Client Review: Aerospace

“Within these past 12 weeks: We finalized the design, finished/released drawings, surveyed vendors, chose vendors, cut PO’s, made changes along the way, received parts, assembled 1 unit, ran a handful of successful validation tests and wrote a final report; All completed by the deadline. I want to thank you (Roncelli Plastics) and your team for working with us to make this seemingly impossible task, a success."
