Description
The oven is a convection oven that is used for curing of electrostatic powder coated workpieces usually at the temperature range between 180 and 200°C in 10 minutes.
This kind of ovens is a 2-doors box type. The system is a conveyorised one, i.e. batch oven with axial palette overhead conveyor that works in a step-by-step manner. These ovens are operated as follows:
1. Workpieces coated with powder are loaded manually to the conveyor at the loading station.
2. Then they are moved as one batch into the oven and the curing process starts.
3. Meanwhile, loading station is being emptied and loading operation continues.
4. The end of the process happens in cooling and unloading station at the exit side of the oven.
This type of ovens is a good fit mostly for step-by-step continuous powder coating systems combined with a powder coating booth at the same line. In this system workpiece sizes are big and weight is heavy.
Ovens are heated with electricity, liquid or gas fuel.
Our ovens can be produced in different size options in order to satisfy any customer’s requirements and desire. However, it is made for extra price but the given price does not include trolleys. Interval between hooks is 745 mm. Also, the given price does not include hanging apparats.
