Based in Huzhou, Zhejiang, China, Deqing Leixin Coating Equipment Co., Ltd. has been a trusted manufacturer of surface finishing solutions since 2011. With a factory spanning 1,000–3,000 square meters and a dedicated team of 51–100 employees, we specialize in designing and building turnkey vehicle parts electrophoresis lines that integrate full pretreatment and electrocoating processes. Our equipment is exported to over 15 countries and regions, including North America, South America, Europe, and Southeast Asia, backed by ISO9001 quality management system certification. This product line is engineered to deliver consistent, high-quality coating results for automotive components, ensuring excellent corrosion resistance, uniform film thickness, and long-term durability.
What is a Turnkey Vehicle Parts Electrophoresis Line?
This is a complete production system that automates the entire surface treatment process for vehicle parts: from cleaning and phosphating (pretreatment) to electrocoating (cathodic or anodic) and curing. The term “turnkey” means we provide everything – design, manufacturing, installation, and commissioning – so you can start production immediately. The line is fully customizable to match your part dimensions, production volume, and coating specifications.
Key Features & Technical Specifications
- Full Pretreatment Stages: Includes degreasing, water rinsing, surface conditioning, phosphating, and passivation – all in a compact, conveyorized layout. This ensures superior adhesion and corrosion protection before electrocoating.
- Advanced Electrocoating Tank: Equipped with rectifier, ultrafiltration system, and anolyte circulation to maintain paint bath stability and achieve uniform film thickness (typically 15–30 μm).
- PLC & HMI Control: Automated control of conveyor speed, temperature, voltage, and dwell time. Real-time monitoring and data logging for quality traceability.
- Energy-Efficient Curing Oven: Uses gas or electric heating with precise temperature control (up to 200°C). Insulated panels minimize heat loss.
- Modular Design: Easy to expand or reconfigure for future production changes.
- Low Maintenance: All components are selected for long service life, with easy access to pumps, filters, and valves.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between cathodic and anodic electrocoating?
A: Cathodic electrocoating (CED) is the most common for automotive parts because the part is negatively charged, attracting positively charged paint particles, resulting in superior corrosion resistance. Anodic is less common and used for non-critical parts. Our line is designed for cathodic electrocoating by default, but can be configured for anodic if needed. -
Q: Can this line handle large parts like truck frames?
A: Yes, the tank dimensions and conveyor system are fully customizable. We have built lines for parts up to 4 meters long. Please provide your part drawings for a tailored solution. -
Q: What is the typical film thickness achieved?
A: With proper process control, we achieve 18–25 μm uniform film thickness. The rectifier settings and voltage can be adjusted to reach 15–30 μm. -
Q: How long does installation and commissioning take?
A: Typically 4–6 weeks from arrival at your site, depending on complexity. Our team provides on-site supervision and training for your operators. -
Q: What kind of after-sales support do you offer?
A: We provide a 12-month warranty on all equipment, remote technical support, and spare parts availability. We also offer annual maintenance contracts and process optimization services. -
Q: Is the line compliant with environmental regulations?
A: Yes, our design includes a closed-loop rinse water system, exhaust scrubbers, and low-VOC paint options. We can help you meet local emission standards. -
Q: Can I see a reference installation?
A: Absolutely. We can arrange a visit to a working line in China or provide video tours of similar installations. Many of our clients in Europe and the Americas have publicly shared their experience. -
Q: What is the minimum order quantity?
A: We accept orders for a single turnkey line. However, we also offer smaller pretreatment systems for pilot runs. Contact us for details.
