What Our Clients Say

  • “Your numbers look really good and both lead times are very impressive on both new drives quoted. I have to compliment you guys on a great job, it is appreciated and nice to see a company go the extra mile for a customer. Thanks to you all!”
  • “Kudus to you guys for getting two of those DB420 cards back to us so quickly. Our machine was back up and running perfectly!”
  • “Thanks for getting our machine going. We're extremely happy! I am glad your company was able to shine on this one.”
  • “In regards to the Magswitch Actuator your shop repaired for us. As for my understanding your tech spent time on it and determined that it was still under the OEM warranty. Doing so, it saved us money in the long run. I am confident that I can recommend ACT for ethics, quality work and high standards in their field.”
  • “We will definitely keep ACT in mind when we may need future repairs and/or maintenance on our presses and equipment. Dan did a great job for us. I know that the repair job was not an easy diagnosis and fix, but we were very pleased with the outcome once Dan was done. It was somewhat difficult finding a quality repair outfit at reasonable pricing. We would definitely recommend ACT to any other companies in our shoes. In fact, if you would like a customer testimonial from us, I would be happy to oblige.”
  • “ACT has been a great resource for the Dover products plant. The communication is clear and consistent, the lead times are accurate, and the quality is as well. It has been a pleasure doing work with ACT and will continue to be.”
  • “Recently Automation Control Technologies performed a rush turnaround repair on a Pathfinder controller for a Van Dorn injection molding machine for us at TH Plastics Inc. Our injection molding machine was down with no back up parts for this controller that is no longer supported by the manufacturer. The Team at ACT picked up the malfunctioning OP station at our plant in Michigan, delivered it to the repair facilities in Ohio, repaired it and rushed it back to us to get our machine running production in a two day time span.”
  • “I would like to say thank you for all your help with our brake resistor module Monday, it is nice to know we have people who we can count on.”
  • “My experience with both the salesperson and their shop repairs is positive. Both groups are very concerned to resolve any quality, delivery, and cost issues. As long as the key metrics of cost, delivery and quality continue at the positive level, we will continue to have a strong business relationship in the future.”
  • “We got the drive last night... installed and running without issue by 5:30PM. You and your team did a fantastic job!! Thank you!!”
