The resin is compounded with specific catalysts and pigments to achieve the characteristic look and feel, ensuring that every ball sinks to the same weight specification of approximately 5. 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.

Mixing and Compounding Before molding can occur, the base phenolic resin is blended with a precise mixture of curing agents and colorants. Buffing and lapping machines use abrasive compounds to shave off microscopic layers of material.
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 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.
