Surface Finishing: A Value-Boosting Process in Plastic Injection Molding
In today’s competitive market, surface finishing has become an essential value-added step in the plastic injection molding process. To enhance product appearance and reinforce brand identity, many customers choose various post-processing techniques for their custom plastic parts.
Popular options include spray painting, powder coating, water and vacuum electroplating, laser engraving, silk-screen printing, and logo inlay coloring. These finishing methods not only improve aesthetics but also provide added functionality—such as scratch resistance, anti-fingerprint properties, conductivity, and UV protection.

Why Surface Finishing Matters:
1. Elevates product quality and market competitiveness
2. Reinforces brand recognition and visual appeal
3. Expands product utility and application scenarios

Different plastic materials (like ABS, PC, PA, PP) are compatible with specialized finishes, including:

• Industrial-grade wear-resistant coatings (for heat and oil resistance)
• Matte textures (for handheld comfort)
• High-gloss metallic or leather-like coatings (ideal for product housings)
