without castings IN A WORLD


Would Skateboarders Be Grounded?


What began as a way for Southern


Californian surfers to practice when the waves weren’t cooperating, skate- boarding has grown to a $4.8 billion industry—an industry that quite literally rests on metal castings. T e skateboard’s wheels are attached to the deck (aka the


board) by two trucks, each consisting of a base plate and hang- er, which holds the axle. While some truck parts are forged or cast in permanent molds, many—especially for high-speed “longboards”—are cast in aluminum in green sand. Aluminum trucks minimize weight and provide the necessary strength and ductility to let skateboarders continue to push the limits. 
