Look here ! Will not go well, my background is in sand casting.

Yes, I know it won’t work for full production but will if effect the price of the quote? I just need a approximate quote and not to have it manufacture ready.

Why spend money on “not a good design” ? ? ?

Not spending any money, just want a quote. I want to know if the quote will be better, if draft is slightly better. Parts are designed to be plastic injected molded right now, but they aren’t perfect.

I should have the person giving you the quote ! They have to spend money and time.

This is not wasting anyone’s time. We need to determine the approximate cost in order to refine the product and design. This is something that contract manufacturers do all the time.

I ‘d be yelled for asking the vendor to give quote for a “napkin drawing”, if you want costs between $30,000 to $45,000 just get a verbal ballpark or e-mail rather than a quote.

These are not napkin drawings, these are engineered CAD files. I am a mechanical engineer and I know how to properly design plastic parts. I would expect that the contract manufacturer has a program that they could input the CAD files into in order to get a quote, so not that much work. I just want to know if the quote changes if they have more acceptable draft. You aren’t really answering the question.

I would caveat the RFQ with a note asking them to quote on this preliminary design, and that the final design would have drafts in additional new areas. Major dimensions would remain the same. Also, you could ask them for suggestions for reducing mold cost.
