Precision casting processing industry in technology, quality and price are for southeast Asia and the Middle East and other countries, has been a lot of advantages, the outlook for exports is very good, its export casting products and also will become an important part of the casting export in our country.
Because our country precision casting production cost is much lower than abroad, now, with the gradually perfect and improve the quality of casting technology, not only can reduce the import of foundry, and is likely to expand export market, gradually to export more casting products abroad.
Precision casting during the process of production is mainly refers to obtain accurate size casting process, compared with the traditional sand mold casting, precision casting for more precise casting size, better surface finish, precision casting effectively includes the pressure casting, lost foam casting, investment casting, ceramic mold casting, metal mold casting, etc.
Precision casting in the market, also called lost wax casting, its products in the process of very sophisticated, complex, close to the final shape, can not machining or rarely used directly, so the investment casting is an advanced technology of formed near net shape.
The development of precision casting makes it not only possible to produce small castings, but also produce larger castings. The contour size of the largest investment casting is nearly 2m, while the minimum wall thickness is less than 2mm. At the same time, the mold casting is also more precise. Besides linear tolerance, the parts can also achieve higher geometric tolerances. The surface roughness of the investment casting is also smaller and smaller, which can reach ra0.4mm.http://www.pump-casting.com/
