What DFM Flags Mean on an Instant Quote
What Is a DFM Flag on an Instant Quote?
Searchers look up what dfm flags mean on an instant quote when a yellow or red note appears next to the first number. A DFM flag is an early manufacturability note tied to the CAD and RFQ you sent. It marks a geometry, finish, or requirement that needs a decision before tooling release.
It is not a refusal to quote and it is not a final steel instruction. For the review program, read injection molding DFM review before tooling. For the design-guide view, read injection molding DFM design guide. This page only explains flags on the quote.
Key Facts
- Flags come from geometry plus the requirements you typed.
- A flag asks you to change the solid, change a note, or accept a risk.
- Reviewers confirm flags before tooling release on scoped programs.
- A flag can move the next quote if the steel scope changes. Read why instant quote changes after CAD review.
- No wall, draft, rib, or gate numbers appear as NetProto specifications.
- See injection molding DFM design guide for the design-side list.
- Upload the next package on the injection molding instant quote platform.
Common Flag Classes
Name the class when you write the decision. Looks fine is not a decision. Accept section risk on the logo boss is.
Release class: draft, texture, shutoff the solid does not show
The part may still pull. The face may scuff, or the tool may need a different split. Write whether you will add draft, drop the grain, change the shutoff, or accept scuff on a named face.
Section class: local mass that will sink or warp
The note is about the solid, not about a press recipe. A thick boss, a heavy rib root, or a sudden wall jump can raise this class. Write whether you will core the mass, move the feature, or accept sink or warp on that face.
Action class: slide, lifter, side-action the first click treated as simple pull
The first click may treat the solid as a simple pull. A keep-out, hook, or undercut that needs a slide or lifter is an action class. Steel scope can change. Write whether you will remove the undercut or accept the action on that feature.
Requirement class: tolerance or finish the RFQ asked on a face that cannot hold it
The geometry may be fine. The note on the RFQ is the problem. A tight band or a show-face grain on a face that cannot hold it is a requirement class. Write whether you will loosen the band, move the finish, or change the face.
What a Flag Is Not
Not a we will not mold this message
A flag is a decision, not a stop. Many flagged faces can still mold after a section change, a looser note, or an accepted cosmetic risk. Read the flag against a named face before you abandon the quote.
Not a press recipe
A flag does not set fill speed, pack, or cooling. Do not treat it as a process card. It is a manufacturability note on the solid and the RFQ.
Not a reason to add a second tool product
A flag is not a request to add a second tool product. One hardened steel tool remains the path. The flag is about the solid and the notes on that tool. If the drawing and the flag disagree, write which document wins on that face.
RFQ Checklist
Numbered steps:
- Read each flag against a named face or feature.
- Mark accept, change CAD, or change the requirement.
- Keep the same revision ID if you only change notes.
- Follow what to do when DFM flags your part for the next upload.
- Upload CAD through the injection molding instant quote platform.
If you skip step 2, the next upload is the same argument. Reviewers cannot confirm a decision you did not write.
A Worked Example
The first click flags a tall textured wall and a logo boss. The textured wall is a release class. The logo boss is a section class. Those are two decisions.
On the wall, the team can add draft, drop the grain, or accept scuff risk on a non-show face. Write one of those three. On the boss, they can core the mass, move the logo, or accept a sink on a face that will be painted. Write one of those three. Then upload. A single note that says we will look at DFM does not close either flag.
If the next quote moves, ask which decision changed steel scope. Accepting scuff on a non-show face may leave both lines still. Adding a slide to save a texture on a show face may not. That is why instant quote changes after CAD review.
Common Mistakes
Reading a flag as a hard no and abandoning the portal. Most flags are decisions, not refusals. A flag is a decision, not a stop.
Accepting every flag without reading the face. Reviewers will still ask which face you accepted.
Changing CAD and the RFQ requirement on the same flag, then asking why the delta is large. Isolate one decision per re-quote when you can.
Replying to a flag in chat and never writing it on the quote record. The next reviewer will raise the same note.
What to Tell Sourcing
A flag is a decision, not a stop. The quote remains open. The next package must carry accept, CAD change, or requirement change on each named face.
If they want to know whether the number will move, the honest answer is: it moves when the decision changes steel scope. Accepting a cosmetic risk on a non-show face may not. Adding an action to save a show-face grain may.
Do not ask them to ignore a flag because the first click already existed. That click was tied to an unanswered note.
Send the next upload through the same platform so the flag and the decision live on one record.
