Short answer: A DFM checklist before injection molding helps founders catch geometry, material, tolerance, tooling, assembly and quality risks before the mold is cut.
What to check first
- Part function and load requirements
- Wall thickness and material choice
- Draft angles, ribs, bosses and undercuts
- Assembly method and fastener strategy
- Cosmetic surface requirements
- Expected production volume and quality standard
Why it matters
Most expensive injection molding problems are created before tooling starts. A structured DFM review turns unclear assumptions into specific design, mold and process decisions.
