It is also flawed, however, is that each pouring time, only so the production efficiency is not high. The castings, dimensional accuracy is not high, and the surface is rough.
Metal mold casting, it is different with sand mold casting, because it is to use heat resistant alloy steel, and its casting mould can be used repeatedly without damage, thus can greatly improve the production efficiency. Also, for example, in the case of castings, the dimensional accuracy and surface roughness can also be greatly improved. So, in conditions allow, is generally preferred to choose metal mold casting. However, it's the only drawback is that the cost is not low.
