Background and Credentials

John is a graduate of Marietta College (BS) and Ohio University (MS). His studies were interrupted for a stint in Vietnam (Army First Air Calvary, Purple Heart & Silver Star). Twenty years in Dow Plastics provided image of John Bozzelliextensive experience in polymer synthesis, development, production, and processing. John has been a seminar leader with RJG Associates, Injection Molding Magazine, University of Wisconsin, General Polymers, PolyOne, Glenn Beall, and John Klees. Competent in resin characterization and analysis, his specialty is practical, hands-on injection molding training in plastics, rubber, LIM/LSR, metals, wax, ceramics, medical validations, and Infrared Thermography.

National recognition has come through ten patents, over 100 papers and industry articles covering plastics and processing. He has over 25 years on the seminar circuit and has several feature articles such as the "Productivity Challenge" and "Scientific Molding" In 2005, he was named as processor of the year by Modern Plastics. Many of these articles and papers can be found in the on-line archives of Plastics Technology and Injection Molding Magazine.

John teaches Scientific Molding (SIM) technology from the plastics point of view for design and processing with a passion that provides a significant emotional experience that you will remember. He presents practical techniques that improve your profits today while elevating your production to international standards. Let us keep plastic piece-part manufacturing strong. Manufacturing is critical to a nation’s growth. On-site seminars are a specialty, electric or hydraulic machines.
