Barrel Zinc Plating

Acadian Group's barrel zinc plating process provides cost-effective, high-volume finishing for small to medium-sized components. This efficient bulk processing method is ideal for fasteners, hardware, and small automotive parts requiring consistent trivalent zinc coating with excellent corrosion protection.

Our barrel plating systems offer optimal tumbling action to ensure uniform coating distribution on all surfaces while maintaining gentle handling of delicate components. The trivalent zinc process eliminates hexavalent chromium, providing environmentally responsible finishing that meets all current regulations.

This project demonstrates our capability to process large volumes of components efficiently while maintaining consistent quality standards. Our automated systems ensure precise control of coating thickness, chemistry, and processing parameters for optimal results.

This barrel zinc plating project involved processing thousands of small fasteners and hardware components using our advanced trivalent zinc plating system. The process began with thorough cleaning and surface preparation to ensure optimal adhesion and coating quality.

Components were loaded into specialized barrels designed for optimal tumbling action and current distribution. The trivalent zinc plating bath provided uniform coating deposition while the automated system monitored chemistry, temperature, and current density throughout the process.

Quality control included statistical sampling for coating thickness measurements, salt spray testing, and visual inspection. All components met ASTM B633 standards for zinc coating thickness and corrosion resistance performance.

The project showcased our baking facilities for hydrogen embrittlement relief on high-strength steel components, ensuring both corrosion protection and mechanical integrity. Environmental compliance was maintained throughout with proper waste treatment and recycling processes.
