Sandblasting｜Homogeneous Matte Surface Solution
Sandblasting is a versatile and highly efficient surface treatment process that cleans and uniformly roughens the surface of workpieces by propelling abrasive media at high speeds. It effectively removes oxide layers, burrs, oil residues, and impurities, creating a fine, uniform matte finish.
Xinling can customize controllable sandblasting solutions tailored to specific material requirements—such as aluminum, stainless steel, and carbon steel—ensuring highly consistent surface finishes across batch-produced workpieces. We support integrated delivery of CNC machining and sandblasting surface treatment, reducing coordination steps, lowering procurement communication costs, and significantly improving overall delivery efficiency.
Application Scenarios

Anodizing｜Solution for high corrosion resistance and appearance enhancement
Anodizing is a specialized surface treatment process for aluminum and aluminum alloys. Through an electrochemical reaction, it creates a dense oxide film on the metal’s surface, significantly enhancing the workpiece’s corrosion resistance, wear resistance, and overall aesthetic quality.
Xinling possesses mature and stable anodizing capabilities. Based on the specific aluminum material and application requirements, we offer customized processes such as standard anodizing and hard anodizing. We support a variety of finish options, including black, silver, and gold, ensuring consistent performance and uniform color. By integrating these services with CNC precision machining for a one-stop solution, we effectively shorten lead times and improve overall production efficiency.
