Home / About
A rep agency that stays on the program.
Trinity Components Group has connected buyers with manufacturers since 2001. We're based in Metro Detroit, family-run, and we work the phone ourselves.
Who we are
We know the plants because we've walked them.
Trinity is a manufacturer's representative. We don't own a foundry or a machine shop. We represent a short list of North American plants we know well, and we bring them work they're set up to win.
For a buyer, that means one contact for castings, forgings, extrusions, powder metal, tubing and machining. You don't have to qualify six suppliers to find the one that fits. We've already done that work, and we know which plant is hungry for your part, which one has the right machine open, and which one shouldn't quote it at all.
For our partner plants, it means RFQs that fit their equipment and a rep who knows their capabilities as well as their own sales team does.
We stay on after the PO. Launch, PPAP, engineering changes, capacity questions and delivery issues all come through the same person who quoted the job.

How we work
Three things we don't compromise on.
Fit before volume
We only route a part to a plant that is built for it. A quote that never should have been sent wastes your time and theirs.
Straight answers
If a part isn't a fit for our network, we'll tell you on the first call. If a plant is behind, you'll hear it from us first.
Confidential by default
Prints, pricing and program details stay under NDA. We never share one customer's data with another.
The network
North American plants, automotive discipline.
Our partner plants are in the Great Lakes region and Mexico. Most hold IATF 16949, several hold ISO 14001, and machining capacity is ITAR registered.
