高压风缸是我公司主导产品之一,近年来生产量越来越大,但由于现行的缸套毛坯浇注工艺还是沿用几十年前的老工艺,致使缸套毛坯重量相对过大,铸件壁厚太厚,铸件废品率较高。为了彻底改变这一现状,我公司决定采用先进的砂套成形工艺取代老工艺,经试生产取得了成功。 1.传统的缸套毛坯浇注工艺情况 High-pressure cylinder is one of the leading products of our company. In recent years, the production volume is getting bigger and bigger. However, due to the existing cylinder blank casting technology or the old process which used decades ago, the cylinder blank weight is relatively large, Thick too thick, casting a higher rejection rate. In order to completely change the status quo, our company decided to use advanced sand forming process instead of the old process, the pilot production has been successful. 1 traditional cylinder blank casting process conditions
