The Reaction-Injection Molding of Steering Wheels

Published by Naseem Muaddi on November 28th, 2012

Lately, there’s been a lot of talk about wrapping steering wheels on The Hog Ring. In fact, community members JPM Coachworks and Gjudd published great tutorials in our Auto Upholstery Forum that demonstrate how to do it.

However, not all steering wheels get covered in leather. Some are coated in high-density foam rubber. For an explanation on how these steering wheels are made, check out this short video from Discovery Channel’s hit TV show “How It’s Made”.

Pay particular attention to the video’s explanation of reaction-injection molding, which starts at the 2:10 mark. It shows how automakers coat their steering wheels in foam, as well as the tools and materials they use to do it. Interesting stuff!

    This design is steller! You definitely know how to keep
    a reader amused. Between your wit and your videos, I was almost moved
    to start my own blog (well, almost…HaHa!) Great job.
    I really enjoyed what you had to say, and more than that, how you presented it.
    Too cool!
