Surface Treatment
At Rishi Laser, fabricated assemblies undergo thorough Surface Treatment before coating to ensure strong adhesion and long-lasting finishes. Surfaces are cleaned of impurities, rust, and oils that can hinder protective coatings using advanced methods like shot blasting, sandblasting, and liquid dipping.
Sandblasting propels fine sand particles at high velocity to remove rust and oil, creating a clean surface ready for coating.
Pre-treatment with seven-tank cleaning removes grease and heavy oxides chemically, leaving a rust-free surface and improving paint adhesion. Our modern facilities for shot blasting and chemical pre-treatment ensure that every part is prepared for high-quality powder coating, epoxy painting, or zinc plating, delivering durable and smooth finishes for all sheet metal assemblies.

Manufacturing FAQ:
Precision & Support
What types of surface finishing do you offer?
We provide 7-tank pre-treatment, powder coating, liquid painting, and epoxy coating in-house.
Why is the '7-tank process' important?
It ensures that the metal is chemically cleaned and phosphated, providing a superior bond for paint and preventing long-term rust.
Do you have an in-house powder coating plant?
Yes, we have complete in-house lines with baking ovens to ensure a durable, industrial-grade finish.
Can you match specific RAL color codes?
Yes, we can match any standard RAL or Pantone color required by your brand’s specifications.
Do you provide shot blasting services?
Yes, we use shot blasting to remove scales and impurities from heavy plates before painting or welding.
How do you test the quality of the paint?
We perform Adhesion tests, Cross-cut tests, and DFT (Dry Film Thickness) measurements to ensure the coating meets OEM standards.
Can you handle very large parts for painting?
Yes, our paint booths and ovens are designed to accommodate large structural assemblies up to 4 meters in length.
