In the process of making aluminium castings, pure aluminium or aluminium alloy equipment and devices are mainly produced by casting. Generally, sand or metal molds are used to heat liquid aluminium or aluminium alloy into the die cavity. Aluminum parts or aluminium alloy parts of various shapes and sizes are usually called aluminium pressing. Castings.
Aluminum casting is a new technology which takes electromagnetic pump low pressure casting technology as the core, aluminum smelting and molding compound purification technology and manufacturing core, and produces high quality aluminum casting. The advantages of electromagnetic pump low-pressure casting metal melt transmission system are stable flow, convenient flow control, alleviating the inverted suction of molten alumina in the process and easy realization. It can not only improve the casting quality of aluminium castings, but also improve the working environment. Reduce labor intensity and realize automatic and modern casting production.
To a certain extent, aluminum castings are an important part of the purified fused enamel alloy castings. When used, they are 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 has an independent thermal insulation/heating system that can be used for mass continuous production as well as intermittent production. This technology has the advantages of high purification efficiency, long service life, low cost, effective, easy installation, use and flexibility.
The quality of aluminium castings to solve complex problems has three main aspects:
(1) Melting and melting of molten aluminium.
(2) Smooth transition aluminium metal halide lamp
(3) Size and stable die and core process.
Core manufacturing process modeling can see that casting quality and production have a direct impact. Casting porosity, viscous sand, scar, pyrolysis, surface quality and dimensional accuracy have a very good relationship with the properties of sand. The new technology of modeling and manufacturing is that PEPSET core resin binder is used for resins of original zirconia sand from hard sand. The difficult self-hardening sand mechanism is an independent, non-hardening chemical reaction. It is time to start hardening. Once the hardening reaction starts quickly. So the coach bag, because in a hard, high strength, small fat gas collapse, has good performance is the complexity of the casting surface, to ensure the quality and stability of dimensional accuracy.
