Cathodic Electrophoretic Coating Line for Motorcycle Frames

Automated surface pre-treatment and cathodic electrophoretic primer coating system designed specifically for motorcycle frames and similar metal workpieces.

Automated surface pre-treatment (degreasing, rust removal, surface conditioning, silane/zirconium treatment/phosphating) and cathodic electrophoretic primer coating for metal workpieces, particularly motorcycle frames. Achieves efficient cleaning and dense, anti-corrosive pre-coating film through fully automatic immersion and spray methods.

PLC or industrial computer controls parameters including rectifier voltage, bath temperature, immersion/spray time, and ultrafiltration/recovery. Motorcycle frames are processed through multiple stages according to preset programs for complete surface treatment.

• Automation: Entire process requires no manual intervention, supporting high-volume continuous or indexed fully automatic production
• High Precision: Programmable parameter control ensures treatment consistency on complex internal tube surfaces, crevices, and dead corners
• Energy-Efficient & Environmentally Friendly: Circulation filtration and closed-loop ultrafiltration recovery reduce wastewater discharge and paint waste
• Application Fields: Motorcycle manufacturing, e-bike frame hardware, automotive components, ATVs, and two-wheeler parts industries

• Nozzles: Venturi mixing nozzles and pre-treatment universal quick-detachable flushing nozzles for full coverage
• Spray Piping: Corrosion-resistant PVC/stainless steel pipelines with precision pressure sensors and flow control
• High-Pressure Pumps: High-efficiency corrosion-resistant centrifugal pumps with digital adjustable rectifier power supplies

• Conveyor Chain: Acid/alkali-resistant, heavy-load-capable overhead suspension conveyor with frequency-controlled variable speed (0.5-5 m/min)

• Main Processing Tanks: Heavy-gauge stainless steel or carbon steel with corrosion protection lining
• Reservoir Tanks: Double-layer insulated tanks with high-precision level transmitters and automatic replenishment

• Multi-Stage Filters: Bag filters (≤25μm) and dedicated ultrafiltration membrane modules
• Circulation Pumps: Heavy-duty corrosion-resistant vertical pumps for continuous circulation

• Heating Methods: Steam heat exchangers with PID temperature control accuracy of ±1°C
• Temperature Control: PT100 industrial temperature sensors with intelligent multi-channel controllers

• Main Control Unit: PLC (Siemens S7-1200/1500 series) with touchscreen HMI
• Sensors: Flow meters, online pH meters, conductivity meters, and bath content monitors
• Data Management: Recipe storage, intelligent fault diagnostics, and production management reporting

• Exhaust System: Low-noise centrifugal fans with acid mist/organic exhaust gas treatment
• Safety Protection: Emergency stop buttons, insulated walkways, protective fencing, and safety light curtains
