6.How a ball is made?
Wire coil:
Steel wire of specific material and size were inspected for correctness.
Cutting:
The wire is cut into required length.
Forging/heading:
Spherical shapes between dies are formed.
Deflashing:
The flash line along the circumference is removed.
Heat treatment:
Carbon steel and chrome steel balls are through hardened.
Cleaning/descaling:
Basic surface cleaning is done.
Hard grinding / filing:
An exacting process to achieve required sphericity and size of the steel ball.
Lapping:
The final surface finish is acquired through this process.
Polishing / bunishing:
Surface luster, working hardening, higher product life is achieved.
Passivation:
Carryover iron and other contaminants are removed and a surface film prevents atmospheric and water corrosion on stainless steel balls.
Inspection:
For surface finish,size and tolerance.
Rust preventive oil:
Applied on carbon and chrome steel balls to save from rusting and corrosion.
Package:
Poly bag and carton of bulk packaging.
Polybag and woven bag of bulk packaging.
Polybag and wooden case of bluk packaging.
