本文评述巴台尔哥伦布实验室研究射压造型法生产粉末的计划。近几年来,人们日益广泛地用射压造型法制造形状复杂的铁、镍、铌、钼和其它易还原、易烧结的的中小型粉末冶金部件。虽然从生产的角度来看,这种方法的,可行性已完全肯定了,但是配制粉末含量极高、粘结剂比例很低的型砂技术尚未研究出来。研究射压造型工艺和粉末/粘结剂的配比一直是采用 This article reviews Columbus Columbus Laboratory’s plan to study powder production by the pressure molding process. In recent years, the shape and complexity of iron, nickel, niobium, molybdenum and other easily-reducible and easily sintered small and medium-sized powder metallurgy parts have been increasingly and widely used in injection molding. Although the feasibility of this method has been completely confirmed from a production point of view, no sand technology has been developed to formulate very high powder content and low binders. Research injection molding process and powder / binder ratio has been used
