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.
Capabilities
Tooling engineering capabilities before mold build.
Use DFM and mold flow review to make part and mold risk visible before steel, T1 samples and production handoff.
Capability routes
Engineering review should happen before tooling money is locked.
These capability pages help buyers ask for the right engineering review before committing tooling budget.
Mold Flow Analysis
Use mold flow review when geometry, appearance or resin behavior makes filling, weld lines, air traps, pressure, shrinkage or warpage difficult to judge from CAD alone.
Engineering review map
Make the invisible mold assumptions visible.
Capability pages explain not only the analysis name, but also the tooling decisions buyers are trying to de-risk.
| Capability question | What the buyer should receive |
|---|---|
| Will this part mold cleanly? | DFM notes covering wall transitions, draft, ribs, bosses, undercuts, gates, parting line and ejection. |
| Will the part fill and pack correctly? | Mold flow review of filling pattern, weld lines, air traps, pressure, shrinkage and warpage tendency. |
| Will cosmetics survive T1? | Surface-zone review for gate vestige, ejector marks, texture, polish, transparent parts and visible defects. |
| Will the quote assumptions hold? | A risk summary that connects geometry, material, steel, cavity count and T1 acceptance gates. |
When to use each capability
Not every project needs the same engineering depth.
The index page routes buyers to the right review before they ask only for price.
| Project signal | Best review path |
|---|---|
| New CAD with common plastic features | DFM review first. |
| Thin walls, long flow length or transparent cosmetic surfaces | Mold flow analysis or focused flow-risk review. |
| Existing T1 defects or supplier rescue | Mold rescue review with sample and trial evidence. |
| Approved T1 samples ready for production | Move to injection molding production. |
