Make the drawing revision and approval process explicit

Send a dimensioned drawing with tolerances, units, material requirements, surface requirements and a revision identifier. Mark critical dimensions and explain the application and mating components.

Ask the quotation to separate tooling, samples and production quantities. Confirm tooling ownership, maintenance responsibility, expected approval stages and the handling of later drawing changes in writing.

Require the supplier to identify any proposed deviations before tooling starts. Define the sample measurement report and functional checks needed for written production approval.

Certification, parameters and delivery

Ask for current certificates relevant to the manufacturing site and your purchasing requirements. Verify the document number, scope and validity. Match inspection records to the part and lot specified in your order.

State the dimensions, compound requirements and operating conditions you need confirmed. Request separate sample and production schedules, including the approval trigger, dispatch date and destination. VKEFOT certification availability, MOQ and delivery dates must be confirmed in the quotation for your selected part.
