The frames, rims and front forks of two-wheelers such as electric bikes, motorcycles and bicycles are metal parts with large batch sizes and regular shapes, very suitable for conveyorized powder coating. Taizhou Yufeng Intelligent Equipment Co., Ltd. designs a continuous conveying powder line for two-wheeler manufacturers, achieving high-volume, high-quality powder coating.

Continuous conveying line

The conveyorized powder line uses an overhead chain or floor conveyor, and workpieces pass continuously through the pretreatment, powder coating and curing stations at a fixed cycle. The conveying speed matches the process time of each step to ensure full treatment. Racks on the chain are designed according to workpiece shape for stable hanging. Continuous conveying reduces loading and unloading waiting, suiting high-volume production.

Automatic powder application system

The powder coating station is equipped with automatic guns, and the spraying path is planned according to workpiece shape. The number and multi-angle arrangement of automatic guns ensure uniform coverage. The powder recovery system recovers overspray powder to improve utilization. The booth airflow design prevents powder escape, and the color change flow is standardized.

Curing and cooling

The curing oven sets temperature and time according to the powder type. Two-wheeler parts commonly use powder with a higher curing temperature. After curing, workpieces pass through a cooling section before unloading to avoid heat damage and burns. The oven uses energy-saving design with high thermal efficiency. The temperature curve is recorded to guarantee curing quality.

Racks and capacity

Rack loading affects output per batch. The hanging design optimizes density while ensuring coating quality. Racks are cleaned regularly to remove powder accumulation. The powder line cycle and curing oven capacity match, and the whole line capacity is designed according to customer output. The line reserves extension positions for capacity growth.

Quality testing

Two-wheeler part coatings undergo film thickness, adhesion, impact, bending and salt spray tests. Frames focus on stone chip resistance and weathering performance. Test data is bound to the product number to form a factory file. Non-conforming products are reworked, and qualified products enter assembly or packing.
