Straight answers for people who buy precision machining, molds and thermal optics — written by the engineers who quote and build the parts, not by a marketing team.
Practical, numbers-first reads for sourcing managers and design engineers.
Blanket tolerances, missing DFM reviews, price-only awards — the ten errors that quietly inflate cost and lead time, and what to do instead.
