Die Cast Finishing & Powder Coating
Cast parts often need a finish before they're ready to ship — corrosion protection, cosmetic color, or masked functional surfaces. Our powder coating line runs on-site, immediately after casting and machining.
Typical applications
- Corrosion-protective coatings for outdoor or industrial-environment parts
- Cosmetic color-matched finishes for consumer-facing castings
- Masked coatings that protect machined or threaded surfaces from overspray
Process overview
- 1
Surface prep
Parts are cleaned and prepped appropriate to the alloy and coating system.
- 2
Masking
Custom fixtures and masking protect machined features, threads, and grounding surfaces from coating.
- 3
Powder application & cure
Powder is applied and cured to the specified color and finish.
- 4
Inspection
Coating thickness and coverage are checked against the specification.
Part design considerations
- Which surfaces must remain uncoated (threads, ground contacts, sealing faces) needs to be specified up front
- Color and gloss matching requirements should be confirmed with a physical standard where possible
DFM guidance
- Tell us which features must stay coating-free during quoting so masking/fixturing is built into the process, not added as rework
Quality controls
- Coating thickness verification
- Adhesion testing available on request
Secondary operations available
- Assembly
- Pad printing/decoration after coating
Frequently asked questions
Can you match an existing paint or powder color?
Yes — send a physical color standard where possible for the closest match; we'll confirm before running production quantities.
