金属注射成形(MIM)：一种制造精密工程零件的竞争性工艺

Metal Injection Moulding(MIM):A Manufacturing Process for Precision Engineering Components

经过30多年发展,金属注射成形(MIM)已发展成一种生产小型、精密、复杂形状零件的具有竞争性的生产工艺。这类零件用常规金属工艺生产时,不但价格昂贵,而且材料利用率低与生产工艺复杂、费时。MIM工艺几乎可用包括金属、陶瓷、金属间化合物及复合材料在内的所有材料,生产大量与少量的小型复杂形状零件。现在。用MIM工艺生产的零件已在诸如汽车、化工、航空航天、事务机械、计算机硬件、生物-医疗器械及枪械等产业部门得到了广泛应用。

MM has over the past decades established itself as a competitive , manufacturing process for small precision components which would be costly to produce by alternative methods. It is capable of producing in both large and small volumes complex shapes from almost all type of materials inducing metals, ceramics, intermetallie compounds, and composites. Components made by MM technology are finding applications in industry sectors such as automotive, chemical, aerospace, business equiment, computer hardware, bio-medical and armaments.
