Premium Liquid Spray Painting & CMF Solutions
Liquid Spray Painting is the most versatile finishing method for adding color, texture, and value to manufactured parts. Unlike powder coating which is limited to metals, wet painting can be applied to virtually any substrate—including plastics (ABS, PC, Nylon), metals, and composites. It is the key to achieving specific brand colors and premium tactile experiences.
At JUCHENG, we treat painting as a critical engineering step. Our facility features Class 10,000 dust-free spray booths and a dedicated color lab. Whether you need a "Piano Black" high-gloss finish for a display prototype, a rubberized "Soft-Touch" coating for a handheld device, or functional EMI Shielding for electronics, our master painters deliver showroom-quality results that elevate your product's perceived value.

JUCHENG’s Painting & Finishing Capabilities
We offer a full spectrum of cosmetic and functional coatings:
- Color Matching: We precisely match colors to Pantone (PMS), RAL, or physical color chips using spectrophotometers, ensuring your brand identity is consistent.
- Texture Variety: From High Gloss (Wet look) and Satin to Dead Matte and Splatter/Texture finishes that simulate mold texturing (VDI standards).
- Soft-Touch: A rubberized coating that gives hard plastic a velvety, warm feel.
- EMI/RFI Shielding: Conductive copper or nickel paints applied to the interior of housings to block electromagnetic interference.
- UV Clear Coats: Hard-wearing clear coats (Gloss or Matte) to protect prints and prevent scratching or yellowing.

Substrates We Paint
We formulate specific primer and paint combinations for different materials to ensure adhesion (Cross-Hatch Test pass):
| Material Class | Preparation Required | Common Finishes |
| Plastics (ABS, PC, PC/ABS) | Best. Needs minimal prep. Adhesion is excellent. | Color matching, Soft-Touch, High Gloss. |
| Nylon (PA) / POM | Difficult. Requires flame treatment or specialized primers due to chemical resistance. | Textured functional coatings. |
| 3D Printed Parts (SLA/SLS) | Heavy Prep. Requires sanding and high-build primer to fill layer lines. | Smooth cosmetic finish hiding all print marks. |
| Metals (Al, Steel) | Requires degreasing and acid etching wash primers. | Automotive grade enamels, clear coats over polish. |
| Composite (Carbon Fiber) | Requires clear coating to seal porosity and block UV. | High gloss clear to show weave. |

| Tactile Feel | Variable (Soft/Gloss/Matte) | Hard / Textured | Hard plastic feel |
| Cosmetic Quality | Highest (Class A) | Industrial / Durable | Good (May show flow lines) |
| Cost | Medium | Low | Lowest (High volume) |
Why Choose Us
- Dust-Free Environment: Dust is the enemy of a perfect finish. We paint in controlled clean rooms with positive pressure to prevent specks and inclusions.
- Adhesion Guarantee: We perform ASTM D3359 cross-cut adhesion tests on sample coupons for every batch to ensure the paint won't peel.
- Masking Expertise: We use die-cut masking tapes and custom fixtures to paint complex multi-color patterns or keep specific areas (like glue tracks) paint-free.
- Prototype to Production: We handle single-unit prototypes with the same care as 1,000-unit low-volume production runs.
Advantages
- Hide Defects: Painting covers machining marks, 3D printing layers, and material inconsistencies, unifying the look of an assembly made from different materials.
- Brand Identity: Achieve the exact specific color that defines your brand, which might not be available in raw material stock.
- Functionality: Add properties the base material lacks, such as UV resistance, electrical conductivity (Shielding), or non-slip grip (Soft-touch).
Industries Served
- Consumer Electronics: Headphones, smart home devices, gaming peripherals (Cosmetic perfection).
- Automotive: Interior trim components, dashboard buttons, exterior mirror caps.
- Medical: Diagnostic device enclosures (Clean, chemical resistant).
- Appliances: High-end coffee machines, blenders (Metallic looks).
- Aerospace: Interior cabin parts requiring fire-retardant coatings.
