What buyers say about working with Proco

“Proco built our chassis from a handful of pilot units to full production without us redrawing a thing, and the fit and finish made our product look like it belonged in a data center. Their team caught tolerance issues on our early drawings that would have cost us a spin. As a startup, having a supplier who scales with you and watches your back is genuinely rare — we'd recommend them to any hardware team.”

“We're brewers, not sheet-metal engineers, and Proco met us there. They understood what a washdown does to a control panel, built the enclosures to our layout with all the cutouts and hardware done, and delivered them ready to wire. We haven't replaced a control cabinet since. When a supplier saves you from a problem you didn't know how to describe, you keep them.”

“Proco steered us to the right alloy for salt water when we'd have picked the wrong one to save a few dollars, and it saved our reputation. The castings come tumbled and polished to the finish our buyers expect, so what lands on our dock is ready to sell. They know their materials, they finish it properly, and they stand behind it. That's rare.”

“The best part of working with Proco is that the casting shows up finished — cast, machined, and powder-coated — ready to populate. We used to coordinate a foundry, a machine shop, and a coater ourselves and own every gap between them. Now it's one supplier, one lead time, one contact who owns the outcome. It took a whole layer of coordination off my desk.”

“We were juggling four fastener vendors and still getting caught short. Proco consolidated the whole bill of materials onto one PO with one point of contact, and our line stopped stalling for want of a nut. The coatings hold up to the road salt our customers drive through, and the paperwork is clean every time. Fewer suppliers, fewer headaches, better parts.”

“Proco set up a stocking program for our fasteners with scheduled releases, so the right parts show up when our build plan needs them and we're not tying up cash in a year of inventory. When we had a problem with tapped sheet, they recommended a better fastener instead of just selling us what we asked for. They act like a partner in our production, not a vending machine.”

“We machine small batches of precision dental components, and traceability isn't optional for us. Proco gives us material certs and lot control on every order, no matter how small, and the parts are consistent piece to piece. They've helped us hold our tolerances and our documentation standards without us having to build a huge supplier-quality team. That's exactly what a company our size needs.”

“What sold us was the first-article report. Proco sent back a full dimensional inspection before they ran a single production part, so we could design around numbers we trusted instead of hoping. Prototypes come in days, production holds the same tolerances, and their estimators actually flag things on our prints that will bite us later. It's like having a manufacturing engineer on staff.”

“We came to Proco as a tiny e-bike builder with a stamped motor bracket and low volumes nobody else wanted to touch. They tooled it anyway, held our delivery schedule as we scaled, and made it painless to move from a few hundred a month to a few thousand. They treated a small account like it mattered, and that's why we've never gone shopping.”

“Proco quotes come back in two days with real DFM notes, not just a number. Every lot ships with the certs already in the box, and in three years of orders they have never missed a promised date. For a shop our size, a supplier we don't have to chase is worth a premium — and they're not even charging one.”
