第一步：工件前处理，涂装质量的基础核心。正式喷漆前，需通过脱脂、水洗、除锈、除尘、烘干整套工序，彻底清除工件表面油污、氧化皮、铁锈、粉尘杂质。工件基材洁净干燥，才能保证油漆紧密附着，避免后期起皮、脱落、起泡，大幅提升涂层使用寿命。

Step 1: Pre treatment of the workpiece, the fundamental core of coating quality. Before formal painting, the entire process of degreasing, water washing, rust removal, dust removal, and drying must be carried out to thoroughly remove oil stains, oxide scales, rust, dust and impurities on the surface of the workpiece. The workpiece substrate must be clean and dry to ensure tight adhesion of the paint, avoid peeling, peeling, and foaming in the later stage, and greatly improve the service life of the coating.

第二步：工件上挂输送。将处理完成的工件整齐挂置在流水线挂钩上，调整输送链速度，根据工件尺寸、漆面要求匹配运行节拍，保证喷涂、烘干时间充足，适配不同工件涂装需求。

Step 2: Hang and transport the workpiece. Hang the processed workpieces neatly on the hooks of the assembly line, adjust the speed of the conveyor chain, match the running rhythm according to the size and paint requirements of the workpieces, ensure sufficient spraying and drying time, and adapt to different painting needs of workpieces.

第三步：无尘自动喷涂作业。工件进入封闭式无尘喷房，自动往复喷枪或喷涂机器人按照预设轨迹匀速喷涂，精准控制出漆量、雾化气压、喷涂距离，实现工件全方位覆盖，无死角、无漏喷，保证漆膜均匀细腻。复杂异形工件可搭配人工补喷，完善边角死角漆面。

Step 3: Dust free automatic spraying operation. The workpiece enters the enclosed dust-free spraying room, and the automatic reciprocating spray gun or spraying robot sprays at a constant speed according to the preset trajectory, accurately controlling the paint output, atomization pressure, and spraying distance, achieving all-round coverage of the workpiece, no dead corners, no missed spraying, and ensuring uniform and delicate paint film. Complex and irregular workpieces can be matched with manual spray painting to improve the paint surface of corners and dead corners.

第四步：流平挥发工序。喷涂完成后，工件进入流平区，静置挥发油漆内部稀释剂与有机溶剂，避免直接高温烘烤导致漆面起泡、针孔、橘皮，让漆面自然流平，提升平整度与光泽度。

Step 4: Leveling and volatilization process. After the spraying is completed, the workpiece enters the leveling area and is left to evaporate the internal thinner and organic solvent of the paint, avoiding direct high-temperature baking that may cause bubbles, pinholes, and orange peel on the paint surface. This allows the paint surface to naturally level, improving flatness and glossiness.

第五步：恒温烘干固化。流平完成的工件进入热风循环烘干炉，根据油漆材质设定标准温度与时间，恒温烘烤让油漆完全固化干燥，形成致密、耐磨、耐腐蚀的防护装饰涂层。

Step 5: Constant temperature drying and curing. The flattened workpiece enters the hot air circulation drying furnace, and the standard temperature and time are set according to the paint material. The constant temperature baking allows the paint to completely cure and dry, forming a dense, wear-resistant, and corrosion-resistant protective decorative coating.

第六步：冷却质检与入库。烘干后的工件自然冷却，工作人员检查漆面有无瑕疵，合格品打包入库，不良品统一返工整改，保障出厂成品品质。

Step 6: Cooling quality inspection and warehousing. After drying, the workpiece is naturally cooled, and the staff inspects the paint surface for defects. Qualified products are packaged and stored, and defective products are uniformly reworked and rectified to ensure the quality of the finished products before leaving the factory.
