Barrel Zinc Phosphate : Surface modification and finishing of ferrous and nonferrous metals is widely carried out using a metal pretreatment technique known as phosphating. The parts are filled in barrels and process through various stages of operations to achieve desired phosphate coating over parts.
Phosphating is favored for reasons of providing good corrosion resistance, wear resistance, adhesion and lubrication properties, high speed of operation and low cost.
The process of phosphating is widely used in automobile, process and appliance industries.
