5. forged steel ball Test
① Factory test
Casting balls test is an very important step. Real-time detection
will be carried out in the production process. Balls produced in
each shift will be sampled in large quantities and tested for size,
hardness, chemical composition, drop test, core pulling and impact
value to ensure the quality of steel balls.
② The third party test
According to the customer different demand, casting balls can be
tested by any third party.
6. forged steel ball Packing
Casting balls are usually packed in container bags and steel drums,
