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.
