Surface finish
Spraying for CNC & Molded Parts
Spraying applies a thin, even coat of paint or clear finish using air or airless systems.
- Even thin films on large or complex parts.
- Ideal for primers, clear coats, and touch-ups.
Surface finish
Spraying applies a thin, even coat of paint or clear finish using air or airless systems.
What it is
Spraying is the method of applying liquid coatings with a spray gun. Air, airless, or HVLP systems atomize the paint into fine droplets that land evenly on the part. It is used for primers, clear coats, and finishes where a thin, smooth film is needed.
How it works
Prep & mask
We clean, sand, and mask no-spray zones.
Set up gun
We pick pressure and tip for the coating.
Spray passes
Even overlapping passes build a uniform film.
Flash & cure
The coating flashes off and dries or bakes.
Why choose it
Great for primers and clear coats.
Few brush marks or streaks.
Handles big and irregular parts.
Works with many liquid coatings.
Typical specs
| Specification | Typical range / value | Notes |
|---|---|---|
| Methods | HVLP, airless, conventional, electrostatic | |
| Film thickness | 10 – 60 µm per coat | |
| Coatings | Primer, enamel, urethane, clear | |
| Base materials | Metal, plastic, wood, composite |
Best applications
Base layer before topcoat.
Gloss and protection over color.
Large frames and panels.
Spot repair of finished parts.
Materials
We apply Spraying to the materials below. Not sure if your material qualifies? Our engineers will confirm it for free.
Our solution
We spray primers, clears, and finishes with the right gun and method for your part. We control film build to avoid runs and orange peel.
Design tips
Several passes beat one heavy coat.
Overspray reaches nearby areas.
A primer improves adhesion and life.
