        金属注射成形(Metal Injection Molding,简称MIM)是一种从塑料注射成形行业中引伸出来的新型粉末冶金近净成形技术,众所周知,塑料注射成形技术低廉的价格生产各种复杂形状的制品,但塑料制品强度不高,为了改善其性能,可以在塑料中添加金属或陶瓷粉末以得到强度较高、耐磨性好的制品。近年来,这一想法已发展演变为最大限度地提高固体粒子的含量并且在随后的烧结过程中完全除去粘结剂并使成形坯致密化。这种新的粉末冶金成形方法称为金属注射成形。

        Metal injection molding(MIM) is a new kind of powder metallurgy near-net forming technology which is introduced from the plastic injection molding industry. It is well know that plastic injection molding technology produces various complicated shapes products at a low price. But the strength of these plastic products is not high. In order to improve its performance, the metal or ceramic powder could be added to the plastic to obtain the products with high strength and good wear resistance. In recent years, this idea has evolved to maximize the content of solid particles and completely remove the binder and densify the preform during subsequent sintering. This new powder forming process is called metal injection molding.
