If your production process is just "stamping" and you are selling the pressed part to your automotive customer without any further action, you can apply for IATF certification. Your scope would be "Manufacturing of stamped parts" if product design excluded.
If you have welding and assembly processes in your automotive product other than the stamping process, then the welding and assembly processes must also be audited under IATF certification.
If you have welding and assembly processes within the scope of ISO 9001 and "stamping" is only within the scope of automotive; Even if your scope is ‘’ manufacturing of stamped parts’’ because production processes cannot be separated according to IATF rules and they are all in the same factory; welding and assembly processes must also be audited.
In the case of this situation I have mentioned, 3 different actions can be taken in accordance with IATF rules:
1) The automotive process can be moved to another building. Or
2) The "stamping" process is separated by a separate wall inside the building; its door must be separate, its operators must be separate and it must not work for anyone other than automotive. In case of a 2nd case, as this issue is risky for IATFyou should make a detailed application to your certification company. Or
3) All production processes must be audited in the same building, but your certification scope is "manufacturing of stamped parts".
