Product Detail
Custom Powder Coating Services for Sheet Metal Parts
ChunTian provides custom powder coating for sheet metal enclosures, brackets, chassis panels and welded assemblies. Because laser cutting, punching, bending and welding all happen in the same facility, parts move directly into finishing without an extra supplier handoff — visible faces are handled once, and the coating is applied by the same team that built the part.
The pain point: when your finishing is a second factory away
For many B2B buyers, powder coating is the last step of the project — and the easiest one to get wrong. When fabricated parts are shipped out to a separate coating shop, they travel again, get handled again, and are processed by people who never saw your drawing. The problems usually surface at the worst moment: color variation between batches of the same enclosure family, thin or patchy coverage on edges and corners where protection matters most, or powder bridging over threads and mounting holes that nobody masked. One adhesion or appearance failure found at your incoming inspection can stop your assembly, force rework or full recoating, and leave you arguing over responsibility between two suppliers while a delivery date slips.
The procurement impact is real: double freight and repacking, a longer total lead time built from two separate queues, and mixed accountability whenever something goes wrong. For machinery importers and OEM buyers who assemble coated parts into larger systems, a color mismatch between components from different suppliers is visible to your own customer — and it is your brand that takes the complaint.
Our solution: keep finishing inside the fabrication flow. Because coating, inspection and fabrication share one facility and one quality system, edge requirements travel with the drawing, visible faces are protected during handling, and any coating question is answered by the people who can check the part against the original process — not guessed at downstream.
How we apply the coating
- Electrostatic spray: charged powder particles wrap around edges and into recesses, which is exactly where thin coverage and early corrosion start on fabricated sheet metal parts.
- Thermal cure oven: coated parts are cured under controlled oven conditions so the film reaches its specified hardness and adhesion before packing.
- Process-aware masking: holes, threads and grounding points are masked against the drawing before spray, so functional features stay bare and assembly-ready.
- Controlled racking and handling: parts are racked to protect visible faces between fabrication and coating, instead of being shipped loose between two suppliers.
Color, gloss and thickness — confirmed before production
Color is applied to your RAL reference or a customer sample. Gloss level and coating thickness expectations are confirmed at quotation, and coating thickness is controlled per drawing specification rather than left to shop-floor judgment. This is how batch-to-batch consistency is anchored to a written specification instead of an operator's memory.
Quality checks and documentation
Coated parts are checked for appearance, coverage and adhesion against the agreed specification before packing. Inspection records are prepared with the shipment, so what arrives at your dock can be checked against the same standard we used at the line. Production runs under our IATF 16949:2016 certified quality management system, the same system that governs the upstream fabrication steps.
Customization options
- Color: any RAL reference or matched from your physical sample.
- Gloss and texture: specified per drawing and confirmed at quotation.
- Coating thickness: per drawing specification, applied and checked.
- Masking scheme: holes, threads, grounding and contact areas masked per drawing.
- Part range: enclosures, brackets, chassis panels and welded assemblies — coated right after they are fabricated, in the same facility.
Typical applications
- Electrical and equipment enclosures that need a durable, uniform cosmetic finish on visible faces.
- Mounting brackets and structural supports where edge coverage protects against corrosion at the most exposed points.
- Chassis panels and machine housings assembled into larger systems where batch-to-batch color consistency matters.
- Welded frames and fabricated assemblies that would otherwise risk damage and accountability gaps in a second-supplier coating loop.
Frequently asked questions
Can you match a specific color?
Yes. We work from a RAL reference or a physical customer sample. The color, gloss and thickness expectations are confirmed at quotation, before production starts.
Who decides the coating thickness?
The drawing does. Coating thickness is controlled per drawing specification. If your drawing does not state a thickness, we will confirm the expectation with you at quotation so it is written down before the first part is sprayed.
How are threads and mounting holes protected?
Masking is prepared against the drawing before spray. Holes, threads and grounding points that must stay bare are masked, so parts arrive assembly-ready instead of needing rework to clear plugged features.
What inspection do coated parts receive?
Coated parts are checked for appearance, coverage and adhesion against the agreed specification, and inspection records are prepared with the shipment.
Is your quality system certified?
Our production runs under an IATF 16949:2016 certified quality management system. This is a company-level certification that covers the same facility where your parts are fabricated, coated and inspected.
What should I send for a quotation?
Share the drawing or 3D model together with the color reference, gloss level, coating thickness expectations and any masking points. Our team confirms the achievable result and provides a quotation and lead time for your review.
