In the Dip Pretreatment process, there is a sequential arrangement of the process tanks in accordance with the designed chemical process. The articles are hung onto a load bar or are put into a cage / basket and are moved from one tank to another using overhead hoist arrangement with manual controls or with the help of Transporters with manual or automatic controls. The article is expected to remain inside the respective tank for the specified time as per the designed chemical process. Another alternative material handling mechanism is the use of overhead chain conveyors, which are dipped in the tanks. This alternative is mainly used for large sized, low volume articles.
