Advantages of Pretreatment Unit

Cleaning Performance

The design of the tank and the optimised delivery nozzles, provide for an extremely efficient method of removing oil, grease, and debris from the surfaces of workpieces, thus allowing for a better surface upon which to apply a coating.

Significant Savings in Labour and Material Costs

The automated operation of the pretreatment unit will significantly reduce the numbers of workers required on the production line to operate the unit.

Improved Quality and Service Life for Product

Utilising advanced degreasing and chemical passivation technologies, the pretreatment unit significantly reduces the possibility of secondary contamination from airborne particles during the coating process.
