Moldings represent a very large investment, both monetary and in time.

You will need to machine a mold for your wheel. This is not simple, and will cost a LOT of money for you to have a shop make (Likely more time than if you just CNC machined however many wheels you want to make).

You'll then need someone to injection mold your wheels. This will also be quite expensive.

Molding is really not something you do for onesies and twosies. If you're getting something injection molded, you're making thousands of them. Any less, and you cannot justify the cost involved.
