Today not only CNC aluminum milling in used in many industrial fields, but also with aluminum cast molds. The complex aluminum cast mold is a new technology to produce high quality aluminum molding with the core technology of electromagnetic pump low pressure casting technology, aluminum smelting and forming composite purification technology and manufacturing core. The electromagnetic pump low pressure casting metal melt transfer system has a stable flow, flow control is convenient, simple the process of melting alumina suction and easy to achieve the advantages of using the process of automation, which not only the casting quality of aluminum casting, [...]
