Aluminum castings refer to equipment and devices made of pure aluminum or aluminum alloys by casting. Generally, aluminum or aluminum alloys heated to liquid form are poured into the mold cavity using a sand mold or a metal mold, and the aluminum parts or aluminum alloy parts of various shapes and sizes are usually called aluminum die castings.
Modern molding technology for aluminum casting
Complex aluminum casting casting is a new technology with electromagnetic pump low-pressure casting technology as the core, aluminum smelting and molding composite purification technology and manufacturing industry as the core, and the production of high-quality aluminum castings is a modern technology. The electromagnetic pump low-pressure casting metal molten liquid transmission system has a stable flow, convenient flow control, and eases the back suction of molten alumina in the process. The advantages of easy implementation are the automation of the use process, which not only improves the casting quality of aluminum castings, but also improves the working environment. Reduce labor intensity and realize automation and modernization of casting production.
Purification of molten enamel alloy castings is an important part of aluminum smelting and composite purification facilities in addition to gas injection and spin foam ceramic filters with high degassing performance, unless there are metal inclusions. In addition, it uses a new long-life lining material, with an independent insulation/heating system that can be used for large-scale continuous production, as well as intermittent production. This technology has high molten aluminum purification efficiency, long life, low cost, effective, easy to install, use and flexible. Casting experience tells us that to solve the complex problems of quality aluminum castings in three main aspects:
(1) molten aluminum smelting and melting;
(2) smooth transition of molten aluminum to metal halide lamps;
(3) size and stability of mold and sand core process.
Core manufacturing process modeling can see the direct impact on casting quality and output. Casting porosity, sand sticking, scar, thermal cracking and surface quality, dimensional accuracy, the relationship between the sand performance is very good. The new technology for modeling and manufacturing is PEPSET core resin binder used for the original zircon sand resin from hard sand, the kind of difficult self-hardening sand mechanism an independent, non-hardening chemical reaction initially, when it starts to harden, the curing reaction once started fast. So the coach bag, because in a hard, high-strength, fat gas collapse small, has good performance is the complexity of the casting surface, ensuring the quality and stability of dimensional accuracy.
