Most injection molding problems are discovered after the mold has already been built.

Sink marks, warpage, weak snap-fits, assembly interference, difficult ejection, excessive tooling complexity, and costly mold modifications are often caused by design decisions that looked acceptable in CAD but created problems during manufacturing.

I help companies identify those risks before tooling release.

This review goes beyond basic draft-angle checks. I evaluate the design from a manufacturing and tooling perspective, focusing on how part geometry will affect mold construction, molding stability, assembly performance, production quality, lead time, and overall manufacturing cost.

Typical review areas include:

• Wall thickness strategy and material flow • Draft angles and mold release • Rib, boss, and snap-fit design • Parting line and mold split feasibility • Undercuts and tooling complexity • Sink mark and warpage risks • Gate location considerations • Tolerance and assembly concerns • Production and tooling risk assessment

Deliverables:

• Detailed DFM review report • Identified manufacturing and tooling risks • Recommended design improvements • Production readiness assessment

My background includes production injection molding programs, multi-cavity mold development, mold flow analysis, tooling design, and manufacturing support. Recommendations are based on real production experience and the practical realities of mold manufacturing.

The goal is simple: identify expensive problems before steel is cut.
