I'm going to comment here too - on the RFQ's for my parts - I'm getting quite a range, even from one part to the other from the same company - i.e. company 1 has a good price for one part and is way way off for another. And keep in mind my parts are the same material. And I know what the material costs are for my parts because I have had to buy the material myself and I never made as many at one time as I am going to buy from my RFQ's.
Let's face it, on these jobs there's really only a few variables :
a) material cost
b) time needed to mill the parts (dependent on tooling, mill used, setups, skill levels)
c) basic shop rate (covers overhead)
If you look at my first RFQ, the material cost is pretty much insignificant - I pay as low as 12 cents for one of my #1 RFQ parts, altho I get a very good deal, figure even double that price and it's still way less than 10 percent of the total cost of the RFQ.
I would have thought that material cost would be the least variable of the costs, but that's not what I am seeing. It might be interesting to compare notes on some basic hypothetical part (in a new thread - don't mean to hijack this one) to see where the differences lie ?
