> using molds that cost $650,000, at a specialty machine shop Just because the mold was really expensive doesn't mean that the marginal cost of each unit created by it is more than a unit produced by a cheap mold. In many cases, the marginal cost is significantly less as you are able to use less raw material thanks to variable thicknesses, etc. There's a break-even point where the expensive mold becomes cheaper/better and that's another area where experienced manufacturing consultants help out.
