Painting Service Supplier In China
Painting is the process of applying a liquid coating of pigmented material to a substrate, which then cures to form a durable and protective solid film. It offers an almost unlimited range of colors and finishes, from matte to high gloss, providing both excellent corrosion protection and superior aesthetic value. As a versatile industrial supplier in China, Celerity Precision offers professional wet painting services for machined and fabricated parts. We deliver components with a high-quality, decorative finish that meets your exact color and texture specifications.
For a flawless, durable, and color-matched painted finish on your custom parts, partner with the integrated capabilities of Celerity Precision.
Your Painting Finish Manufacturer
At Celerity Precision, we are a manufacturer that treats painting as a critical final step in the production process. Our dedicated finishing department includes a climate-controlled spray booth and curing ovens to ensure a clean, dust-free application and proper coating adhesion. Our process starts with meticulous surface preparation, which may include degreasing, sanding, or applying a chemical primer like Alodine to ensure the paint forms a robust, permanent bond with the substrate. Our skilled technicians expertly apply the paint to a consistent thickness, preventing runs, sags, and other imperfections.
By managing both the precision fabrication and the painting in-house, we offer a truly single-source solution. This eliminates the common problem of a machinist blaming the painter (and vice versa) for any imperfections. We take full responsibility for the final product. We understand the importance of masking threads, mating surfaces, and other critical features, and we have the expertise to execute this flawlessly. Choose Celerity Precision to manufacture parts that are not only accurately made but are also professionally painted and ready for your final assembly line.
Ensure your parts look as good as they perform. Upload your project to Celerity Precision for a single, accountable quote on fully finished components.
Painting: Technical Specifications
| Feature | Description |
| Surface Roughness (Ra) | Covers Substrate. The final texture is determined by the paint system (primer, paint, clear coat), not the underlying material. It can be specified from matte (non-reflective) to high gloss (mirror-like). |
| Applicable Materials | Universal. Can be applied to virtually any material we work with, including all metals (Aluminum, Steel, etc.) and all plastics. Proper surface preparation and primer selection are key to adhesion. |
| Cosmetic Availability | Superior. Offers the widest possible range of colors (RAL, Pantone matching), sheens (matte, satin, gloss), and textures (smooth, textured, wrinkle). The ultimate choice for decorative finishes. |
| Visual Appearance | A uniform, opaque, solid-colored layer. The appearance is defined by the specified color and gloss level, from a flat, non-reflective look to a smooth, shiny, and highly polished surface. |
Advantages of Painting Surface Finish
Unlimited Color and Finish Options
Provides an unmatched range of colors (matched to RAL or Pantone standards), textures, and gloss levels for complete design freedom.
Excellent Corrosion Protection
A properly applied paint system with a suitable primer creates a very effective barrier against moisture and environmental corrosion.
Applicable to All Materials
One of the few finishing processes that can be effectively applied to both metals and plastics with equal success.
Cost-Effective for All Volumes
Painting is an economical finishing solution suitable for everything from one-off prototypes to large-scale production runs.
Masking and Multi-Color Applications
Allows for precise masking to create complex, multi-colored designs, logos, and lettering on a single part.
Can Hide Minor Surface Imperfections
The use of high-build primers can help to fill and conceal minor scratches or imperfections in the substrate material.
Painting Design Considerations
Coating Thickness
Paint adds a measurable thickness (typically 0.05mm - 0.15mm depending on the system). This buildup must be accounted for in the design of tight-fitting assemblies, and internal features like holes will become smaller.
Masking is Essential
Any threads, mating surfaces, or areas that must remain free of paint need to be clearly identified on the drawing for masking.
Line of Sight Process
As a spray-applied finish, it is a line-of-sight process. Deep internal cavities or channels may be difficult or impossible to coat uniformly.
Sharp Edges
Paint tends to pull away from sharp external edges during curing, resulting in a very thin, less durable coating at these points. A small radius on corners is highly recommended for better durability.
FAQ
What is the difference between painting and powder coating?
Painting applies a liquid coating that cures chemically or through evaporation. Powder coating applies a dry powder electrostatically, which is then melted and cured in an oven, typically resulting in a tougher, more durable finish.
Can you match a specific RAL or Pantone color?
Yes. We can source paint to match any standard color code, which is a primary advantage of this process. Please provide the color code with your RFQ.
How durable is industrial paint?
Industrial-grade paints (like two-component epoxies or polyurethanes) are very durable and resistant to chemicals, abrasion, and UV exposure. Durability is highly dependent on proper surface preparation and the type of paint used.
How much thickness does painting add?
A typical industrial paint system (primer + topcoat) will add between 0.05mm and 0.15mm (0.002″ – 0.006″) to the surface.
Do you prepare the surface before painting?
Absolutely. Surface preparation is the most critical step. Our process always includes thorough degreasing and may include sanding, blasting, or a chemical primer to ensure maximum adhesion.
Can you paint plastic parts?
Yes, we are experienced in painting a wide variety of plastics. This requires special adhesion promoters and flexible paints, which are part of our standard process for plastic substrates.
What kind of gloss levels can you provide?
We can provide a full range, typically specified as matte (0-10% gloss), satin (20-40% gloss), semi-gloss (50-70% gloss), or high gloss (80%+ gloss).
Can you create a textured finish?
Yes, specific texturing agents can be added to the paint to create a variety of finishes, from a fine, sandy texture to a heavy-duty wrinkle finish.
Do I need to worry about my threaded holes?
No. Our standard practice is to meticulously plug and mask all threaded holes and critical features before any paint is applied.
How should I specify painting on my drawing?
Be as specific as possible. The ideal note would be: “Finish: Paint. Color: RAL 7035. Gloss: Satin. Apply primer for aluminum.” If you just specify “Paint, Black,” we will use a standard industrial black satin paint.
