一、酯硬砂铸造生产线类型 铸造生产线内容包括造型(制芯)生产线、砂处理线及落砂清理线。酯硬砂生产线与树脂自硬砂生产线相似,较粘土砂简单、易实现。造型(制芯)生产线的类型大致有四种形式。 (1)采用间歇式混砂机的中小型(芯)生产线这种形式是开始使用有机酯水玻璃自硬砂的厂常常采 First, the type of ester hard sand casting line Casting production line includes modeling (core) production line, sand processing line and off the sand cleaning line. Ester hard sand production line with the resin from the hard sand production line similar to clay sand simple and easy to implement. Molding (core) The type of production line roughly four forms. (1) Small and medium sized (core) production line with batch mixer This type of plant is often used to start using organic ester water glass self-hardening sand
