Lost Foam Casting Technology

Qingdao Shengmei Machinery Co.,Ltd | Updated: Aug 24, 2018

The EPC process includes the design of gate and riser system, the control of pouring temperature, pouring operation and negative pressure. Casting system plays a very important role in EPC process, and is a key to the success of casting production. In the design of gating system, the particularity of this process should be considered. Because of the existence of mold clusters, the behavior of molten metal after pouring is very different from that of sand casting, so the design of gating system must be different from that of sand casting. In designing the sectional dimension of each part of the casting system, the resistance caused by the existence of the mold in liquid metal casting should be taken into account, and the minimum flow resistance area should be slightly larger than that in sand casting.
