They are checked for visual defects, weight consistency, and dimensional accuracy. This step is not merely about smoothing the surface; it is a critical calibration process that ensures the balls are perfectly round and meet the strict tolerance levels required for professional play.
Pool Ball Hardness And Impact Resistance During Manufacturing
In this method, liquid resin is poured into a spinning mold. When the molds close, they exert pressure up to several tons per square inch.
This pressure forces the material to fill every corner of the mold cavity while simultaneously curing the polymer matrix, resulting in a seamless, solid sphere. Two hemispherical molds are used, and the compounded resin is loaded inside.

This compounding phase is critical for achieving the final physical properties of the ball, such as impact resistance and surface hardness. The journey from raw compound to a perfectly balanced sphere is one of meticulous process control.
