The Screw Bounce Mystery Solved? One AIM Instructor’s Unexpected Discovery

David Hoffman, the director of Beaumont‘s American Injection Molding (AIM) Institute, recently published his research on Screw Bounce in Plastics Technology magazine!

But shortly after a student in AIM’s hands-on Molders’ Series course asked a seemingly unrelated question about a more precise calculation of shot size and transfer position settings, Hoffman and his team initiated research that ultimately led to a new understanding of screw bounce and how it actually affects the calculations that the student was referring to.
