Final material, temper, filler, coating thickness, color, gloss and protected interfaces are confirmed against the drawing and supplier data sheet.
Vehicle Development
From Drawing Review to Production Transfer
Automotive component development engineers can review critical interfaces, validation needs and production risks before prototype approval or repeat production.
DFM & Risk Review
Check datums, tolerances, thin features, tool access and assembly interfaces.
시제품 검증
Build representative parts for fit, function and design verification.
Process Approval
Confirm material, routing, finishing and inspection requirements.
변경 관리
Freeze the approved drawing, program and inspection plan for repeat orders.

자동차 제조 FAQ
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.
