“In recent years, the term ‘scientific molding’ has become a buzzword of sorts,” wrote Garrett MacKenzie in one of his articles for PlasticsToday. “There are many organizations claiming to be scientific molders and trainers. Great care should be taken when choosing a training source for scientific molding theory and applications,” he cautioned. That’s sound advice that you should take to heart if you are shopping for a course in scientific molding. Do your research, check the credentials of the program instructor, ask your colleagues . . . or you could skip the due diligence and sign up for a scientific molding workshop led by MacKenzie himself. He is organizing a two-day workshop in Dalton, GA, on March 24 and 25, 2018, that truly lives up to the “hands-on training” tagline that many other courses promise. “This is not classroom training,” stresses MacKenzie. “Both days of training take place directly on the injection molding machine.”

Topics covered during the two-day program include:

Press, mold and auxiliary equipment validationCavity balance and historical dataDecoupled moldingDesign optimization experiments (DOE): Designing and implementing DOE experiments to improve process and production system performanceProcess monitoring and control: Differentiating between flexible and rigid process control limits. Attendees will learn how to gather historical molding data and make comparisons to current running conditionsScientific troubleshooting, including injection profilingFill time, gate seal, viscosity and back pressure studies

MacKenzie will also explain what injection molders can learn from NASCAR pit crews to minimize down time while increasing change-over consistencies to improve start-up capabilities.

Owner/editor of plastic411.com, as well as a consultant/trainer to the plastic injection industry, MacKenzie has spent more than 31 years in plastics processing, engineering and development. He has worked in the automotive sector for both U.S. and Japanese automotive OEMs and has experience in handgun manufacturing at Glock. He describes himself as a "strong supporter of the John Bozzelli methodology," and has worked using RJG E-Dart systems for many years. He currently offers a two-day training program, the Core Processor Training System, which is at-the-press training using the facility's own materials, controllers, processes and auxilliary equipment. In addition, he works as a Process Engineer for Ernie Green Industries, a Tier 1 supplier to Honda.
