Most RFQ delays start before the supplier opens the files. Missing parting-line expectations, unclear resin choice and incomplete annual volume targets all force the toolmaker to guess. That usually means the quote comes back slower and with more conditions attached.
Before sending your RFQ, confirm resin family, cosmetic surfaces, target cavitation, machine limits and whether product assembly features are already frozen. If any of these points are still open, say so clearly in the request instead of leaving the toolmaker to infer them.
A practical DFM report should reduce risk, not create more questions. The more complete your starting package is, the faster the engineering discussion becomes.
