Qingdao Ruichifenhui Mechanical and Electrical Equipment Co., Ltd. has been deeply engaged in the spraying field for many years. With advanced technology and excellent craftsmanship, the company has achieved remarkable accomplishments in the manufacturing of coating production lines.

The company's coating production line is considered an industry benchmark, featuring a precise and comprehensive structure. The pre-treatment equipment, responsible for cleaning the surface of workpieces, serves as the foundation for high-quality coating. The powder spraying system and painting equipment ensure precise application according to different materials and appearance requirements, guaranteeing uniform coating and vibrant colors. The powder recovery equipment efficiently collects unattached powder, enabling high resource utilization. The heating, drying, and curing oven provides the critical temperature environment for the final formation of the coating. The heat source system continuously supplies heat to the oven, while the electrical control system acts as an intelligent brain, precisely regulating each segment of the production line. The overhead conveyor chain seamlessly connects the entire process with stable and efficient transportation.

The application scope of the coating production line is extremely broad. In the metal products sector, ranging from automotive parts to hardware products, construction machinery to electromechanical products, and motorcycles, coating effectively enhances corrosion resistance and aesthetics while extending product lifespan. In non-traditional metal fields, wooden furniture gains renewed appeal after coating, and plastic products achieve superior appearance and protective performance.

The workflow is rigorous and orderly. At the beginning of the operation, workpieces undergo pre-treatment processes such as degreasing, derusting, phosphating, and passivation. The cleaned workpiece surface forms a gray phosphating film, which not only provides significant rust prevention but also greatly enhances the adhesion of the spray coating. Subsequently, the workpiece enters the preheating stage, followed by the application of a primer to establish initial protection. After baking, surface painting is performed to賦予 the workpiece its final color and texture. Finally, high-temperature curing ensures the coating firmly adheres, completing the entire high-quality coating process and providing various products with a durable and aesthetically pleasing "outer layer."
