Powder Coating Services with RAL Color Control
Powder coating for enclosures, covers and frames: RAL color by number, 60 to 120 micrometer film, masked precision features, adhesion and thickness verified per batch.
Powder Coating for Enclosures and Covers
Powder coating gives thick, even, weather-stable color with good edge coverage, which is why it is the default on enclosures, panels and frames. KGL runs powder through audited partner lines, with masking callouts, RAL agreement and batch adhesion checks controlled from our side. Salt spray validation available where the drawing or the market demands it.
When to Choose It
| Part | System | Notes |
|---|---|---|
| Outdoor enclosures and panels | Polyester powder, UV stable | 60 to 120 μm |
| Machine frames and covers | Epoxy-polyester mix | good edge coverage |
| Consumer-visible parts | Fine texture or gloss, RAL agreed | face map plus sample |
| Electrical housings with grounding | Powder with masked grounding points | masking per drawing |
Specifications We Control
| Item | Specification |
|---|---|
| Colors | RAL catalog, gloss or fine texture, agreed by number and retained sample |
| Film thickness | 60 to 120 μm typical, measured per batch |
| Verification | Cross-hatch adhesion, thickness map, salt spray on request |
| Masking | Threads, grounding, mating faces plugged or taped per drawing |
| Compliance | RoHS compatible; declarations per shipment |
| Lead time | 2 to 4 working days added to the route |
How We Run It and Check It
Pre-coat decisions we make at quote time: which faces are cosmetic, which features get masked, and whether sheet metal edges need a pre-finish so the powder does not telegraph laser-cut burrs. Parts come back to KGL for a final appearance check against the face map before packing with the certificate.
Related capability: sheet metal fabrication for the enclosures this finish usually lives on. Aluminum alternative: anodizing.
Cross entrances: by material | CNC machining | inspection and QC.
Frequently Asked Questions
Which RAL colors can you hold?
Any RAL in the standard powder catalog, plus texture and fine-texture finishes. Color is agreed by RAL number on the quote; for visible consumer parts we agree a face map and retained sample before production.
How does powder coating affect tolerances?
Film builds 60 to 120 micrometers typical, so it is a finishing route for cosmetic and protective surfaces, not for precision fits. Threads, grounding points and mating faces are masked per drawing, and edge buildup at corners is planned into the callout.
Powder coat or anodize for an aluminum enclosure?
Powder wins on thick, weather-exposed, colored surfaces and on edge coverage. Anodize wins where the surface must stay hard and thin and where dimensions matter. Enclosures often use both: powder outside, masked and clear anodized or bare at mounting and grounding features.
What testing do you provide?
Cross-hatch adhesion per batch on witness panels, film thickness measurement, and salt spray on request. Reports travel with the shipment.
