ADAM PILLARD, BLACK RIVER FALLS, WISCONSIN: Hi, my name is Adam. I'm from Black River Falls, Wisconsin. And my question is: How are golf balls made?

BILL MORGAN, SENIOR VICE PRESIDENT R&D, TITLEIST GOLF BALLS: Golf balls are made using a variety of techniques that are common to both rubber and plastics processing. The three most popular techniques are compression molding, injection molding and casting.

To compression mold a golf ball, two half shells or cups of cover material are formed and assembled around the golf ball core. They're then placed into a hot mold where the cover material is melted so that it bonds to the core and the two cover halves are joined together. At the same time, the dimples are formed in the ball.

In injection molding, the core is placed in a cold mold and hot plastic is injected around the core.

The newest technique for making golf balls, casting, involves using two different liquids, which are then mixed together and then react to form a solid cover material. This liquid is poured or cast into open molds and then the core is carefully placed and centered inside the liquid material and held until the cover material forms a solid.
