At present, the competition between
countries in the automotive industry is becoming increasingly fierce, the
prerequisite for winning in the fierce competition is the low cost technology
to produce high quality products, the automobile industry in the near net
forming processing production put forward higher requirements. The development
of metal powder injection molding (MIM) technology has greatly promoted the
development of automobile industry.
MIM combines the advantages of two kinds of
powder metallurgy and plastic injection molding technology, breaking the
traditional metal powder pressing molding process in product shape. MIM powder
metallurgy technology can be sintered to a dense, with good mechanical
properties and surface quality of mechanical parts. At the same time, the
plastic injection forming technology to large scale and high efficiency
production with many complexity characteristics of parts: such as a variety of
external grooving, external thread, the tapered outer surface, cross through
holes, blind holes, concave part and the pin key, strengthen rib plate, surface
knurling and so on, with to features of parts are unable to use conventional
powder metallurgy method, precision casting process of.
From the traditional powder metallurgy,
metal injection molding industry in full swing in recent years, the domestic
powder metallurgy industry seems to be growing. But horizontal comparison of
the manufacturing process industry, powder metallurgy, metal injection molding
in particular, the market is still just the tip of the iceberg. The number of
products and the value of enterprise production, not to mention the
"substantial".
