Powder Coating Services: Tough, Uniform Finishes
Powder coating electrostatically sprays a dry polymer powder onto a part and bakes it into a tough, uniform, solvent-free finish. For durable color on metal, it beats liquid paint on chip resistance and environmental footprint. This guide covers how it works, when to choose it, the materials, and how to spec your job.
How Powder Coating Works
A charged powder sticks to the grounded part, then cures in an oven into a continuous film. We usually prep by sandblasting and form the part by CNC bending first.
Powder vs. Wet Painting
Powder is tougher and has no VOC; wet painting handles thinner films and special substrates. Choose powder for durability and color range.
Materials We Powder-Coat
- Steel and aluminum—the standard substrates.
- Stainless—for color on corrosion parts.
- Some castings—with proper prep.
Industries That Rely on Powder Coating
Appliances, architecture, machinery, and furniture all use powder coat for durable color.
How to Spec Your Powder Coating Job
- Choose color and gloss (RAL or custom).
- Define film thickness (typical 60–80 µm).
- Specify pretreatment (phosphate, blast).
- Note cure limit for heat-sensitive parts.
- Flag masking of threads/features.
- Share volume for line efficiency.
FAQ
How tough is it?
Very—resists chips and scratches far better than paint.
Is it eco-friendly?
Yes—no solvent VOCs.
Can threads be coated?
We mask them; coating would bind.
