What We Do

We get it. You’re pressured by manufacturers to supply the most accurate parts on time, every time. That’s why we’ve made it our job to help. Since 1998, Witness has offered reliable contract inspection services that reduce risk in the marketplace.

We partner with you to discover any issues with parts, recommend a solution, and ensure customer satisfaction. Whether it’s washing or finishing, inspection or packaging, make us your go-to provider today.

"Witness equipment is not only more effective than the human eye, but it’s also better than similar sorting technologies. We haven’t had any complaints from customers since we made them responsible for our parts."

Mark Drooger, Precision Metal Products

“For our customers, even one or two defective parts in a shipment of a million pieces is unacceptable. Since we started working with Witness, their performance has been phenomenal. We haven’t had a single problem, and the process has been highly versatile and extremely accurate.”

“With Witness, it’s more efficient and less expensive. Our parts are much more accurate, too. We’ve cut our labor costs by 80 percent and we haven't received a return or complaint on anything that they've done for us.”


“Out of 30 suppliers, one customer moved us up to number three after we started using Witness. They've helped us improve our customer relationships, so we recommended them to our own suppliers as well.”

Jim Schuster, Warmington Industries


From fully automated vision systems to visual inspection, to a hybrid of both, our expansive capabilities allow us to check a high volume of parts and solve every sorting challenge.


With numerous types of washing equipment and chemistries, we have the expertise and support to clean parts consistently and effectively.

Vibratory Finishing + Deburring

Offering extreme flexibility and multiple media options, our process makes it easy to achieve a uniform surface finish.


We take time to understand your project needs and ask the tough questions. Our team will sit with you to discuss potential options, whether it's sending your product to our facility, bringing our machines to your shop floor, or simply offering advice on how to manage systems yourself. No matter the case, we're here to help.

Reporting + Data Collection

To learn why parts fail and identify defects, we provide stop/notify reports, quality alerts, and reject reports. It's our way of improving your manufacturing process and ensuring greater accuracy in the future.
