How to Make It in America: Designing a Better Supply Chain for the 2nd-Generation Cuppow
With thermoforming I think that the per part cost is greater than the high-volume injection molding, but probably around the same price as low-volume molding. I don't think that the quality of parts is as good as injection molding, and and the yield probably is not as good (with injection molding, once our tools are running we are getting 100% usable good parts, with no secondary operations required for finishing). I could be wrong about some of this.

I'm definitely going to try that with a mixer.
@Pericles - Originally we had designed this product to be either thermoformed plastic or hydroformed metal, but low-volume injection molding tooling is pretty cheap so we went with that. The downside of the low-volume injection molding is that the per part price is about 10x more expensive, and the quantity of scale price breaks plateau at about 5k pieces.
