As Manufacturing Engineer at Ford Motor Company I have worked with Kruse Analysis for several years and rely on Torsten for his experience and insight. The Kruse Training program takes what Torsten has learned in his years in the injection molding industry and helps new and veteran engineers expand their knowledge and become more well-rounded professionals.
Jeff Kloberdanz, Ford Motor Company

The Circle of Knowledge program highlights the key areas of molding fundamentals, materials, part, mold design, as well as processing. The Kruse Training program is a first-class training program and I look forward to continuing my plastics education with the Kruse Training team!
Michael Dalrymple, ALBA Enterprises

We have been using the Kruse Training program at Prestige Mold since it launched in 2018. I have worked closely with Torsten to ensure the content and delivery of the training materials meets our needs and am pleased with the results for our engineering group and the company overall.
Clinton Stark, Prestige Mold

I was able to do it from work, at my own pace. The graphics are excellent. The content was well thought out as it took me through the steps, from the very basic to advanced molding. I learned things that I never knew before.
Roger Sawyer, Aroplax Corporation
