摘要
金属粉末注射成形技术是现代塑料注射成形技术与粉末冶金技术相结合形成的一门新型粉末冶金近净成形技术。该方法工艺过程与塑料注射成型工艺过程在原理上是一致的,其设备条件也基本相同,只是M IM注射成型的零件还需要后续脱脂,烧结等形成成品零件。其工艺特点决定其特别适宜生产小形体,复杂形状,大批量的零件。通过研究大批量生产微小齿轮的工艺过程,得到较为合理的工艺参数和生产出合格的制件。
Metal powder injection molding is a new net-shape forming technology,which is the result of plastic injection technology combined with powder metallurgy technology. This technology has the same principle with plastic injection technology, the equipments are also similar with the plastic injection method, the difference is that the part which produced by MIM need remove resin and sinter to get the finished part. The feature of this technology make it suit to produce small complex shape and quantity products. This paper det discussed the process of producing a certain microminiature gear using MIM technology and got reasonable parameters of the process and also the qualified product.
