黄铜外壳(图1)是仪器仪表接插件安装连接用的一个主要零件。原来采用由棒料切削加工的方法制造,加工难度高、合格率低,材料利用率仅12％。现改用温热挤压工艺一次成形,经过多次试验,已由研制阶段进入正常生产,收到了明显的经济效益(图2,表1)。 The brass housing (Figure 1) is a major part of the instrumentation connector installation and connection. Originally used by the bar cutting method of manufacturing, processing high difficulty, low pass rate, material utilization rate of only 12%. Now use the warm extrusion process once formed, after many tests, has entered the normal production stage, has received significant economic benefits (Figure 2, Table 1).
