Spray Painted Car Trim

Customizable Spray Painted Plastic Parts with Enhanced Surface Quality and Visual Impact

Design & Mold Preparation

• Our engineering team prepares 3D CAD models and technical drawings or customers provide.
• Factory manufactures high-precision injection molds using CNC machining and EDM processes.

Plastic Injection Molding

• Selects the appropriate plastic material.
• The molding system injects molten plastic into the molds under controlled temperature and pressure.
• Molds cool and release the finished parts.

Surface Preparation

• Remove burrs and flash from molded parts.
• Clean surfaces to eliminate dust, oils, and residues.
• Apply primer or sanding treatment for better paint adhesion.

Spray Painting / Coating

• Coating line applies the base coat, color coat, and protective topcoat using controlled spray systems.
• The process produces finishes such as gloss, matte, satin, textured, metallic, or multi-color effects.
• Coating under controlled temperature and humidity.

Quality Inspection

• Inspect surface uniformity, color consistency, and adhesion.
• Check dimensions and mechanical fit in assembly channels.

Secondary Processes

• Add silk-screened logos, labels, or decals.
• Apply protective films or additional UV/topcoat layers if needed.

Packaging & Delivery

• Carefully package finished enclosures to avoid scratches or damage.
• Ready for shipment or assembly integration.

We offer a full range of coating options for plastic housings, including RAL-matched and Pantone-matched colors, as well as PU, acrylic, and protective varnish systems.

Multiple surface effects and textures are available-gloss, matte, satin, smooth, textured finishes, "water-drop" patterns, Nextel-style velvet coatings, and self-graining surfaces-allowing your plastic enclosures to achieve both functional protection and premium visual appeal.

Compared with uncoated plastic parts, spray-painted protective enclosures offer several notable benefits:

• Coating improves appearance. It creates uniform color, a smooth surface, and a premium look.
• Painted surface increases durability. The coating resists scratches, abrasion, and minor impacts.
• Coating can protect the enclosure from the environment. It helps block UV exposure, moisture, and dust. This protection extends product service life.
• Process allows flexible surface finishes. Manufacturers can achieve gloss, matte, textured, metallic, or multi-color effects. These finishes support brand identity.
• Controlled spray-painting processes ensure consistent quality. Every part meets defined color and surface standards.
• The finished enclosures integrate easily into products. Common uses include electronic housings, consumer devices, lighting products, and other plastic enclosures.
