Frequently Asked Questions
What types of automotive and EV parts can you manufacture?
Submit housings, brackets, flanges, spacers, covers and other drawing-defined metal or plastic components. For custom EV components, identify the mechanical interfaces, material and acceptance requirements; installed-system validation remains a separate responsibility.
Can you support prototypes and repeat production?
For automotive prototype machining, identify whether you need a fit model or a functional sample. Approve the drawing revision, material, finish and inspection scope before moving to repeat orders.
What should you send for a quote, and can you request an NDA?
For automotive CNC machining services, provide CAD and a dimensioned drawing, revision, material, finish, quantities and target date. Mark critical fits and required records. Request an NDA before sharing confidential project information.
Can you specify U.S. and European material grades?
Use the exact specification, grade, temper and product form. EN AW-6061, EN AW-6082 and EN AW-7075 are separate alloys. Confirm any substitution and certificate requirement before release.
Which inspection documents can your order include?
Specify the critical dimensions, material records, FAI and any customer-specific PPAP elements during quotation. The agreed document package does not replace your installed-assembly or vehicle-level validation.
How are minimum quantity, lead time and delivery confirmed?
Send your sample quantity and repeat-demand forecast for review. Material availability, geometry, tooling, finishing, inspection and shipping affect the quote. Confirm the schedule, packing and delivery terms for your specific order.
