Graham Engineering Company has earned its reputation for flexibility, attention to detail, follow-through, and delivering what we promise, on time. No matter what extrusion need you have, our systems are customized to your requirements. We are adept at navigating your complicated needs, listening, and collaborating. However, you do not have to take our word for it. Here are just a few of our customer’s opinions on what it’s like to work with Graham.

"[Graham Engineering Company] listened to what we said we needed. But the real reason we’d buy from them again is the way they worked with us every step of the way to make sure the line did what they said it would do. You never really know how good your supplier is until they rise to a challenge. When they pull out all the stops to deliver the required results, that’s a good supplier. We hold ourselves to that standard as well." ~Bill J. Burke Jr., general manager Impact Plastics

“We spent an enormous amount of time researching plastics processing equipment suppliers and chose Graham Engineering because of their technical capabilities, their engineering and design support, and their Converge CTS [Conical Twin Screw] technology, which is more compact and streamlined in comparison with conventional twin-screw systems." ~ Joseph Ross co-CEO of rPlanet Earth

“One of our cornerstones is quality -- quality in everything we do. This includes who we interact with, who we purchase from, and the partners with whom we choose to do business. Graham Engineering has proven to be one of those quality partners.” - Jeff Atwood, President of Copperhead Industries

“We are very excited to partner with globally-recognized extrusion innovator Graham Engineering Company. American Kuhne silicone extruders are the most advanced on the market today." ~ Bob Waitt, marketing manager for Bluestar Silicones’s U.S. medical market

“With the Pro Ex team’s decades of experience in equipment selection and commissioning, we were very confident in the selection of our new Welex line. The design features, the team’s willingness to customize to our unique needs, and their reputation and commitment to customer service led to our selection.” ~Pro Ex co-owner and president Gary Borge

“Our goal is to provide robust, innovative solutions from the blow molding process that allow our customers to drive their overall cost down. We are already providing various fuel and hydraulic tanks with complex shapes, multiple ports and assemblies that are used in demanding construction and agricultural applications. Graham Engineering’s spiral flow diverter design helps support the BMS goal of continuing to improve throughput.” ~BMS President Doug von Arb
