WHAT CAN WE DO

Keywin offers end-to-end precision manufacturing capabilities across multiple processes, including CNC milling, CNC turning, turn-mill compound machining, and advanced 5-axis machining—enabling efficient production of everything from high-precision metal components to complex structural parts.

At the same time, we operate a well-established in-house capability and a certified partner network covering forging, sheet metal fabrication, injection molding, die casting, and sand casting. This allows us to flexibly select the most suitable manufacturing route based on material properties and part geometry. We also provide a full range of surface finishing solutions, including anodizing, powder coating, bead blasting, polishing, black oxide, and plating, ensuring that every product meets the required standards for appearance, corrosion resistance, and functional performance.

With this integrated manufacturing ecosystem, Keywin reliably delivers end-to-end production services—from rapid prototyping and small-batch trials to full-scale mass production—for customers worldwide.

Surface Finishing Capabilities

Keywin offers a variety of surface finishing processes to enhance the appearance, durability, corrosion resistance, and overall performance of your parts.

Available processes: Black anodizing, powder coating, plating, polishing, nickel plating, sand blasting, laser marking, electrophoresis (E-coating) and more. These finishing options are suitable for aluminum, steel, stainless steel, brass, and other metal alloys, meeting both functional and aesthetic requirements.

If you require additional surface finishing processes, please feel free to contact us — we will recommend the most suitable solution based on your product needs.
