I should have clarified - the part needs a MINIMUM of 2% stretch. But it turns out that is not enough. 2% is sufficient for a bicycle wheel but not a motorcycle wheel due to the taller rim flange. In reality it needs closer to 10%.
We tried a 3D printed polypropylene prototype and it broke...
About 40,000 pieces per year.
This part does not need to "stick" to anything. It stays in place because it's diameter is slightly less than the wheel's. That's why the material requires a minimum 2% stretch without damage.
Thanks for the reply.
It's not a rim. It's a flexible element that lines the rim. It's not a structural part.
Polypropylene is my best guess. It's very tough, but flexible and elastic. Does that help?
Hi,
First time poster - hope this isn't off base.
I'm looking for a manufacturer for the product pictured below. I need to know what TYPE of manufacturing methods could be used to make this part (injection molding, extrusion, thermoforming, etc.)
It is about 21" (533mm) in diameter and about...
