Design for Manufacturability Analysis
Design for Manufacturability (DFM) is an engineering review process that evaluates a molded part’s geometry for potential manufacturing problems before tooling is built. DFM analysis identifies issues with wall thickness, draft angles, undercuts, parting line location, gate placement, shrinkage, and tolerance requirements — the kind of problems that can cause costly tooling rework, production quality issues, and program delays when discovered after steel has been cut.
At Brown Tool & Mold, our engineers perform a basic DFM review on every program we quote — reviewing your part model in NX CAD and documenting any moldability concerns before design begins. For complex programs, Moldex3D mold flow simulation is used to validate fill behavior, cooling performance, and warpage predictions before any machining begins.
DFM is not a separate service at BTM — it is a standard part of how we approach every tooling program. The goal is to identify and resolve design issues at the stage where changes are fast and inexpensive, not after the mold has been built.
