“It’s been my great privilege to work with the folks at Diemaster on several injection mold projects. Their attention to detail and resultant quality of product is outstanding. They stand behind their work and their support is awesome.”
— Jim Penson, Tool Engineer, B&N Precision
“My experiences with Diemaster are terrific from start to finish. They always show clear attention to detail, deliver on time, and never any fuss. Excellent communicators along the way including in-process photos and status updates. It is clear to me they care deeply about doing things right. Impressive company.”
— Dave Spitzer, Project Manager, Eagle Flight Research Center
“I think the thing that most stands out to me is the amount of pride that they take in their work over at Diemaster, it’s uncommon to see anyone in most industries stand behind their work the way that Diemaster does and that makes a really big difference. Every phone conversation, teams meeting, and email interaction is always straightforward, honest, and purposeful while simultaneously being pleasant and productive. Working with Diemaster has allowed me to become a more effective employee in my own regard because the projects that we have going with them aren’t projects that I ever feel the need to keep constant tabs on, they will go out of their way to communicate something to you even during your own off hours so that you always have information that’s vital to the project. All in all you really get the feeling of working shoulder to shoulder with someone which is a tough thing to find in my opinion.”
