Wind turbine equipment shell spraying production line

Qingdao Ruichifenhui Mechanical and Electrical Equipment Co., Ltd. has become a trusted partner for many enterprises in the industry, thanks to its advanced coating production line technology. The company's coating production line integrates innovative design and exquisite craftsmanship, providing efficient and high-quality solutions for the surface treatment of various products.

The coating production line operates through the coordinated functioning of several core components. The pre-treatment equipment serves as the starting point, utilizing industrial processes to perform tasks such as degreasing and derusting on workpieces, laying a solid foundation for subsequent procedures. The powder coating system and painting equipment can flexibly switch operation modes according to different product requirements, precisely controlling the amount and coverage of the coating to ensure an even and durable finish. The powder recovery equipment ingeniously recycles unused powder for reuse, effectively reducing production costs and adhering to environmental principles. The heating, drying, and curing oven tunnel, with precise temperature control, allows the coating to cure under optimal conditions. The heat source system provides a stable thermal supply to the oven, ensuring a constant internal temperature. The electrical control system acts as the "intelligent brain" of the entire production line, accurately managing the operational rhythm and parameters of each segment. The overhead conveyor chain systematically transports workpieces, enabling seamless integration of the production process.

This coating production line has a wide range of applications, covering surface treatment for metal products such as automotive parts, household appliances, medical devices, hardware products, construction machinery, electromechanical products, and motorcycles, significantly enhancing the corrosion resistance and aesthetics of the products. Additionally, it can impart unique appearances and protective properties to wooden furniture and plastic products through coating.

In terms of workflow, the process begins with comprehensive pre-treatment of the workpiece, including degreasing, derusting, phosphating, and passivation, resulting in a uniform, rough gray phosphating film on the surface that prevents rust and enhances the adhesion of the spray coating. Next, the workpiece enters a preheating stage, followed by the application of a primer to initially form a protective layer. After baking, surface painting is carried out to shape the final appearance of the product. Finally, through high-temperature curing, the coating bonds tightly with the workpiece, completing a high-quality coating operation that enhances both the product's quality and visual appeal.
