高压造型就是在高压制成的砂型中得到铸件的铸造方法,是一种新的工艺,在苏联、捷克、美国等国已成功地应于生产,所得铸件的表面光洁度不低于▽▽_4可达▽▽▽_7,精确度也很高,可以代替壳型铸件,壳型铸造在我国自从1956年研究应用以来,由于必须应用目前缺少的,价格昂贵的粘结剂—树脂而难于大量推广,许多工厂因树脂供应问题成本问题而停 High-pressure molding is the casting method of casting obtained in the high-pressure sand mold. It is a new process that has been successfully applied in the countries of the Soviet Union, the Czech Republic and the United States. The surface finish of the resulting castings is not less than ▽ ▽ _4 Up to ▽ ▽ ▽ _7, the accuracy is very high, you can replace the shell castings, shell casting in our country since 1956 research and application, due to the current lack of application of the expensive binder - resin and difficult to promote a large number, Many factories stop because of the cost of resin supply
