New Rapid Forge Design Article in FIA Magazine

Our Rapid Forge Design (RFD) software has generated a substantial amount of buzz since it’s release last year. If you’ve been keeping up with our social media accounts, you’ve probably caught us highlighting its key features and ease of use, especially through our demonstration video in which creator John Watton goes step-by-step through the closed-die impression forging design process.

For those who want a more comprehensive rundown of the software’s features and abilities, as well as plans for future design modules, John recently published an article in Forging Industry Association magazine, where he gives a history of how RFD came to be, and how it serves forgers and forging consumers.

In the Field with Ryan: On-site Residual Stress Measurements

While we at Hill Engineering take pride in our ability to perform high quality residual stress measurements in our laboratory, we recognize that not all parts and projects can be easily transported.

That’s where we bring the measurements to you with our Residual Stress Field Team. Our laboratory engineers are capable of performing residual stress measurements across the globe, and have done so on many occasions.
