Custom Die Casting Parts Service

Pressure die casting is an ideal method for making large quantities of metal parts with excellent surface finish and dimensional stability.We provide cast parts in aluminum, zinc and magnesium.

Why Choose Die Casting Parts Machining?

When it comes to manufacturing high-quality metal parts, die casting is one of the most popular and efficient methods. This process involves injecting molten metal into a mold at very high pressures, which allows for the creation of complex and precise parts with a smooth surface finish. die casting parts machining is an efficient, durable, versatile, and cost-effective manufacturing method that is ideal for producing high-quality metal parts. 

If you are in need of metal parts for your business or project, die casting is definitely worth considering. Longsheng adopts the latest die-casting technology to provide high quality on-demand components. For aluminum and zinc materials, typical tolerances are usually in the ±0.05 mm to ±0.1 mm range, depending on the customer’s specifications.

Die Casting Parts Machining Surface Treatment Option

Surface treatment is the last step of precision die casting parts processing. It can be used to remove surface defects of castings, enhance mechanical or chemical properties, and improve the appearance of products. Users can choose different surface treatment processes according to different needs

Components made of zinc and zinc-aluminum alloy are very resistant to corrosion and can be retained in this state while remaining as is after die casting. But magnesium and aluminum require coating to resist corrosion.

Aluminum components are usually anodized. Type II (sulfuric acid) anodizing results in a corrosion-resistant oxidized surface on the component surface. Different colors can be used to anodize parts, including black, gold, clear, and red.

Type III (hard) anodizing can form a thicker surface layer and produce a waterproof layer, and has the corrosion resistance of Type II anodizing. Anodized parts do not conduct electricity.

All parts produced by die casting are powder sprayed. In this process, parts are electrostatic sprayed with powder coating and then baked in a high temperature oven.

Other die casting processes and finishes are available upon request.
