Centrifugal Casting: An Alternative Method For higher-end or specialty balls, centrifugal casting offers an alternative that minimizes internal stress. Buffing and Lapping to Perfect Dimensions Polishing and Quality Control The final step involves a high-gloss polish that gives the balls their iconic shine and influences the speed of the game.
Modern Billiard Ball Production Line: From Raw Resin to Precision-Machined Spheres
The ingredients are mixed in industrial high-shear mixers to ensure a homogeneous distribution, eliminating streaks or weak spots that could affect performance during high-speed collisions. In this method, liquid resin is poured into a spinning mold.
Quality control technicians also test the balls for balance by spinning them on a fixed axis; any wobble indicates a deviation from the perfect sphere. Buffing and lapping machines use abrasive compounds to shave off microscopic layers of material.
