Broad color range
Custom and standard colors can be reviewed against codes or physical samples.
Coating
Painting for Custom Manufactured Parts
A liquid coating option for controlled color, gloss, texture, and appearance on metal or selected plastic parts.
- Color matching support
- Appearance control
- Multiple gloss levels
Finish overview
Flexible color and appearance control across compatible substrates.
Painting is used for prototype shells, molded plastic housings, metal covers, bezels, and display models that need a controlled color, gloss, texture, or branded appearance. Primers and topcoats can be selected around the substrate and service environment.
Paint quality depends on cleaning, surface energy, primer compatibility, masking, film build, cure, and handling. The specified color is only one part of the system; adhesion and wear expectations should also be defined.
Appearance
What the finished surface can look and feel like.
Gloss control
Matte, satin, and gloss systems change perceived color and reveal different levels of surface preparation.
Layered coverage
Primer, color, and optional clear coat combine to create the final appearance and film build.
Suitable processes
Manufacturing routes commonly paired with this finish.
Suitable materials
Base materials that require process-specific review.
Typical applications
Part families commonly reviewed for painting.
Prototype housings
Electronic bezels
Display models
Instrument covers
Branded equipment panels
Low-volume appearance parts
Benefits
Where this option can add value.
- Supports custom color and gloss
- Can cover different compatible substrates in one product
- Allows primer and clear-coat systems
- Works for prototypes and low-volume appearance development
Limitations
Requirements that need engineering review.
- Adhesion varies with plastic grade and surface preparation.
- Film build affects tight fits and fine text.
- Paint can chip or scratch under impact and assembly loads.
- Color approval on a screen does not replace a physical sample.

FAQ
Painting questions from engineering and sourcing teams.
Can molded plastic parts be painted?
Yes, when the resin, mold-release condition, cleaning, primer, and coating system are compatible. Adhesion and cosmetic trials should use production-representative parts.
What is needed for paint color matching?
Provide a recognized color reference and preferably a physical approved sample with the required gloss and texture. Substrate color also influences the result.
Can paint be kept out of snap fits and threads?
Yes, controlled masking can protect selected features. The no-paint zones and acceptable witness lines should be shown on the drawing.
