How Bowling Balls Are Made

We love reading about how things are made. It reminds us that there’s a whole world of manufacturing out there in factories and warehouses across America that we never get to see. So thanks to Utah TV station KSL for giving us a peek into how bowling balls are created.

The station published a photo essay taking us inside the Storm corporation in Brigham City. The firm has been producing bowling balls for over two decades, and also own the rights to the Master and Rotogrip brands. They make up to 3,000 balls every single day, and the process is pretty spectacular.

About 125 people work at Storm’s facility, handling every aspect of the business. It takes about three days from start to finish to make a bowling ball, and the process is intensive.

First, raw materials are mixed to create the weight blocks that rest at the core of each ball. These resins are heated to temperatures of 260 degrees. Interestingly, the cores aren’t simple spheres – different balls have different core shapes, which affect how they roll.

Those cores cool in molds and are then surrounded by packing material to create the bowling ball’s spherical form. The they go into another mold for the “coverstock,” the urethane coating that forms the ball’s durable outer shell. At Storm they also have a patent for scented bowling balls and can deliver from 11,000 different scents, including bacon.

Balls cool overnight and then are run through sanding and polishing machines to set their finish. Then they go through an engraving machine for logos and other details. Storm also has a testing facility on site where they put both their balls and competitors through their paces to make sure quality is high.
