Deqing Leixin Coating Equipment Co., Ltd., established in 2011 and ISO9001 certified, is proud to offer our Vehicle Parts Cathodic Electrophoresis System – a solution engineered for outstanding anti-corrosion performance. With over a decade of manufacturing expertise and a dedicated team of 51–100 employees, we design and produce CED (Cathodic Electrodeposition) systems that deliver uniform, durable coatings on complex automotive components. Our system is trusted by clients across North America, Europe, Southeast Asia, and beyond, with annual export values reaching US$1–1.5 million. This equipment is ideal for OEMs and tier suppliers seeking to enhance the corrosion resistance of their vehicle parts while maintaining production efficiency.
The Vehicle Parts Cathodic Electrophoresis System is built on proven technology that deposits a protective paint film onto metal surfaces through an electrochemical process. The result is a seamless, high-adhesion coating that penetrates recesses, edges, and internal cavities – areas often missed by traditional spraying. Our system incorporates advanced PLC control, energy-efficient rectifiers, and a modular tank design, ensuring consistent bath chemistry and minimal downtime. Whether you need to coat chassis parts, brackets, fasteners, or interior components, this system offers a reliable solution for long-term corrosion protection.
Key Features & Technical Specifications
- Outstanding Anti-Corrosion Performance: Achieves salt spray resistance up to 500+ hours (depending on paint formulation) – ideal for automotive harsh environments.
- Uniform Coating Thickness: Electrophoresis ensures even coverage from 15–30 microns, with no drips, runs, or thin spots.
- High Transfer Efficiency: Over 95% paint utilization reduces material waste and VOC emissions – environmentally friendly and cost-effective.
- PLC & HMI Control: Automates process parameters (voltage, current, temperature, dwell time) for repeatable batch quality.
- Modular Design: Includes pre-treatment tanks, electrodeposition tank, post-rinse stages, and curing oven – can be expanded as production grows.
- Durable Tank Construction: Stainless steel or carbon steel lined with acid-resistant materials, ensuring long service life.
- Energy-Efficient Rectifier: IGBT-based power supply with low ripple for stable deposition and reduced power consumption.
- Optional Features: Anode/cathode panel customization, automatic conveyor system, and remote monitoring via IoT.

Frequently Asked Questions (FAQ)
1. What types of vehicle parts can be coated with this system?
Our system is designed for a wide range of metal components, including chassis parts, brackets, fasteners, suspension arms, engine mounts, brake calipers, and interior brackets. Parts made of steel, iron, and some aluminum alloys (with proper pre-treatment) are suitable.
2. How long does the coating last in salt spray tests?
With standard cathodic epoxy paint, we achieve over 500 hours of salt spray resistance per ASTM B117. For more demanding applications, high-performance paints can extend to 1,000 hours. Test results depend on pre-treatment quality and paint formulation.
3. Is the system easy to operate for non-experts?
Yes. The PLC-controlled HMI provides step-by-step prompts and automatic process control. Operators only need to load/unload parts and monitor the screen. We provide training and a user manual for your team.
4. What is the typical power consumption of the system?
For a standard line (e.g., LX-CED-500), total installed power is approximately 80–120 kW, but actual consumption depends on production volume. The IGBT rectifier offers high efficiency, reducing energy costs compared to older SCR systems.
5. Can the system be customized for different part sizes?
Absolutely. We design tank dimensions, conveyor speed, and even the number of anodes to match your specific part geometry. Our engineering team will conduct a feasibility study before finalizing the design.
6. Do you provide installation and commissioning support?
Yes. We offer on-site installation supervision and commissioning services. Our technicians can travel to your facility to ensure the system runs smoothly. Remote support is also available via video call.
7. What is the warranty period for the equipment?
We provide a standard 12-month warranty covering defects in materials and workmanship. Extended warranty options are available upon request. Spare parts are stocked for fast delivery.
8. How does this system compare to powder coating for anti-corrosion?
Cathodic electrophoresis offers superior edge coverage and internal cavity protection compared to powder coating. It is also more cost-effective for high-volume, complex-shaped parts. However, the choice depends on your specific application; we can advise you based on your requirements.
