Sourcing GuidesDuplication projects fail when buyers use visual approval only. You need dimensional tolerances, stack behavior targets, and weight windows.
These metrics should be captured before mold production begins.
Use a staged sequence: tooling sample, fired sample, and service test sample. Each stage should have written acceptance criteria.
Skipping stages can save days upfront but usually creates rework after production starts.
Once approved, references should be archived with production notes. This protects long-term replenishment and reduces drift over time.
Reference discipline is the difference between one successful shipment and a sustainable sourcing program.
Initial duplication and fired counter-sample approval often takes around 20-30 days.
Exact parity is constrained by process differences, but high-fidelity matching is achievable with proper controls.
Insufficient technical tolerance definition before mold and sample stages.
