Thermal Spraying for CNC & Molded Parts
Thermal spraying melts coating material and sprays it onto a part. It builds thick, tough wear and repair layers.
- Thick coatings for wear, heat, or repair.
- Restores undersized or worn parts.
Surface finish
Thermal spraying melts coating material and sprays it onto a part. It builds thick, tough wear and repair layers.
What it is
Thermal spraying heats a wire or powder until it melts, then sprays it onto the part with gas. The droplets flatten and bond as a coating. Methods include flame, arc, plasma, and HVOF. It builds thick layers of metal, ceramic, or carbide for wear, heat, or repair.
How it works
Prep & roughen
We clean and grit-blast for bonding.
Feed material
Wire or powder is fed into the torch.
Heat & spray
The material melts and is sprayed onto the part.
Build & finish
Layers build up, then we machine or grind if needed.
Why choose it
Carbide and ceramic layers fight abrasion.
Ceramic coatings survive high heat.
Restores worn or undersized parts.
Alloy coatings block rust and chemicals.

Materials
We apply Thermal Spraying to the materials below. Not sure if your material qualifies? Our engineers will confirm it for free.
Our solution
We thermal spray metal, ceramic, and carbide coatings for wear, heat, and repair. We finish by grinding to your dimension.
Design tips
Best when you need mm-scale layers.
We grind to final size after spraying.
HVOF for density, plasma for ceramics.
