EPC EPC flask is the production of key equipment, the EPC process plays a very important part. The device is used in large, medium and small castings, multi-model combinations, sand box specifications, improve casting yield and reduce the manufacturing cost of casting. Depending on the application complexity into simple sand box and sand boxes. Box with steel plate, channel, stainless steel mesh, seamless steel tubes and other combinations irons shaped appearance and durable. Complex flask into hoppers and side discharge, generally within five surface pumping and pumping and other solid six-sided type, can reach the most reasonable course when negative pressure inside the vacuum casting in sand, the cast of Full cast me good shape, there is no defect, sand box sales, convenient unloading sand. For some simple shape, uniformity, pouring negative field of less demanding castings, Anqiu sand box, you can use a simple sand box, usually dumping type, divided into three pumping, pumping four, five surface pumping substandard solid type. flask shall be welded firmly to ensure a sand box does not crack under load. Before using the earlier recommendations with simple support continual bridge construction, steel production using sand box, as a temporary seat use, high strength, good stability, sand box factory, easy removal, easy to operate, to ensure construction safety, meet by force requirements. Also sand box can also be used in Prestressed construction put sheets and cast bracket demolition. Sand box sales, Dragon Industrial (certified), sand box provided by the Shandong Anqiu Julong Industrial Development Limited. Shandong dragon Development Co., Ltd.
