Powder metallurgy products are used forming and sintering of metal
powder ( or mixture of metal powder and nonmetal powder ) is made of materials
and products technology. It is a branch of metallurgy and materials science .
Applications of powder metallurgy products is very wide , from general
machinery manufacturing to precision instruments ; from hardware tools to large
machinery; from electronics to the motor manufacturing industry ; from the
military industry to civilian industry ; from the general to sophisticated
high-tech technology , can see powder metallurgy figure
In corrosion resistance and high temperature performance, compared
with ordinary steel stainless steel can be thinner and more compact, so as to
achieve the purpose of weight reduction. Compared with castings and forgings
powder metallurgy, powder metallurgy auto parts lighter specific gravity (due
to pore more), plus its high precision, low cost reasons, it is used in the
auto parts more widely. Lightweight cast iron castings mainly in its gravity is
less than castings and forgings. In addition, the production process than cast
iron cast steel excellent abrasion resistance, cut resistance, thermal
resistance and vibration absorption, also superior to steel, cast iron instead
of steel, forgings trend in the car manufacturing increasingly large , instead
of ductile iron crankshaft forgings is the most successful example.
Auto parts supply work, the relationship between the production and
operation of enterprises huge supply shortage will affect production, excess
inventory, backlog of capital. For these situations, we focus on practical work
in the market mechanism, to explore a reasonable balance between supply and
demand of auto parts, suitable for the market economy and the establishment of
the characteristics of supply and demand mechanism itself, make a good supply
of auto parts production and management services for businesses. Possession of
the national economy can not be underestimated, the relevant departments should
closely cooperate fully imported cars function.
