Powder metallurgy is the preparation of
metal powder or with a mixture of metal powder or metal powder and metal
powder) as raw material, through forming and sintering, preparation of metal
materials, composite materials and products of various types of industrial
technology. With the popularity of powder metallurgy products in the market,
the principle for the majority of users are more concerned about the technology
of powder metallurgy. So ZCMIM today to explain: the principle of powder
metallurgy, up to understand it:
1, the production of raw materials, we will
according to the specific use of the product to determine the powder metallurgy
processing of raw materials, there are many different types of metal powder and
a variety of metal powder has different performance, processed products also
has different performance, only to choose a good production of raw materials,
to produce the most suitable products.
2, press forming and by selecting the raw
materials to produce we can carry on production and processing, will be selected
out of the metal powder by a professional mold for molding and forming method
of the general with compression molding and compression molding.
3, after forming the needs of products
after sintering process can make produced have better mechanical properties,
more in line with the needs of the user. In general, we can use two methods of
unit system sintering and multiple sintering to carry out the sintering process
of powder metallurgy products.
4, sintering after treatment, due to
various kinds of powder metallurgy products, so some need to carry out some of
the sintering process, in order to meet the needs of users.
