Why Sino Die Casting Leads in Surface Treatment Innovation

In-House Lab for Accelerated Durability Testing

Salt spray chambers (500–2,000 hours), UV aging testers, and cross-cut adhesion equipment validate coatings before production. For a telecom client, we identified a flaw in a competitor’s anodizing process, preventing potential $2M in field failures.

At Sino Die Casting, a leading high - tech enterprise in Shenzhen since 2008, surface treatment is an integral part of our comprehensive service offering. We specialize in high - precision mould manufacturing, die casting, CNC machining, and custom part production, and surface treatment plays a vital role in enhancing the quality of these products. Our surface treatment services are designed to cater to the diverse needs of industries such as automotive, new energy, robotics, and telecommunications. With ISO 9001 certification, we adhere to strict quality control measures. We offer a wide range of surface treatment options, including but not limited to anodizing, plating, and powder coating. Anodizing can provide a hard, corrosion - resistant layer on aluminum parts, which is essential for automotive and telecommunications components exposed to the elements. Plating can enhance the appearance and conductivity of metal parts, while powder coating offers a durable and attractive finish. Our team of experts carefully selects the appropriate surface treatment method based on the part's material, intended use, and customer requirements. We ensure that the surface treatment process is carried out with precision, resulting in components that have improved functionality, longer lifespan, and an appealing look, making us a flexible and reliable partner for our global clients.

Frequently Asked Questions

What surface treatments do you recommend for outdoor telecom equipment?

For outdoor enclosures, we prioritize polyester powder coating (120–150μm thickness) with UV stabilizers, offering 1,000+ hours of salt spray resistance. For coastal installations, we add a secondary epoxy primer layer to prevent rust.
