Remington武器公司最近发展一种新型注射成型材料“注射合金”。该材料由超细金属颗粒与一种塑性成形剂结合,采用热塑模压设备注射成形。金属颗粒球径小于10μm,成形剂改善材料的流动性使模腔装填处于最佳。成形剂在出模溶解或在加热中消除,材料在高温下烧结。超细金属颗粒加快扩散速 Remington Arms Company recently developed a new injection molding material “injection alloy.” The material consists of ultrafine metal particles combined with a plastic forming agent, using thermoplastic molding equipment injection molding. The metal particles have a diameter of less than 10 μm and the forming agent improves the fluidity of the material so that the cavity filling is optimized. The forming agent is dissolved in the mold or eliminated in the heating, and the material is sintered at a high temperature. Ultra-fine metal particles to speed up the diffusion rate
