DFM checklist.
Manufacturability.
Cost optimization.
DFM checklist for manufacturability. Material selection, tolerance allocation, feature placement, surface finish. Standard checks before manufacturing.
Key principles.
Per cost/function
Cheapest material that meets requirements.
Per feature
Tight tolerance only on critical features.
Tool-friendly
Generous internal radii for tool clearance.
Process-appropriate
Per process minimum wall thickness.
Avoid custom
Standard hole sizes, threads, fasteners.
Match function
Specify per function. Don't over-spec.
FAQ
When to do DFM review?
Early in design. Before tooling. Before quoting. We provide free DFM review with quote.
Cost savings from DFM?
Typical 20-50% cost reduction. Sometimes more for poorly DFMed designs.
Tolerance audit savings?
Tight tolerances 5-10× cost premium. Loosening saves significantly.
Material substitution savings?
40-70% material cost savings often possible. Without function loss.
Internal radii savings?
Generous radii enable larger tools. 2-3× cycle time reduction.
Standard features importance?
Custom drives tooling cost. Standard threads, fasteners, sizes always cheaper.
