Domestic metal injection molding industry product quantity and output value has a lot of room for improvement


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".
