现在已开始采用粉末冶金的喷射成型法制造中间凹的(under cut)和角凹的形状复杂的另件。微粒级的粉末金属首先要混以结合剂制备成基本料,再进行喷射成型。随后除去结合剂,便可进行烧结。此法是Parmatech Deuelopment Corp.发明的。采用此法喷射成型能制造壁厚为0.025
Powder injection metallization has now begun to make intricate undercuts and corner recesses of complex shapes. Particle-size powder metal mixed with the first binder to prepare the basic material, and then injection molding. Subsequently, the binder is removed and sintering can be carried out. This method was invented by Parmatech Deuelopment Corp. Using this method of injection molding can create a wall thickness of 0.025
