aluminum casting services

aluminum casting is used to produce zinc and aluminum parts, by injecting melting material – under high pressure – into reusable steel molds (also known as dies). They can be designed to produce very complicated parts with pin point accuracy. Our aluminum casting company manufactures parts with sharp definition, strong material integrity and smooth or textured surface finishes. Our company is a Tier 1 and Tier 2 supplier for the following industries:  Decoration industry, Furniture, Public facilities part, Electric accessory,pipe, electric field, etc.


Aluminum alloy Main material is ADC12, ADC10, A380, A360, A356/ alsi7mg, alsi12, alsi10mg, alsi9mg,etc.

For the surface treatment could be chrome, Sandblast, Electrophoresis, anodized, Polishing, Painting, Powder coating Polishing, Painting, Powder coating and so on.

Why aluminum Castings China?

Our full-service company specializes in manufacturing cast products made from aluminum and zinc alloy materials. Our knowledge, combined structured project management methods, supports customers from concept, through rapid prototyping, tooling and pre-production stages, as well as full-scale manufacturing.

Aluminum alloy die casting

Die-casting relies on pressure to hydraulically press aluminum or zinc into molds and equipment, and to shape the product at high temperatures, as shown in the following figure, but different parts still require special techniques and designs to complete the optimal mold structure and parts, to achieve the lowest cost and The best product, usually, die-casting parts will not be oxidized, other surface treatments can be based on parts requirements, such as spray painting is possible.

Aluminum alloy low pressure casting

Low-pressure casting, the biggest difference from die-casting is that its aluminum liquid is from bottom to top, like following shown, which is stabilized by a large and very stable pressure, and of course there is a very high temperature. Low-pressure casting can be used for relatively large parts, such as up to 1 meter and width of 300mm. There is also a very important point. Low-pressure casting can be used to make thicker products. Generally, 4mm wall thickness and thicker are no problem, once mold design is reasonable, and with rich experience, the product will not appear big sharkage.
