To achieve the signature two-tone or spotted appearance of many balls, a portion of this mixture is dyed a contrasting color. This material is chosen for its exceptional hardness, durability, and resistance to chipping and cracking under impact.
The Science of Durability: How Material Properties Shape Billiard Ball Performance
The colored and non-colored compounds are then loaded into a press in alternating layers, setting the stage for the core’s distinctive pattern. Following grinding, the balls undergo lapping, where they are tumbled with fine abrasive grit and a lubricant inside large rotating drums.
The press then applies thousands of pounds of force, compressing the material and simultaneously heating it to a specific temperature. This mixture is combined in precise ratios within a large industrial mixer, creating a thick, dough-like compound.
The Science Behind Material Composition and Layering Techniques
Precision Grinding and Lapping Once the core slug is ejected from the mold, it is far from its final shape. Each ball is measured for precise diameter and weight, and advanced systems use sensors to detect any internal flaws, inconsistencies in density, or imperfections in the outer shell that could affect gameplay.
