- Pretreatment & E-Coating System
When your paint shop demands precision, consistency, and environmental compliance, a reliable Pretreatment and Electrophoretic Coating (E-Coating) System makes all the difference.
Tiancheng Coating, with over 30 years of expertise since its founding in 1995, designs, manufactures, and installs advanced pretreatment and E-coating systems tailored to the unique needs of manufacturers around the world. Our solutions have earned the trust of leading automotive OEMs, ensuring that every system we deliver meets strict regional standards. All our equipment complies with European CE regulations, while our electrical systems fully meet US UL certifications.
Drawing on deep knowledge of industrial pretreatment technologies, Tiancheng Coating offers flexible conveyor solutions to integrate seamlessly with your production flow. Depending on your processes and space constraints, you can choose from three proven conveyor options: pendulum conveyor system, electric monorail system (EMS) and programmable hoist conveyor system.
The pendulum conveyor system is renowned for its stable and reliable operation, easy maintenance, and excellent throughput. It’s particularly well-suited for handling workpieces with complex structures or those requiring specific hanging angles. This system remains a classic choice for transporting large, heavy, or irregularly shaped components with efficiency and precision.
The electric monorail system (EMS) stands out for its exceptional flexibility, precise positioning capabilities, and space-saving design. It’s particularly ideal for modern production lines that demand a high level of automation, complex process routes, limited space, or the need for meticulous control over workstation cycle times.
The programmable hoist conveyor system is designed with powerful lifting capacity and extensive operational coverage, making it especially suitable for handling construction machinery structures and large cast or forged parts. It’s a smart solution for saving space and reducing costs while maintaining high production efficiency and reliable performance.

Our team is ready to help you achieve outstanding coating results with maximum efficiency and significant cost savings. We’d love to connect and explore how we can support your goals.
Our solutions cover every critical part of an automotive coating line, including Pretreatment and E-Coating Systems, Spray Booths, Oven&Coolers, ASU&ARU, and dedicated Working Decks.
A pretreatment and E-coating system is a critical combination of equipment used in coating processes, especially before electrophoretic painting. It handles essential surface treatments like cleaning, degreasing, and phosphating on workpieces such as automotive bodies and metal parts. These steps create a uniform, high-quality base layer for subsequent electrophoretic coating (E-coat). Automated processes ensure high efficiency, consistent results, and environmental compliance, making this system widely used in automotive manufacturing, metal fabrication, and similar industries.
Our E-coating rectifiers fully comply with the highest safety standards outlined in UL and CE regulations. We integrate interfaces that support IoT and Industry 4.0 connectivity, enabling maximum productivity at minimal cost. These features come as standard, not optional extras. Additionally, all our rectifiers are enclosed in robust industrial cabinets, providing extra protection and safety for your operations.

The CED (cathodic electrodeposition) coating process is a method for applying protective and decorative coatings to various parts and components. It uses an electric current to deposit paint or coating materials onto conductive surfaces, resulting in a uniform, durable layer with excellent corrosion resistance.
In the automotive industry, CED coatings are widely used to protect and enhance the appearance of vehicle parts such as car bodies, chassis, suspension components, and other metal parts. CED coatings provide uniform thickness and strong adhesion, helping prevent rust, weathering, and other environmental damage. This ensures long-lasting durability and extends the service life of automotive components.
Enhance your automotive coating line applications with solutions designed for outstanding vehicle finishes and optimal paint shop performance. Rely on Tiancheng Coating for innovative systems that deliver superior quality, efficiency, and proven results.
