1.PIM Technical Concept and Technical Characteristics
Powder Injection Molding Technology combines the advantage of both powder metallurgy and plastic injection technology. It breaks the shape limit of conventional PM compression molding, while absorbs the capability of forming complex shape and realizing mass production with high efficiency of plastic injection technology. As a near net shape technology for high-quality precision components,Metal Powder Injection Molding (MIM/PIM) in china has the advantages which conventional powder metallurgy, precision machining and casting methods would not have. Here shows these advantages as following:
â—‡Capable of production complex shape small metal parts as plastic injection process. Powder injection molding parts typical weigh is 0.1-200g;
â—‡Capable of forming kinds of complex shapes, such as external cuts, threads, tapered external surface, cross holes & blind holes, slots, ribs&webs, knurling, and so on.
â—‡Good surface finishes and high precision dimensions(typical in±0.3%~0.5%)
◇Wide range of material optional for MIM process. Parts with high density (typical 95%~99% relative density) and homogeneous structure and excellent performance easy to acquire;
â—‡ Able to realize high-volume production with stable quality and high efficiency.
Table 1 and 2 show the comparison between MIM and other processes.
