Capability
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.

Mold Flow Analysis before tooling commitment
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.

Output of the review
Flow-risk notes, gate suggestions, material and wall-thickness questions, and whether a deeper simulation should be scoped before build.
Review workflow
| Step | What happens |
|---|---|
| Assumption setup | Confirm resin, wall ranges, visible surfaces, likely gate areas and what the flow review must decide. |
| Filling review | Compare fill path, pressure, hesitation, air traps and weld-line positions against part function and appearance. |
| Shrink and warp discussion | Flag geometry and material conditions that can distort fit, flatness or cosmetic surfaces. |
| Tooling recommendation | Suggest gate options, venting focus, wall changes or whether deeper simulation is justified before build. |
Risk signals to flag early
Long thin flow paths are combined with tight appearance or flatness requirements.Weld lines land on clips, hinges, transparent faces or load-bearing areas.The buyer chooses gate location only by hidden surface convenience.Warpage risk is ignored until assembly gaps appear at T1.
Decision gate
The review should decide whether normal DFM is enough, whether gate or wall changes are needed, or whether formal simulation should be scoped before steel is cut.
