  • Complete Surface Finishing Solutions

    At Wometal, we provide comprehensive surface finishing services for aluminum and stainless-steel parts produced by our in-house CNC machining and die casting lines.
    By integrating these processes under one roof, we ensure each part receives a consistent finish — from precision machining to final coating — with tight control over quality and color.

    Our finishing capabilities include:

    • Anodizing (Type II / Type III) – corrosion resistance and color stability for visible components
    • Powder Coating – durable, uniform coating for harsh environments
    • Polishing – brushed or mirror surface for premium appearance
    • Bead Blasting – smooth matte texture for a refined feel
    • Laser Marking & Branding – add custom logos or part numbers

    Every finished component is fully inspected for adhesion, color, and surface texture before shipment, ensuring it meets both engineering and aesthetic requirements for automotive and EV applications.

  • Finishing Processes

    anodizing aluminum surface finishing process for automotive components

    Anodizing (Type II / III)

    Color-stable, corrosion-resistant, suitable for visible parts.
    Colors: black, clear, red, blue, gold (custom on request).

  • Consistency & Quality Control

    At Wometal, surface quality isn’t treated as a final step — it’s built into every stage of production.
    From die casting to CNC machining and final finishing, all processes are managed under one quality system to ensure dimensional accuracy, coating thickness, and color consistency across every batch.

    We perform:

    • Adhesion and hardness testing for anodized and coated surfaces
    • Color and gloss measurement to ensure visual uniformity
    • CMM and dimensional verification from our CNC machining inspection data
    • Surface roughness checks (Ra ≤ 0.4 μm typical)
    • Batch traceability and process records for full production visibility

    This integrated quality approach ensures that every part — whether cast, machined, or finished — meets the high standards required for automotive, EV, and industrial applications.

  • Industries We Serve

    Our surface finishing services support a wide range of applications — from visible aluminum trims in cars to durable, color-stable components for electric vehicles and motorcycles.

  • What’s the Difference Between Anodizing and Powder Coating?

    Anodizing changes the aluminum surface at a micro-structure level, keeping a metallic look and improving corrosion resistance. Powder coating adds a thicker protective layer with strong color coverage and chip resistance. We’ll recommend the best option based on your part geometry, application and budget.
