DFM Review
Review part geometry before mold steel is cut: wall thickness, draft, ribs, bosses, undercuts, gate location, parting line, ejection, cooling, tolerance and cosmetic risk.

Review workflow
| Step | What happens |
|---|---|
| File intake | Check CAD, drawing, resin, finish, quantity, cosmetic zones and current project stage. |
| Geometry pass | Review wall thickness, draft, ribs, bosses, undercuts, snap fits, inserts and assembly interfaces. |
| Tooling assumption pass | Map likely parting line, gates, ejection, cooling, sliders, lifters, steel-safe areas and tolerance risks. |
| Decision report | Separate must-change geometry, optional improvements, quote assumptions and sample acceptance questions. |
Risk signals to flag early
No resin, finish or critical dimensions are attached to CAD.Cosmetic surfaces are not marked before gate and parting-line review.Draft is missing on textured or deep wall features.Undercuts are hidden in product details but not priced as side actions.
Decision gate
A good DFM review should tell the buyer whether CAD is ready for mold quotation, needs design changes, or requires a higher-risk tooling strategy that should be approved explicitly.
What to prepare
3D CAD or 2D drawingTarget resin and colorEstimated first order and annual volumeCritical dimensions and cosmetic surfacesCurrent sample photos or defects if available
Where this fits in the station group
| Stage | Best next action |
|---|---|
| Concept or CAD is unstable | Start with industrial design or CAD cleanup. |
| CAD is ready for mold review | Request ToolingPilot tooling review. |
| T1 samples are approved | Move into injection molding production. |
