冷凝树脂砂铸造工艺是用树脂作为粘结剂,用酸作固化剂,在室温下硬化成型的新型铸造方法.其尺寸精度和表面光洁度比目前生产中使用的粘土砂铸造生产的铸件有明显提高.六二一所研制的冷凝树脂砂铸造工艺方法与国际水平相当。本成果经过鉴定,并获得航空部三等成果奖.
Condensation resin sand casting process is a new type of casting method using resin as a binder and acid as a curing agent and curing at room temperature, and the dimensional accuracy and surface finish are significantly improved compared with the castings produced by clay sand currently used in production June 21 developed a condensed resin sand casting process with international standards. The results have been identified and won the third prize of the Ministry of Aviation Award.
