Who We Are
PLC Machinery is a family-owned industrial automation equipment supplier based in Austin, Texas. For over 20 years, we’ve helped manufacturers, engineers, and maintenance teams across the country keep their operations running by sourcing the quality surplus equipment they need — fast.
Family-Owned, Customer-Focused
Hi, I’m Cory Martin — founder of PLC Machinery. What started as a passion for industrial automation has grown into a business my whole family is proud of. We’re based in Austin, Texas, and every order that goes out the door has our name on it.
When you buy from us, you’re not dealing with a faceless warehouse. You’re working with real people who stand behind every part we sell.
What We Do
We specialize in quality-tested surplus PLCs, drives, motors, sensors, HMIs, and industrial components from the brands you trust: Allen-Bradley, Siemens, ABB, Schneider Electric, Eaton Cutler-Hammer, and more. With over 17,000 parts in our inventory, chances are we have exactly what you’re looking for.
Every piece of equipment we sell is inspected and tested before it ships. When you order from us, you’re not rolling the dice — you’re getting a part that works.
Why Buy Surplus?
Original equipment manufacturers discontinue parts. Lead times stretch. Budgets tighten. Surplus industrial equipment fills that gap — giving you access to hard-to-find components at a fraction of the new price, without the wait. We’ve built our business on making that process simple and trustworthy.
Fast Shipping, Real Support
We know downtime is expensive. That’s why we ship same-day on in-stock orders placed before 2:00 PM CST, with options for overnight and 2-day delivery when every hour counts. And when you have questions, you’re talking to people who know this equipment — not a call center script.
