In recent years, with the continuous advancement of automation and intelligent manufacturing, metal surface treatment technology has been increasingly applied in industries such as automobiles, motorcycles, home appliances, and hardware. As a leading manufacturer of coating production line equipment in China, Jiangsu Suli Machinery Co., Ltd. is committed to providing customers with efficient, eco-friendly, and energy-saving surface treatment solutions. Based on years of technical expertise, the company continuously optimizes its electrophoretic coating lines, promoting a comprehensive upgrade of metal surface protection and decorative processes.
Electrophoresis: A Key Process in Metal Surface Treatment
Electrophoresis (Electrophoretic Coating) is an advanced metal surface treatment process that uses an electric field to deposit charged particles from a water-based coating onto a metal surface, forming a dense protective film. This process significantly improves the corrosion resistance and adhesion strength of the coating, ensuring uniform film thickness and smooth appearance. Compared to traditional spray coating, electrophoretic coating produces almost no harmful gases, making it more compliant with today’s industrial sustainability and green manufacturing standards.
The cathodic electrophoretic coating lines developed by Jiangsu Suli Machinery Co., Ltd. use automated control systems to precisely regulate current and voltage, ensuring consistent coating thickness. After pre-treatment, the workpiece is immersed in an electrophoresis tank; under an electric current, positively charged paint particles are attracted to the negatively charged metal surface, forming a uniform film layer. The entire process can be fully automated, enabling continuous production, improving efficiency, and reducing labor costs.
Wide Applications: From Automobiles to Home Appliances and Hardware
Electrophoretic coatingwas first used for automotive primer production lines, and has since expanded to motorcycles, home appliances, construction hardware, air conditioner housings, eyewear, locks, and other industries. Jiangsu Suli Machinery Co., Ltd. customizes electrophoretic coating equipment of various specifications based on customer needs, compatible with multiple coating materials such as epoxy resin, electrophoretic paint, and water-based coatings. The equipment is designed to meet different requirements for workpiece size, production capacity, and process standards.
Suli’s coating lines lead the industry in corrosion resistance, energy efficiency, and environmental performance. Each system is equipped with automatic monitoring and control of key parameters, including bath temperature, pH, and conductivity, ensuring stable and reliable operation. Supporting systems such as drying ovens, circulation and filtration units, and automatic loading robots enable the entire line to achieve high efficiency, precision, and product quality.
Innovation-Driven: Promoting Green and Intelligent Manufacturing
As a professional coating production line manufacturer, Jiangsu Suli Machinery Co., Ltd. continues to take technological innovation as its core strength. The company integrates advanced design concepts and energy-saving technologies, constantly innovating in electrophoresis systems, paint lines, pre-treatment processes, and plant-wide automation control. By optimizing airflow circulation, heat recovery, and smart monitoring modules, Suli’s electrophoretic coating systems achieve international-level performance in energy efficiency, environmental protection, and maintenance convenience.
Looking ahead, Jiangsu Suli Machinery Co., Ltd. will continue to strengthen its research and development in electrophoretic and spray coating technologies, further improving automated electrophoretic coating solutions to help customers achieve high-quality, high-efficiency, and green production. The company will maintain an open and cooperative approach, partnering with domestic and international automotive, motorcycle, and appliance manufacturers to advance China’s intelligent coating industry to a higher level.
