Dip Pretreatment Plant is also known as 7 tanks or 11 tanks process plant.
In this components are loaded in basket and the basket is dipped in various chemical tanks as per chemical process. For basket handling from one tank to another tank we can use hoist (manual) or automated transporter system. After pretreatment process is done same basket can be inserted inside inline water drying oven or we can unload components from basket and load them on conveyor, which will go inside of Conveyorised water drying oven for drying off the water from components before powder sprayed on components.
For loading and unloading of articles into various tanks in pretreatment process transporter system is mainly used with a programmed cycle. The cycle is based on the time required in particular tank as specified and also sequenced in such way that critical tanks (degrease, derust, Zn phosphate and WDO) are treated on priority, so articles are have been removed from this tanks with minimal time loss.
1. Precise Control with the help of PLC programming.

Water drying oven is used for drying of article after pretreatment process. After this some moisture is on the object which has to be dry out because before powder coating, component should be clean and free from moisture. Followings are the types of oven-
This type of oven is in line with the dip pretreatment process. This oven is also known as tank type oven. This oven has sliding doors which are pneumatically/hydraulically operated. The heater box for this oven is at the side of oven. The transporter/hoist is used for loading and unloading the basket in the oven from top side. It has pneumatic/hydraulic opening doors.
In this oven articles are loaded on the trolley and then trolley is pushed inside the oven after batch schedule time trolley is taken outside the oven. In this oven trolley arrangement and door are provided. In this oven manual push pull track are also provided for loading and unloading of components.
In this oven pretreatment articles are hung on the conveyor and then conveyor carries the article through oven. Articles travel for particular time to get water dried and conveyor brings the article outside. In this oven article entry and exit cut out is provided perpendicular to the ground.
