Surface Treatment Services
Protect Your Parts. Enhance Performance. Improve Appearance.
At ALTRA PRECISION SDN BHD , we provide professional surface treatment services in Malaysia to enhance the corrosion resistance, wear durability, and visual finish of your metal parts. Whether you're protecting steel from rust, improving adhesion for coatings, or achieving a clean and appealing look — our surface treatment processes ensure that your components are ready for function and presentation.
What is Surface Treatment?
Surface treatment refers to chemical or mechanical processes applied to the exterior of metal parts to improve their performance, durability, or appearance. It is a crucial step, especially for products exposed to moisture, heat, chemicals, or public view.
Our Surface Treatment Capabilities
We offer in-house preparation and coordination with certified vendors for post- processing services, including:
⬛ Deburring & Cleaning – Mechanical removal of sharp edges or burrs after machining or cutting
⬛ Sandblasting / Bead Blasting – Surface texturing and cleaning for paint or coating prep
⬛ Pickling & Passivation – For stainless steel corrosion resistance by removing oxide layers
⬛ Anodizing (Clear / Colour) – For aluminium parts; adds oxidation layer for durability and colour options
⬛ Zinc Plating (Clear / Yellow / Black) – Common for mild steel to prevent rust
⬛ Black Oxide (Bluing) – Aesthetics and corrosion resistance for mild steel
⬛ Powder Coating & Wet Painting – Colour finishing for final products, panels, or casings
⬛ Chemical Conversion Coating (Alodine / Chromate) – Common in aerospa & electronics
All processes follow RoHS-compliant methods when applicable, and finishing certifications can be provided upon request.
