Spray Pre-Treatment Systems
Spray surface pretreatment lines are ideal for automated powder coating systems where the product quantity is high and where dipping type pretreatment does not meet the demand.
The work pieces moving on conveyor are cleaned and phosphated during passing through the active zones of the surface pretreatment line and then dried into an oven. Chemical process is selected as iron or zinc phoaphate or nano-technological process according to the raw material of work pieces. Each active zone have its own pump and nozzle section that works as closed circuit.
Our engineering department designs these systems according specific parameters as iron and zinc phosphate and nano technological processes.
Dip Pre-Treatment Lines
Dip pre-treatment systems are mostly preferred for manual and semi-automatic system use, where work piece quantities are low and not standard geometries. At the same time, this method provides an advantage for cleaning products such as tubes and profiles in order to degrease the interior surfaces.
The system consists of a suitable number of immersion tanks according to the chemical process, crane line and a basket where the parts to be cleaned are stored in the basket and dipping into the tanks. At the end of the process products are dried in drying oven.
In this method, mostly iron and zinc phosphate and aluminium chromate processes are applied. It is also suitable for nano technological processes.
