自硬树脂砂在铸造上的应用日益广泛,尤其在解决一般铸造技术上难以达到要求的高质量铸件上,能起到独特的效果。而石墨树脂砂则是树脂砂的特殊应用,它解决了铸件的特殊技术要求。本公司生产的燃气摩托压缩机产品,其中铝合金叶片形状精度,几何尺寸精度以及以表面光洁度都要求很高。除与机体连接的把柄外,均不机加工。要求 The application of self-hardening resin sand in castings is more and more widely used, especially for the high-quality castings that are difficult to meet the requirements of general foundry technology. The graphite resin sand resin sand is a special application, it solves the casting of the special technical requirements. The company produces gas motorcycle compressor products, of which aluminum alloy blade shape accuracy, dimensional accuracy and surface finish are demanding. In addition to the handle connected to the body, are not machined. Claim
