The complex aluminum casting is a new technology based on the electromagnetic pump low pressure casting technology, the core technology of aluminum smelting and shaping and composite manufacturing, and the core of manufacturing industry, so as to produce modern technology of high quality aluminum castings. Electromagnetic pump in low pressure casting molten metal transfer system has a stable flow, flow control, convenience, ease the process of fused alumina inverted suction and easy implementation of the automation is the use of the process, improve the quality of casting aluminum castings not only casting, but also can improve the working environment. Reduce labor intensity and realize automatic and modern foundry production.

An important part of the purified fused enamel alloy castings is aluminum smelting and composite purification facilities, except for gas injection and spin foam ceramic filters with high degassing performance unless metallic inclusions. In addition, it uses a new long life lining material, and an independent thermal insulation / heating system can be used for a large number of continuous production and also for intermittent production. The technology has high purification efficiency, long life, low cost, easy installation, use and flexibility. The quality of aluminum castings to solve complex problems should be taken into consideration in three main aspects:

(1) melting and melting of aluminum liquid,

(2) smooth transition molten aluminum halide lamp,

(3) the size and stability of the mold and the sand core process.
