中文摘要:
      用金属注射成型方法研究三种热塑性蜡基粘接剂(高密度聚乙烯、高密度聚乙烯/聚丙烯、聚丙烯)对316L不锈钢尺寸稳定性及其机械性能的影响,对三种热塑性蜡基粘接剂溶剂脱脂过程进行了分析。实验结果表明用高密度聚乙烯/聚丙烯热塑性蜡基粘接剂得到的316L不锈钢注射成型件尺寸稳定性及机械性能较好,溶剂脱脂时间较短、效果较好,其长、宽、高三维尺寸稳定性比聚丙烯热塑性蜡基粘接剂得到的注射成型件分别高46 %,40 %,20 %,密度、硬度和拉伸强度分别为7.28 g/cm3、72.3 HRB和579MPa。

英文摘要:
      A thorough of thermoplastic polymer in the wax-based binder is essential for ensuring the dimensions and mechanical properties of 316L stainless steel metal injection molding parts. The effects of three thermoplastic polymers, High density polyethylene, High density polyethylene /Polypropylene and Polypropylene, on the dimensions and mechanical properties of 316L stainless steel metal injection molding parts have been compared in this paper. The tensile bar is tested to examine the dimensions and mechanical properties of sintered parts against different thermoplastic polymers in the binder. Among the three thermoplastic polymers in the binder considered herein, High density polyethylene /Polypropylene performs better than the others in solvent debinding stage and in terms of the metal injection molding compact quality. High density polyethylene /Polypropylene has significantly better length, width and thickness by up to 46%, 40%, 20%, respectively. The density, hardness and tensile strength of the sintered parts are 7.28 g/cm3, 72.3 HRB and 579MPa.
