The component painting workshop of this business unit has two production lines, the frame line and the comprehensive line. It can complete the degreasing and degreasing of chassis frames, floor frames and other large-area structures in an assembly line manner. Pre-treatment processes such as pickling, phosphating, and priming. The workpiece can continuously complete a series of processing processes such as primer baking, topcoat spraying, and topcoat baking on the conveyor chain. The workpieces after the top coat is baked can be used directly. The entire production line has an annual designed production capacity of 3,000 pieces (single shift).
The comprehensive line has an integral closed comprehensive spray treatment line for degreasing, pickling and phosphating, and two suspended conveyor chains. The workpieces enter the 10 relatively independent spray chambers of the overall spray processing line in sequence on the conveyor chain. Through a large number of nozzles, all-round and multi-angle spraying is achieved to achieve good processing effects. The comprehensive line also has a steam drying room, a water-rotating bottom and topcoat spraying room, and a bottom and topcoat drying room. The workpiece can undergo a series of process steps such as pre-treatment, primer spraying, and topcoat spraying at one time on the conveyor chain. The product can be put online immediately after being offline, and the production efficiency is extremely high. The production line's annual design production capacity is 1.34 million pieces (single shift). The products it processes range from various connectors, sealing plates, strips, flat panels, box assemblies, small steel frame beam assemblies, various small frame assemblies, to as large as iron front and rear panels of passenger cars.
The company is also equipped with a specialized physical and chemical laboratory, most of which use imported testing equipment, which can test the raw materials for painting as well as the degreasing tank, pickling tank and phosphating tank at the production site at any time. The bath liquid is tracked and tested to ensure that the key parameters meet the process requirements and ensure the coating quality.
