"On average for jobs transferred into our shop we cut cycles by over 30%, some near 50%, using John's teachings."  - THA  Site Manager

"I took your course 20 years ago and it was the most useful investment I have ever made"  C.J.

I've attended several IM courses and yours are the most practical and useful."  - D.R., H Corp.  Processor

"This is the best bang for the buck class."  - M.R., GCP Corp .  Production Mgr

"If injection molding is your profession, Bozzelli's course is a must attend!"  - WK   Processor

"You are molding blind without this course."  -TG Engineer

Walking in thinking I knew a lot about molding...left knowing I had much to learn."   - BP  

"Impressive on all levels. The most informative class that I have attended to date.  Too much information for 3 days." - Michael H. 

"Like taking a drinking from a fire hose; fast paced and tremendously useful."  - Steven Hutchinson 

"Again, I thank you for your help and advice, and I know that the expansion of our molding operation has been made possible because of the implementation of the practices learned in your Scientific Injection Molding Seminar." - Ron Beaver 

"Your technique (Scientific Molding) also works on LSR (Liquid Silicone Molding). One of my customers had a 40% reject rate in an LSR application. After one hour, utilizing your technique I reduced the waste to under 5%."   - Anthony J. DiBattista, AC 

"It gets better the second time around." - Eddy Soto, Ki Industries 

"I've been molding parts for 13 years. This is the first time I have really understood what I am doing with the plastic. I would recommend this course for beginners to seasoned veterans, Engineers to Processors." - Joe Mitchell Bullard 

"...the Deming of our time" - Robert Shaw of K T & M Corp. 

"Best kept secret in the plastics industry!" - Mike Godlove

"Before this course, I felt comfortable with our processes. Although humbled, I can honestly say that I didn't know what the hell I was doing. It was a significant emotional experience!" - Doug Oberlander, Syndicate Sales Inc. 

"Bozzelli & Klees seminar was packed with so much relevant information, it couldn't possibly be absorbed during one visit. It was so much fun, they should open a resort - 'Molding Land." - John Robison, Supplier Quality Engineer 

"Without question the best advanced injection molding seminar I have had!" - Mike VanHout 

"The cost of this course will pay for itself 100 fold if the principles learned are implemented." - Bill Thornton MN 

"Since our last conversation we have optimized 3 tools that have been a pain in the tail since the beginning. After optimization (via Scientific Molding), we are averaging 30% cycle improvement and zero defects. One of the parts took 18 days a month to meet demand; now it only takes 9 days, a 55% improvement. We just identified the problems one at a time and corrected them."  - Richard T  Processor/Engineer

"I was at a point in my career where I was trying to dig deep and learn the science behind optimizing injection molding process parameters. I just happened to hear a talk by John at a local SPE conference and I immediately knew what I wanted to do for the rest of my career. John's passion for processing is contagious. If you have not been to a Bozzelli class or conference, GET TO ONE. You will not regret it. Thanks, John." - Brett L.  Engineer
