Surface finish
Chemical Plating for CNC & Molded Parts
Chemical plating deposits metal without electricity. It gives an even coat on complex shapes and inside holes.
- Uniform thickness, even on complex geometry.
- No electrical contact needed.
Surface finish
Chemical plating deposits metal without electricity. It gives an even coat on complex shapes and inside holes.
What it is
Chemical plating (also called electroless deposition) uses a chemical reaction to plate metal onto a part. No electric current is needed. Because there is no current, the coating is very even across the whole surface, including recesses and internal bores.
How it works
Clean & activate
We remove oil and oxides and activate the surface.
Catalyze
A catalyst prepares the surface to accept deposition.
Immersion in bath
The chemical bath deposits metal autocatalytically.
Rinse & inspect
We rinse, measure thickness, and inspect.
Why choose it
Uniform thickness on complex shapes.
Seals the base metal from rust.
Deposited alloys are hard and low-friction.
Plates non-conductors after seeding.
Typical specs
| Specification | Typical range / value | Notes |
