Precision casting
Sep 13, 2017

In terms of technology, quality and price, China Precision casting processing industry have great advantages comparing to Southeast Asia, Middle East and other countries. Export prospect of the entire product is very gratifying, and its casting of the resale and export will also be important for China's exports component.

As China's precision casting production costs much lower than abroad, and now with its casting technology quality gradually improved, now we can not only reduce the imports of casting, but it is possible to gradually open up the export market, and export to abroad more casting products.

The main manufacturing process of precision casting is to obtain precision casting process in general, compared to the traditional sand casting process, precision casting castings have more accurate size, better surface finish, precision casting, including the pressure casting, Mold casting, investment casting, ceramic casting, metal casting and so on.

Precision casting in the market is also known as lost wax casting, and the product in the process is very sophisticated, complex, close to the final shape of the parts, can be directly used with machining or  rarely machined. So the investment casting is a near-net shape of the advanced technology.

The development of precision casting makes the investment casting not only can produce small castings, but also can produce larger castings. The largest size of castings is nearly 2m, while the minimum wall thickness is less than 2mm. At the same time the investment casting is also more sophisticated, in addition to linear tolerances, the parts can achieve high geometric tolerances. The surface roughness of the investment casting is also getting smaller and smaller, reaching Ra0.4μm.
