Hollow Steel Sphere Production
Mould Pressing ,water pressure
1. stamping press is shape steel sheet by deforming it with a mould.
2. Welded two steel hemispheres together and grinding the welding seams .
3. Mirror polishing the hollow steel balls.
Invisible Welding Seams
Spin two steel hemispheres, then welding together, finally grinding the welding seams and mirror polishing it .
This is the thickest steel ball choice.
