The pre-treatment is divided into three forms: spray type, immersion type and submersible type. The treatment method is selected according to the workpiece and specific production requirements.

The spray treatment method uses the spray principle to make the liquid medicine continuously act on the surface of the workpiece. It has strong working continuity and high efficiency. It is suitable for the requirements of large quantities of operations. The treatment effect is good. It is suitable for large pipe fittings, long pieces and items with simple structure. In general, it uses a high frame structure to save ground space.


2. Diving

The submersible treatment method is to immerse the workpieces into the swimming pool by means of hanging empty chains for treatment in the liquid medicine pool. It is suitable for the treatment of objects with complex shapes, and has good effect and saves the amount of liquid medicine
