Does Anyone Do Injection Molding?

Hey, all. So, I've been gradually working on getting my GE 416 radio to as close to factory new cosmetic condition as possible. At this point, my main problem is the dial cover; it's dinged up beyond saving, not to mention most of the little plastic tabs holding it in place have broken apart. All that's holding it in place is a few dabs of super glue.

I tried going the parts cabinet route, but ended up spending money on a dial cover that was in more or less the same shape.

I'm hoping to get a new part made, now. A home injection molding machine is gonna run me something like 500 dollars, though, so I was wondering if anyone had the ability to, or knew of a service that can, injection mold a new, clear plastic dial cover from an old template.

I would suspect the custom mold itself would cost well more than the machine.

These are fairly common radios, I would think that you could find a donor set for much cheaper than having a custom part molded. Keep checking swap meets, CL, eBay...

Perhaps this one?

I saw that, but I really hate to pull parts from something in such good condition.

The replacement needed is a thick cast structure, not a thin dial cover.

I don't feel bad/guilty for using parts from 2 or 3 sets to put together one very nice one for my collection, particularly when fairly common sets are involved. Usually the second set can be sold to another collector, and the third (if used) may end up being a just parts set.

Just the tooling alone would be over a thousand bucks. A former landlord runs a plastic fab business, KayGee plastics. He has a couple of injection molds - he sends the actual molding out, but "owns" the molds for some helicopter parts, most in the square-foot area size, but he has two molds that create some 7" square covers out of ABS. His cost was nearly 3K for the two molds. Each injcction molding job requires a minimum of $1K, so I'd get the eBay radio - you can easily justify it in a cost-benefit analysis,,,,

Well that goes to show how much I know about injection molding. I've placed a bid on the radio.

Thanks, all.
