Motor housings and elevator parts use various materials including steel, cast iron and aluminum. Painting must balance anti-corrosion, appearance and batch efficiency. Taizhou Yufeng Intelligent Equipment Co., Ltd. designs painting and coating lines for electromechanical and elevator component companies, covering pretreatment, spraying, drying and inspection to help customers build standardized coating capability.
Spraying process for multi-material parts
Parts of different materials use differentiated pretreatment and spraying processes. Steel parts undergo degreasing and derusting, then primer and topcoat. Cast iron parts strengthen anti-corrosion treatment, and aluminum parts use conversion coating treatment. The compatibility between primer and topcoat is verified to avoid intercoat adhesion problems. Spraying parameters are set by material and color to ensure batch consistency.
Spray booth and color change management
The spraying station is equipped with a ventilated booth to control mist and solvent concentration. During color change, the gun and pipes are cleaned to prevent color mixing. The booth uses a modular structure for easy cleaning and maintenance. Waste gas is treated and discharged to standard, and environmental facilities are configured according to regulations. The gun is maintained regularly to ensure atomization.
Drying and curing process
After spraying, parts enter the drying oven for curing, with temperature and time set according to paint requirements. The tunnel uses zoned temperature control to adapt to different products. The oven is equipped with temperature control and recording systems, and the curing process is traceable. For high-volume production, the oven capacity matches the spraying cycle to avoid waiting.
Quality inspection and traceability
Coating quality is controlled through film thickness, adhesion, gloss and appearance inspection. Test data is bound to the product number to form a factory file. Motor housings focus on anti-corrosion and insulation mating surfaces, and elevator parts focus on appearance and abrasion resistance. Non-conforming products are reworked, and qualified products enter packing.
Line planning
When planning a motor and elevator parts coating line, provide the product material, size, output, colors and coating standard. We design the pretreatment, spraying, drying and inspection stations, and provide the equipment list and investment estimate.
