Comparison between MIM technology and precision manufacturing and traditional machining

MIM process and the traditional powder metallurgy method is used in the die casting process of aluminum and zinc alloys, such as low melting point, liquid flow of good material. The product of this process is limited by material, its strength, wear resistance and corrosion resistance are all limited. MIM process can be processed raw materials more.

Precision casting process, although in in recent years the product precision and complexity are improved, but still less than dewaxing process and MIM process, powder forging is an important development, has been applied to the connecting rod mass production. But in general, the forging heat treatment in engineering cost and die life is still a problem, yet to be further solved.

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.

Machining method is much better than other processing methods, but because of the low efficiency of the material, and its shape is limited by equipment and tools, some parts can not be completed with mechanical processing. On the contrary, MIM can effectively make use of the material, without restriction, for 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.

Application of cemented carbide tools

Hard alloys can be used in the chemical vapor deposition method has been coated with titanium carbide, titanium nitride, aluminum oxide hard or composite layer. Is the development of physical vapor deposition method can be not only used for hard alloy tool, can also be for high-speed steel cutting tools, such as drill hob, taps and milling. Hard coating as hinder chemical diffusion and heat conduction of the barrier, the cutting tool in the cutting wear slower. The life of blade coating and coating compared to increase about 1 ~ 3 times

Because in high temperature, high pressure, high speed, and in corrosion of fluid medium, the parts, the application of difficult to machining materials more and more, the level of automation of machining and on machining accuracy requirements become more higher.

In order to adapt to the situation and direction of development of the tool will be the development and application of new cutting tool materials; further development tool of gas phase deposition coating technology, with high strength and high toughness matrix deposition higher hardness of the coating, the better to solve tool material hardness and strength of the spear shield; in the further development of the structure of indexable tool; improve the manufacturing precision of the cutting tool, reduce the difference between the quality of the products and make the tool used to achieve optimization.

Comparison between MIM technology and precision manufacturing and traditional machining

MIM process and the traditional powder metallurgy method is used in the die casting process of aluminum and zinc alloys, such as low melting point, liquid flow of good material. The product of this process is limited by material, its strength, wear resistance and corrosion resistance are all limited. MIM process can be processed raw materials more.
