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
Early in design. Before tooling. Before quoting. We provide free DFM review with quote.
Typical 20-50% cost reduction. Sometimes more for poorly DFMed designs.
Tight tolerances 5-10× cost premium. Loosening saves significantly.
40-70% material cost savings often possible. Without function loss.
Generous radii enable larger tools. 2-3× cycle time reduction.
Custom drives tooling cost. Standard threads, fasteners, sizes always cheaper.
