Many RFQ packages look complete on the surface but still carry DFM risks that show up later as added steel work, unstable molding or repeated T1 corrections. Common examples include missing draft, uneven wall thickness, undercuts without release strategy, deep ribs, poor gate access and unrealistic texture expectations near shut-off areas.
Buyers do not need to solve every tooling issue before contacting a supplier, but they do benefit from spotting the obvious risks early. If the part includes cosmetic Class A surfaces, snap fits, tight flatness requirements or thin sections, those conditions should be called out up front so the mold maker can review them intentionally instead of discovering them during design.
The best DFM discussion starts when both sides know where the risk sits. When you surface these red flags before RFQ, you shorten the clarification loop and get more useful feedback on gate location, ejection, cooling and mold complexity.
