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.
