Recent questions

• How did polyurethane wheels impact skateboarding?

  Polyurethane wheels revolutionized skateboarding in the 1970s by providing better grip, durability, and shock absorption compared to previous metal or ceramic wheels. This advancement allowed skateboarders to perform tricks and maneuvers more effectively, leading to the growth and evolution of the sport.

• What factors differentiate skateboard wheels?

  Skateboard wheels vary in size, hardness, colors, and designs, offering riders a range of options to suit their preferences and riding styles. Factors such as wheel diameter, durometer rating, and graphic designs play a crucial role in the performance and aesthetics of skateboard wheels.

• How are skateboard wheels manufactured?

  The manufacturing process of skateboard wheels begins with computer design and cutting tools shaping aluminum pucks into molds. Polyurethane liquid is then dispensed into the molds, solidifying quickly and baked at 115 degrees Celsius to ensure solidity. Workers remove the pins, release the wheels with compressed air, and test for rebound and hardness before adding graphic designs.

• What is the purpose of CO2 scrubbers in apple storage?

  CO2 scrubbers are used in apple storage to lower oxygen levels, extending the shelf life of the fruit by reducing the risk of spoilage. Workers construct these machines using tubular steel, carbon pellets, and vessels that alternate between scrubbing and regeneration cycles to maintain optimal storage conditions for apples.

• How do workers ensure the quality of skateboard wheels?

  After manufacturing, workers test skateboard wheels for rebound and hardness to ensure quality and performance. By conducting these tests, they can guarantee that the wheels meet the necessary standards for durability and functionality before adding graphic designs for aesthetic appeal.
