When sourcing ABS plastic plating, you must prioritize material grade, specifically plating-grade ABS (e.g., ABS 727 or 757), which contains butadiene spheres that allow for proper etching. The plating thickness is critical; standard decorative chrome usually requires 10-20 microns of Nickel and 0.25-0.5 microns of Chrome. Ensure the supplier uses a palladium-based activation process to guarantee strong adhesion between the plastic substrate and the metal layers, preventing peeling or blistering.
