摘　　要：以17-4PH不锈钢粉末为原料,采用PW+PE+SA作为粘结剂,分析了粉末注射成形所用喂料的制备工艺。得出了喂料搅拌时间、石蜡所占比例对喂料质量的影响。结果表明:采用PW(62%)+PE(33.1%)+SA(4.9%)作为粘结剂,混料时间在50min时能够保证喂料的良好特性。Using 17-4Ph stainless steel powder as raw material, adopting PW＋PE＋SA as binder, the preparation technology of feedstock used in powder injection molding was analyzed. The effects of mixing time of feedstock and PW ratio on the quality of feedstock were obtained. The result shows that adopting PW（62%）＋PE（33.1%）＋SA（4.9%） as binder, the good characteristics of feedstock can be ensured by mixing time for 50 min.
