Phosphating Line
Phosphating Systems for Surface Conditioning and Paint Bonding
Suntech’s phosphating lines support industrial-grade surface pretreatment for parts requiring enhanced paint adhesion, wear resistance, and corrosion inhibition. We build systems for both zinc and manganese phosphate processes, along with tailored activation and oiling stages.
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
Phosphating improves paint bonding, reduces friction, and adds wear resistance. Zinc phosphate is ideal for corrosion prevention under paint, while manganese phosphate is used for parts under high load/stress due to its lubricity. The process enhances mechanical properties while also preparing surfaces for further treatments.
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
Plants feature heated tanks with agitation, spray or immersion configurations, and Sludge separators and oil skimmers. Available with drying ovens.
Notable features:
- Fully automated crane systems with PLC/SCADA control
- Optional ultrasonic cleaning and pickling
- Integrated passivation and post-phosphating oiling stations
- Robust material handling and dosing systems
- Maximum capacity delivered: __ tons/day (placeholder)
