ABS Electroplating Technologies
Hsin Chang specializes in modifying the surface properties of ABS plastic through advanced electroplating. Our process enhances aesthetics, electrical conductivity, wear resistance, and corrosion protection. We offer a full range of ISO-certified finishes from Bright Chrome to RoHS-compliant Trivalent Chrome.
Surface Finishing Capabilities
Bright Chrome
- Process: Multi-layer plating (Copper/Nickel/Chrome).
- Appearance: High-gloss, mirror-like metallic finish.
- Application: Luxury automotive grilles, door handles, and sanitary fittings.
Trivalent Chrome (RoHS Compliant)
- Process: Hexavalent-chromium-free eco-friendly plating.
- Compliance: Fully meets EU RoHS and REACH directives.
- Benefit: Balancing environmental friendliness and product performance, it maintains a bright metallic appearance while delivering excellent corrosion resistance.
Satin / Matte Nickel
- Appearance: Non-reflective, velour, or pearl-like texture (Pearl Nickel).
- Function: Resistant to fingerprints and glare.
- Application: Interior automotive trim and home appliance control knobs.
Brushed Finish (Hairline)
- Definition: A surface treatment technique in which a metal layer is plated onto a plastic substrate, followed by mechanical grinding or brushing to create a unidirectional texture, and finished with a clear coat.
- Effect: Creates a fine, metal-like hairline texture on the plastic surface, enhancing the tactile layering and overall design aesthetics of the product.
Advanced Manufacturing Techniques
- Double-Shot Plating: Utilizes double-injection molding to bond plateable and non-plateable resins, creating precise two-tone components without secondary assembly.
- Selective Plating (Masking): Applies insulating masking to specific areas, allowing for functional non-conductive zones on plated parts (ideal for electronics).
Reliability & Quality Testing
Xinzhuang’s internal laboratory conducts relevant tests in accordance with ISO / ASTM international standards as a reference for evaluating the product’s service life performance under extreme environmental conditions.
| Test Item | Methodology | Purpose |
| CASS Test | Copper-Accelerated Acetic Acid Salt Spray | To verify Corrosion Resistance for harsh environments (e.g., exterior auto parts). |
| Thermal Cycle Test | Cycling between -30°C and 70°C | To ensure plating adhesion under Thermal Stress (no peeling/cracking). |
| Cross-Cut Test | Standard tape adhesion test | To validate the Bond Strength between the metal layer and plastic substrate. |
| Coating Thickness Test | Constant Current Electrolytic Method (Voltage Change Detection) | To verify that the coating thickness meets specification and quality requirements, and to ensure consistency and stability of different metal coatings. |
