Our Dual-Chamber DC Magnetron Sputtering System is a state-of-the-art physical vapor deposition (PVD) solution designed specifically for metallizing plastic substrates. With two independent vacuum chambers, it delivers high throughput, exceptional coating uniformity, and the flexibility to coat a wide range of metals onto ABS, PP, PC, PVC, and other engineering plastics. Ideal for applications requiring food-grade safety – such as disposable cutlery, tableware, and food packaging – this system combines productivity with uncompromised hygiene standards.
Features
Dual-Chamber Design
Two separate vacuum chambers allow simultaneous or alternating coating processes. While one chamber is in production, the other can be loaded/unloaded, minimizing downtime and doubling output compared to single-chamber systems.
DC Magnetron Sputtering Technology
High-energy metal ions are ejected from a target cathode and deposited onto plastic surfaces at low temperatures.
Excellent adhesion without damaging heat-sensitive plastics (PP, ABS, PVC, PC).
Smooth, pinhole-free metallic films with controllable thickness.
Wide Metal Compatibility
Sputter any conductive metal or alloy:
Aluminum (brilliant silver finish)
Copper (decorative & antimicrobial)
Chromium (hard, scratch-resistant)
Stainless steel (food-contact approved)
Titanium (biocompatible, wear-resistant)
Custom alloys available upon request.
Food-Grade Compliance
The coating process is entirely chemical-free and operates in a high-vacuum environment. No toxic residues, no leaching – meets FDA, EU 10/2011, and GB 4806 standards for direct food contact. Perfect for disposable spoons, forks, knives, plates, bowls, and lunch boxes.
Low-Temperature Process
Process temperature below 80°C (176°F) ensures zero deformation, discoloration, or degradation of plastic substrates – even for thin-walled items.
Eco-Friendly & Clean
Zero wastewater, zero VOC emissions, and no hazardous chemical baths. The closed-loop sputtering process consumes only electricity and argon gas. Target materials are fully utilized with minimal waste.
