Improve appearance, adhesion & performance of plastic components
Plastic Surface Treatment Services for Custom Plastic Parts
Plastic surface treatment plays a critical role in enhancing the appearance, functionality, and durability of custom plastic parts. At SzCrealink, we provide professional plastic surface treatment services designed to improve surface adhesion, wettability, wear resistance, and visual quality.
Whether your plastic parts require better bonding for painting and printing, improved surface energy, or a refined aesthetic finish, we help you select the right surface treatment process based on material type and end-use requirements.
Why Plastic Surface Treatment Matters?
Many plastics have naturally low surface energy, which makes painting, printing, bonding, or coating difficult without proper preparation. Surface treatment modifies the outer layer of plastic parts to ensure reliable performance in real-world applications.
Benefits of plastic surface treatment include:
•Improved adhesion for painting, coating, and gluing
•Enhanced surface wettability and ink adhesion
•Better resistance to wear and environmental exposure
•Upgraded appearance from matte to high-gloss finishes
•Higher product consistency and perceived value
Common Plastic Surface Treatment Methods
We offer a wide range of plastic surface treatment methods, selected according to plastic type, part geometry, and functional needs.
Plasma Surface Treatment
Plasma surface treatment modifies the plastic surface at a molecular level to increase surface energy and improve adhesion. It is widely used as a preparation step before painting, printing, or bonding.
Best for: ABS, PC, PP, PE, medical and electronic components
Corona Treatment
Corona treatment is commonly used for plastic films and thin plastic surfaces. It improves surface wettability and ink adhesion through controlled electrical discharge.
Best for: Plastic films, packaging materials, labeling applications
Flame Surface Treatment
Flame treatment briefly exposes the plastic surface to controlled heat, increasing surface energy and improving bonding performance.
Best for: PP, PE, large plastic housings, automotive components
Chemical & Mechanical Surface Treatment
Coating, Painting & UV Cured Finishing
Electroplating on Plastics
Applications: Decorative trim, automotive parts, branded components
Laser Marking & Printing
Includes:
•Laser engraving
•Screen printing
•Pad printing
•Thermal transfer printing
| Method | What It Does | Best For |
|---|---|---|
| Polishing | Adds gloss, removes surface defects | Decorative parts, optical use |
| Texturing / Etching | Adds grip or visual texture | Housings, handles, tool parts |
| Painting / Coating | Custom colors, protection | Consumer products, toys |
| Electroplating | Metal-like finish, corrosion resistance | Automotive parts, trim |
| Plasma Treatment | Improves adhesion | Painting, gluing, printing prep |
| Laser Etching | Permanent marking & branding | Logos, serial numbers, patterns |
Tip: The right treatment depends on the plastic. For example, ABS is great for electroplating, but PP may need plasma prep first.
Plastic Materials We Support
Different plastics respond differently to surface treatment. Our engineers help match materials with the right process.
•ABS plastic surface treatment – ideal for painting, plating, and printing
•Polycarbonate (PC) – suitable for high-gloss and protective coatings
•PP / PE – requires plasma, corona, or flame treatment
•PA / POM – functional surface finishes for wear resistance
•Plastic films – corona treatment and surface activation
