Powder Coating Service
Powder coating support for OEM metal parts requiring durable surface protection, stable appearance, corrosion resistance and controlled packaging.
Automatic and manual options.
Customer-specified brands.
Thickness, adhesion and color.
Engineering Recommendation
Choose powder coating when durability and repeatable batch finish are important.
Powder coating is usually recommended for brackets, cabinets, enclosures, frames and outdoor metal parts that need a durable protective finish.
NBFEIYU can review whether automatic line coating or manual coating is more suitable based on part size, geometry, visible surfaces, annual volume, color requirements and target cost. Customers can also specify powder brands such as Tiger or other approved suppliers when required.
Finish Decision Guide
When should buyers choose powder coating?
Surface treatment is selected by application environment, appearance standard, corrosion risk, coating durability, assembly requirements and target cost.
| Finish Route | Choose When | Do Not Choose When | Common Parts |
|---|---|---|---|
| Powder Coating | Durable coating, good coverage and repeat batch finish are needed. | Very thin coating, high-temperature service or local wet-paint repair is required. | Frames, cabinets, enclosures, brackets. |
| Painting | Special color appearance, thin coating or touch-up flexibility is needed. | Thicker durable batch coating is preferred. | Covers, visible panels, housings. |
| Anodizing | Aluminum parts need metallic corrosion-resistant finish. | Steel parts or opaque coating is needed. | Aluminum CNC parts and profiles. |
| Passivation | Stainless steel corrosion resistance needs improvement without color coating. | Colored appearance or thick protective coating is required. | Stainless steel hardware, marine parts. |
Buyer Control Points
Automatic line, manual line and powder selection are reviewed before production.
The best coating route depends on part size, hanging method, coating area, color, powder type, visible surface, masking and packaging requirements.
Inspection Evidence
Appearance, adhesion, thickness and packaging checks before shipment.
Design & RFQ Guidelines
What should buyers confirm before quotation?
Finish quality depends on material, pretreatment, color standard, visible surface grade, coating thickness, masking areas, packaging and expected service environment.
Powder Brand
Customers may specify Tiger or other approved powder suppliers when project standards require it.
Coating Thickness
Define coating thickness range or acceptance standard before production.
Hanging Points
Confirm where hanging marks are acceptable, especially on visible surfaces.
Masking Areas
Threads, holes, grounding points and assembly faces should be marked clearly.
Curing
Part material and geometry should tolerate curing temperature without deformation risk.
Packaging
Specify scratch prevention, separators and export packing for coated parts.
Quality Control
Powder coating inspection for OEM metal parts.
Powder coating quality is checked for appearance, color consistency, coating thickness, adhesion, curing condition, salt spray requirement and packaging protection.
Visual appearance inspection
Checked according to approved sample, drawing requirements and shipment standard.
Coating thickness measurement
Checked according to approved sample, drawing requirements and shipment standard.
Color consistency check
Checked according to approved sample, drawing requirements and shipment standard.
Adhesion test when required
Checked according to approved sample, drawing requirements and shipment standard.
Salt spray test when required
Checked according to approved sample, drawing requirements and shipment standard.
Packaging inspection before shipment
Checked according to approved sample, drawing requirements and shipment standard.
FAQ
Powder Coating Service FAQ for OEM buyers.
Do you have automatic and manual powder coating lines?
Yes. The coating route can be selected according to part size, geometry, coating area, annual volume and finish requirements.
Can customers specify powder brands?
Yes. Customers can specify Tiger or other approved powder suppliers when required by project standards.
When should I choose powder coating?
Choose powder coating for durable protective finish, consistent batch appearance and corrosion resistance on metal brackets, frames, enclosures and cabinets.
When is painting better than powder coating?
Painting may be better for thin coating, special appearance, local repair or project-specific wet-paint requirements.
What should I send for quotation?
Send drawing, material, quantity, color, powder brand if specified, coating thickness, masking areas, application environment and packaging requirements.
Can powder coated parts be used outdoors?
Yes, when pretreatment, powder type and inspection requirements match the exposure environment.
How do you inspect powder coated parts?
We check appearance, color consistency, coating thickness, adhesion when required, curing quality and packaging protection.
Can powder coating be combined with welding or bending?
Yes. Powder coating is commonly applied after laser cutting, bending, welding, grinding, cleaning and pretreatment.
