Frequently Asked Questions

Can you quote steel parts with heat treatment included?

Yes, we quote the full route: machining, treatment at audited partners, finishing and certificates, as one order with one point of accountability.

What is your minimum order on steel parts?

No MOQ. Fixture and die components often run in single pieces or small sets; production families run in repeat batches.

Do you plate or coat steel parts after machining?

Zinc, nickel and black oxide are coordinated per drawing with RoHS and REACH declarations available.
