What we see from Detroit

Detroit is built on automotive assembly and the tier-one and tier-two supplier base around it — stamping presses, transfer lines, weld cells and machining centers, an environment where servo drives and HMIs work hard and downtime is measured against line rate. That mix decides which controls end up on our bench: automotive, stamping, machining and tier suppliers all depend on operator terminals, drives and power supplies that reach end of life long before the machines they run.

With roughly 2 business days of ground transit each way and 3–5 business days on the bench, most Detroit customers are back in production well inside the lead time quoted on a replacement unit. When a line is down, overnight shipping plus rush service compresses that further.

We are not a local depot in Detroit and do not pretend to be — this is a mail-in service run from a single bench lab in Arlington, Texas. What that buys you is a technician who repairs these units every day rather than one who sees one occasionally, and the same 24-month warranty wherever you ship from.

Part numbers we repair for Detroit customers

VFD Repair (ABB, Yaskawa, Danfoss & More) in Detroit — common questions

Can Michigan plants set up a commercial account?

Yes — maintenance teams and integrators in Michigan can open a commercial account for PO acceptance, priority queue, and repair history by serial. It's the same published pricing, with less friction on every subsequent repair.

Is my program safe shipping it out of state?

Yes. Applications and parameters live in the unit's protected memory, which our physical repairs never touch — and units are logged, photographed, and tracked by RMA from arrival to return shipment.

How long does shipping take from Michigan?

Ground transit from Michigan to our Dallas–Fort Worth lab typically runs 2–3 business days each way. With 3–5 business days on the bench, most Michigan customers have their repaired unit back inside two weeks — and overnight shipping plus rush service compresses that to days when a machine is down.
