What Our Customers Say

  • "We have built many tools over the years with several different shops, but none can compare to the one your facility just finished. The workmanship is beyond reproach, the engineering was brilliant and the customer service was exceptional."

  • "Just wanted to give you and your team a huge thanks on the completion of the hood guide tool. You really went above and beyond providing multiple project updates weekly and including pictures. Not only did you build a good tool you delivered early and we certainly needed that extra time."

  • "Please thank the guys in the shop for a great job on our mold. It’s not often that you get a part on the first shot and don’t have to go back to the press for corrections. I know it wasn’t the most difficult tool you have built but it’s the simple ones always seem to sneak up and bite you. Good job to all."

  • "Please extend our gratitude to the MSI team for building two great molds that ran right out of the gate!"

  • "I just wanted to take a moment to thank you and your team for the great job that was done on all of our molds for the GLC project. All of the initial mold trials were successfully completed and were problem free."

  • "I just wanted to take a few moments to thank you and all the designers and toolmakers for the extraordinary hard work that was put in on the AxSYM tooling program.  With your help we have successfully completed 28 structure and skin tools and delivered production part to the line on schedule.  This could not have been completed without the extra effort and long hours that were put in on this project.  Again, I thank you and hope we will have opportunity to work together again."
