The casting manufacturer was established in 1995. We are a fully integrated manufacturer of aluminum die casting, squeeze casting, CNC machining, and in-house tooling services.
We have applied for an invention patent for our newly developed aluminum squeeze casting process. Unlike conventional die castings, squeeze castings come with zero internal porosity, higher density, and similar mechanical properties to aluminum forgings, making them suitable for industries requiring lightweight and high-strength features, especially in the automotive industry.
We manufacture high-quality and precise aluminum casting blanks that comply with specific requirements. We also offer surface finish and CNC machining services to ensure that the casting blanks are prepared and finished to the customer's expectations.
Our products are mainly exported to North American and European markets. We have rich experience cooperating with foreign customers and in-depth knowledge of their requirements.
There are many different surface treatment technologies for aluminum casting parts. We can provide most of them according to customer requirements, such as sandblasting, shot blasting, spraying, anodizing, electrophoresis, and other surface treatments.
We are committed to providing products with high-quality finishes to meet a wide range of needs, from improving corrosion resistance and adding decorative features to improving performance.
Shown here are some of our surface-treated aluminum casting products.

We have found a solution to effectively solve the problem of porosity defects in traditional aluminum castings--our patented squeeze casting process.
We started to research and develop the squeeze casting process in 2015. As a China professional squeeze casting manufacturer, we own one squeeze casting manufacturing base with the patented squeeze casting process and equipment.
Our aluminum squeeze casting parts can eliminate defects such as internal porosity and shrinkage and have a dense internal organization.
Squeeze casting is a more advanced process than conventional aluminum casting methods. It can eliminate defects that exist in the traditional casting processes such as porosity and shrinkage, and the internal structure of the casting is more dense. Heat treatment and welding are acceptable.
