The painting assembly line equipment is suitable for spray painting and plastic treatment on the surface of workpieces, and is mostly used for painting operations on single or small batches of workpieces. It is combined with transportation machinery such as hanging conveyors, electric rail carts, and ground conveyors to form transportation operations. The spray type multi station pre-treatment unit is a commonly used equipment for surface treatment, which uses mechanical flushing to accelerate chemical reactions to complete processes such as oil removal, phosphating, and water washing. The typical process of spray pre-treatment for steel parts is: pre degreasing, degreasing, water washing, water washing, surface conditioning, phosphating, water washing, water washing, and pure water washing. Pre treatment can also use shot blasting cleaning machines, which are suitable for steel parts with simple structures, severe corrosion, and no or little oil. And there is no water pollution.
