Slim Haney Machining to Mark 10th Anniversary of its Facility

Tulsa-based manufacturer Slim Haney Machining is hosting a “ribbon cutting” to mark the 10th anniversary of its facility. Festivities will kick off Aug. 3 at 10 a.m. The ribbon cutting will be followed by plant tours.

Slim Haney is a multi-spindle/CNC production machine shop that has operated in Oklahoma for nearly 55 years. In 1962 W.B. Haney—who everyone called Slim—started the company in his garage. In 1970, Haney relocated operations to a storage unit on south 99th E. Ave in Tulsa. At that point Haney’s son Gene joined the company along with Bob Parrott.

In 1985, the elder Haney retired and sold the business to Gene, who organized and implemented a CNC department. Parrott was promoted and his work helped double production. In 2004 Newton Box, who had a long working relationship with Haney, officially became the owner while Parrott became VP. Ten years ago, Slim Haney Machining relocated to a climate controlled 20,000 square-foot facility that sits on 3 acres at the corner of 5615 North Mingo in Tulsa.

In 2011 Slim Haney topped $6 million in sales. In 2012 it became ISO certified and is projecting to break the $10 million sales mark this year.

“The company has embraced Lean Manufacturing concepts and we are a big believer in the 6S environment,” says Colin Jones, the sales manager who oversees who oversees safety, 5S program, continuing ISO requirements, and Lean efforts. “We worked extremely hard to get our facility where it is now and know we still have a long way to go. I will say if you stop in and look at our facility you will not be disappointed. We encourage everyone to join the celebration on Aug. 3—especially local manufacturers.”
