Parts Painting Workshop under Stamping Workshop has one frame line and one comprehensive line for the pretreatment work of chassis frame, floor frame and some other large frames such as degrease, pickling, phosphating and primer dipping. The continuous processes can be completed on the conveying chain like: primer baking, final coating spraying and baking. After final baking, parts can be put to use directly. The overall productive capacity of two lines is 3000 pieces (single shift)...

There are one integrated closed spraying treatment line for degreasing, pickling and phosphating, 2 hanging conveying chains in comprehensive line. Work pieces on conveying chain go into 10 separate spraying chambers on integrated spraying treatment line in turn, after sprayed by a lot of nozzles from different angles and directions, they can get excellent treatment effect. In addition, comprehensive line has steam baking chamber，water rotation spraying chamber of primer and final coating and baking chamber of primer and final coating. A series of technique processes can be completed when the work pieces are on the conveying chain, including pre-treatment, primer spraying and top coat spraying etc. Parts can be immediately put into use, the production efficiency is very high. The designed productive capacity is 1.34 million pieces per year (single shift), ranging from various connecting parts，sealing plate，strip，flat plate，box assembly，small steel beam assembly and various frame assemblies to front and rear iron wall skin of bus.

In the physics and chemistry lab, most inspection devices were imported, with which painting material and degrease trough, pickling trough and phosphating trough can be inspected at any moment, assuring the key parameters and painting quality.
