Strict quality control is maintained at every step of the production process, right from the receipt of raw material till the steel balls roll out of the factory passing through several checks and re-checks. Selection of raw materials is very important. Every coil of wire or a piece of bar is chemically analyzed and tested for its physical properties before it is approved for further process. It is ensured that forgings are uniform in diameter and acid etched. After heat-treatment, the whole lot is checked for hardness and micro-structure. After lapping, every machine lot is checked for surface defects, roughness and perfect roundness using precision instruments. Each ball is visually inspected by specially trained personnel & then passed through sensor sorting machines for 100% dimensional accuracy. The balls are then finally packed, after giving them anti-corrosive coating to make them rust-proof.
