我厂液氧泵产品中使用的关键密封元件——凹迷宫片(见图1),原材料厚度仅为0.3毫米,H62-M,内外圆的尺寸精度要求都较高,原加工工艺烦杂,经济效益较差,因此我们设计了一套精密复合模以取代原有 The key sealing element used in our liquid oxygen pump products - concave maze (see Figure 1), the raw material thickness of only 0.3 mm, H62-M, both inside and outside the circular dimensional accuracy requirements are high, the original processing complex, economical Less effective, so we designed a sophisticated composite model to replace the original
