自動車製造に関するよくある質問
Plan Your Automotive Project
What should automotive parts buyers send for a quotation?
Send the 3D model, dimensioned drawing, material, quantity, finish, inspection level and delivery target.
Can automotive prototypes be transferred to repeat production?
Yes. Approved drawings, programs, process routes and inspection requirements are controlled before repeat orders.
When should PPAP or additional quality records be requested?
Define the submission level and required records before quotation so documentation, samples and inspection work are included in the plan.
How can automotive part cost and lead time be reduced?
Use available materials, functional tolerances, standard finishes and geometry that reduces setups and special tooling.
How are drawing revisions handled during development?
Each approved change should update the drawing revision, affected process documents and inspection requirements before production continues.
