Raw Materials | At its beginning stages, a ball starts in wire or rod form. Quality control goes through a metallurgic testing to ensure that the material composition is within acceptable ranges. |
Heading | After the raw material has passed inspection, it is then fed through a high speed header. This forms very rough balls. |
Flashing | The flashing process cleans up the headed balls so that they are somewhat smooth in appearance. |
Heat Treatment | An extremely high temperature process where the flashed balls are placed in an industrial oven. This hardens the ball. |
Grinding | The ball is ground to the approximately diameter of the final ball size. |
Lapping | The lapping of the ball brings it to it's desired final dimension. This is the final forming process and gets the ball within grade tolerances. |
Final Inspection | The ball is then precisely measured and inspected by Quality Control to ensure the highest quality. |
Packing | Wooden box Steel drum Nylon bag |
