Design for Manufacturability analysis and mold flow simulation are available as optional add-on services — for projects where you want to identify risks before tooling begins, not after.
Many molders include "DFM" as a checkbox in their process. We offer it as a genuine technical service for programs where the cost of tooling revisions or failed parts justifies the investment. For simple, well-defined parts with established materials, it adds cost without value.
| Analysis Area | What We Check | Why It Matters |
|---|---|---|
| Wall Thickness | Minimum/maximum, transition zones, sink mark risk areas | Thin sections cause short shots; thick sections cause sink marks and extended cycle time |
| Draft Angles | Per-surface draft analysis, zero-draft identification | Insufficient draft causes drag marks, part sticking, and dimensional distortion on ejection |
| Gate Location | Recommended gate position and type | Gate placement determines fill pattern, weld-line location, and fiber orientation |
| Weld Lines | Predicted locations and structural impact | Weld lines can reduce tensile strength by 10–30% — critical in structural applications |
| Air Traps | Potential entrapment zones requiring venting | Air traps cause burn marks, short shots, and surface defects |
| Tolerance Feasibility | CTQ dimensions assessed against material capability | Identifies features requiring tooling precision vs. process control |
| Material Compatibility | Resin selection confirmed against application requirements | Wrong material at design stage = tooling rework or product failure |
For programs that require mold flow simulation — fill analysis, warpage prediction, cooling optimization, fiber orientation modeling — we coordinate with qualified simulation partners using Autodesk Moldflow (preferred for EU/US clients) or Moldex3D.
Send us your drawings and describe your concerns. We'll tell you whether DFM analysis is justified for your program and provide a scope and timeline.
