Mining Machinery Spraying Line Production Line

Qingdao Ruichi Fenghui Electromechanical 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 combines innovative design and exquisite craftsmanship, providing efficient and high-quality solutions for the surface treatment of various products.

Its coating production line operates through the coordinated functioning of multiple core components. The pre-treatment equipment serves as the starting point, utilizing specialized processes to perform degreasing, derusting, and other pre-treatments on workpieces, laying a solid foundation for subsequent procedures. The powder spraying system and painting equipment can flexibly switch operation modes according to different product requirements, precisely controlling the amount and coverage of coating application to ensure an even and durable coat. The powder recovery equipment cleverly collects and reuses unattached powder, effectively reducing production costs and adhering to environmental protection principles. The heating, drying, and curing oven tunnel, through precise temperature control, allows the coating to cure and form under optimal conditions. The heat source system provides a stable thermal supply to the oven, ensuring constant internal temperatures. The electronic control system acts as the "intelligent brain" of the entire production line, accurately managing the operational rhythm and parameters of each stage. The overhead conveyor chain systematically transports workpieces, ensuring seamless continuity in the production process.

This coating production line has a wide range of applications, covering the surface treatment of 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 also provide wooden furniture and plastic products with unique appearances and protective properties 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 build 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 process that enhances both the product's quality and visual appeal.
