一、前言 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,其基本工艺过程为:首先是选择符合MIM要求的金属粉末和粘结剂,然后在一定温度下采用适当的方法将粉末和粘结剂混合成均匀的注射成形喂料,经制粒后在注射成形机上注射成形,获得的成形坯经过脱脂处理后烧结致密化成为最终成品。 金属注射成形技术在制备具有复杂几何形
I. Introduction Metal Injection Molding (MIM) is a new near-net-shape powder metallurgy technology derived from the plastic injection molding industry. The basic process is as follows: Firstly, select the metal powder that meets the MIM requirements and Binder, and then at a certain temperature using a suitable method of mixing the powder and binder into a uniform injection molding feed, after injection granulation on the injection molding machine, the resulting blank after degreasing sintering densification Become the final product. Metal injection molding technology in the preparation of complex geometry
