Precision casting process and mechanical processing method

Precision casting process, although in recent years the accuracy of its products and complexity have increased, but the size precision and the surface quality is still less than the injection molding process; forging process is an important development, has been applied to the connecting rod mass production. But generally speaking, the life of the forging heat treatment cost and tooling is still a problem, pending further solve; the traditional machining method, recently by automation and enhance the processing capacity, have great progress in the effect and precision, but the basic procedure still do not take off a production step by step (lathe, planer, milling, grinding, drilling, polishing and so on) to complete the shape of the parts.

The machining precision of the machining method is much better than that of other processing methods, but because of the low rate of the effective use of the material and the shape of the limited in equipment and tool, some parts not a mechanical processing to complete and production efficiency lower. On the contrary, the MIM process can effectively make use of the material, and is not limited by the shape of the product, the shape of small, high difficulty of precision parts manufacturing, MIM process is the mechanical processing, the cost is low and the efficiency is high, with a strong competitive edge. MIM technology is not competition with traditional processing methods, but to make up for the shortcomings of traditional processing methods in the technical problems or can not be produced. MIM technology can be produced in the traditional processing methods in the field of parts to play its expertise.
