Electroplating with Passivation and In-line HDE Line
Automated Electroplating Plants with In-line Passivation and Hydrogen De-embrittlement
At Suntech Industrial Solutions, we engineer high-performance electroplating systems tailored to industries where corrosion resistance, coating consistency, and metallurgical integrity are paramount. Our lines are optimized for coating systems such as Alkaline Zinc, Zinc-Nickel, and Zinc-chrome, with post-treatment options including passivation, sealing, and hydrogen de-embrittlement—all inline, under precise control.
Each system is designed as a turnkey delivery—from pretreatment and plating to baking ovens and automation—backed by our robust process integration expertise.
Process Flow
Our process sequence, optimized for performance, reliability, and uniform surface finish:
Each step is carefully monitored through our automated control systems, with recipe-based program management ensuring repeatability and traceability.
Purpose and Benefits
Electroplating provides a sacrificial or protective metallic layer that enhances corrosion resistance, improves wear characteristics, and refines surface appearance. Zinc and zinc-alloy coatings (like Zinc-Nickel) are commonly used in automotive and aerospace applications for their ability to withstand harsh conditions. The integrated hydrogen de-embrittlement oven reduces the risk of delayed cracking in high-strength steel parts by removing absorbed hydrogen, thereby ensuring long-term structural integrity.
Industries & Products
Common applications include fasteners, brackets, chassis parts, and structural hardware for automotive, aerospace, defense, and construction industries. Zinc-Nickel is widely used in EV components and fuel systems for its superior corrosion performance.
Configuration & Capabilities
Systems feature modular plating bays, in-line baking ovens, and advanced crane automation.
Notable features:
- Fully automated crane systems with PLC/SCADA control
- Configurable for barrel, rack, or jig-based components
- In-line hydrogen de-embrittlement ovens (160–220°C, up to 6 hours cycle)
- Alkaline and acid-compatible plating tanks with filtration
- Integrated passivation and sealing systems
- Maximum capacity delivered: __ tons/day (placeholder)
