Testing Equipments
We have a first-class laboratory and equipped with advanced testing equipment to ensure the quality:
Spectrometer:The wear resistance of forging steel balls are mainly determined by its chemical composition.
Hardness tester: Testing the surface hardness of steel balls.
Laser cutting machine-:Cuting the core of steel balls.
Impact tester: Ball mill with a diameter more than 6m, the larger the impact value, the lower the breaking rate.
Microscope: Observe the density and structure of steel balls.
Drop tester:Testing the service life of the steel balls.
