And here is one from Jaime Marrero, Aftermarket and Sales Manager at Graham Engineering Corporation:
“I recently, while at the Packex in Las Vegas, had opportunity to read your new book uninterrupted during my flights. I found the information extremely helpful allowing me to begin connecting “the dots” if you will of the blow molding machines used in industry.

While I am not new to plastics or sales I am relatively new to extrusion blow molding, your descriptions and detailed explanations were excellent. As a result, I am finally grasping more of the nuance in the art of blow molding from your book.”
