Automated Spraying Production Line for Construction Machinery

Qingdao Ruichi Fenghui Electromechanical Equipment Co., Ltd. specializes in providing painting production line solutions for various manufacturing industries. With profound technical expertise and a relentless pursuit of quality, the company has established an excellent reputation in the coating field.

The company's painting production line operates through the coordinated functioning of multiple core components, with each segment working in close collaboration to ensure efficient and precise coating operations. The pre-treatment equipment serves as the critical starting point of the entire process, employing professional degreasing and derusting techniques to achieve a clean surface on workpieces, laying a solid foundation for subsequent procedures. The powder coating system and spray painting equipment can flexibly switch operation modes based on the material and appearance requirements of different products, enabling precise application of coatings and ensuring uniformity and adhesion of the coating layer. The powder recovery unit skillfully collects and reuses unattached powder, reducing production costs while adhering to green and environmentally friendly principles. The heating, drying, and curing oven, supported by a stable heat source system, accurately controls temperature to facilitate rapid and perfect curing of the coating. The electrical control system acts as the intelligent core of the production line, providing smart and precise regulation of each segment to ensure stability and efficiency throughout the production process. The overhead conveyor chain operates smoothly and at a constant speed, transporting workpieces orderly to various stations, ensuring seamless connectivity in the production flow.

The application scope of this painting production line is extremely broad, covering surface treatment for metal products such as automotive parts, household appliances, medical devices, hardware products, construction machinery, electromechanical products, and motorcycles, significantly enhancing product corrosion resistance and aesthetics while extending product lifespan. Additionally, for wooden furniture, plastic products, and others, professional coating can impart unique appearance and protective properties, meeting diverse market demands.

The workflow is rigorous and standardized. It begins with comprehensive and meticulous pre-treatment of workpieces, sequentially completing processes such as degreasing, derusting, phosphating, and passivating to form a uniform, rough gray phosphating film on the workpiece surface. This film not only provides excellent rust prevention but also greatly enhances the adhesion of the spray coating. Subsequently, the workpiece enters a preheating stage to raise its surface temperature for better primer adsorption. This is followed by primer spraying to initially build a protective barrier. After baking to firmly adhere the primer, surface painting is conducted to shape the final appearance and color of the product. Finally, high-temperature curing ensures tight integration of the coating with the workpiece, completing high-quality coating operations and endowing products with exceptional quality and visual appeal.
