Seminar Overview: John Bozzelli, Scientific Molding Pioneer

Validating Medical Molding Processes and Parts

Process Optimization via Scientific Molding

3 Days
Abstract: This seminar concentrates on process optimization with hands-on, at-the-press instruction and defines the necessary variables to establish a “Universal Setup Sheet”. By the end of the course we will have established a setup sheet that can be used on any correct tonnage press that can accept the mold. Different barrel sizes, electric or hydraulic; the setup sheet will work on all. Having one setup sheet per mold rather than a separate setup sheet for each different press will not only improve consistency but also speed setups and bring back healthy profit margins.

LIMS/LSR Process Optimization via Scientific Molding

3 Days
Abstract:The course provides scientific molding technology and strategies specific to molding silicone thermoset resins. We will cover data based process optimization with at-the-press training to set up and properly document the process for FDA validation.  Learn to think like the silicone.  The process will be documented with a "Universal" set-up sheet.  This seminar focus is on developing a production capable process that will replicate identical parts on any appropriate machine, electric or hydraulic.  We document the necessary variables to establish a "Production Process". The resulting setup sheet will work for a given mold on any appropriate press.

Scientific Molding For Critical Tolerances

3-4 Days
Abstract: The course will provide the details for you to develop and document an optimized process that will make production.   You will leave with a documenting/validating procedure that will pass the most stringent medical or electronic  requirements. You will be able to run this process on another machine or site. At-the-press training. Learn plastic variables, not set points. Applies to all high-performance, critical tolerance injection molded parts. See plastic flow through glass window molds to visualize and prove the six important "Plastic" variables you need to control. 

Troubleshooting Common Injection Molding Part Problems

3 Days
Abstract: This covers a brief industry introduction of some basic processing guidelines and a hard hitting analysis with remedies of the industry's top 18 molding problems. The course is aimed at processors, but provides insight for customers, managers and designers. A tough 3 day seminar with a brief at-the-press session.

Scientific Molding Overview

1 Day
Abstract: An introduction to the strategy of molding from the plastics point of view. Machine variables vs. plastic variables are exposed as well as the basic core principles of this six-sigma strategy. One plant saved $200,000.00 after this 1 day course, a rare case but shows the potential. Supervisors, engineers, processors and corporate officers will benefit by obtaining a technical overview and getting everyone on the same page.

Coloring Plastic At The Press

2 Days
Abstract: Designed for optimizing, use, and blending of colorant at the press; that is, in-plant coloring of plastic resins. Discusses machine requirements, screw design for melt uniformity and mixing elements, blending color concentrates, evaluation of concentrates, and typical problems with practical proven resolutions.

Advanced Scientific Molding with John Klees

4 Days
Abstract: This rigorous four 8-hour day seminar, presented by John Klees (Seminar Leader) and John Bozzelli, is targeted towards process understanding, process development and process optimization. This seminar is a combination of John Klees’ “Injection Molding Technology” (Seminar I) and John Bozzelli‘s “Scientific Molding for Critical Tolerances” with tooling tips from John Klees. This seminar is specifically designed for people who start up a new mold or people who must optimize existing cycles, as well as personnel responsible and accountable for quality-molded product molded at a competitive cost. On-Machine demonstrations supplement the classroom material, so you will be involved with actual machine operation. Relationship between hydraulic pressure, plastic pressure, cavity pressure and on-machine rheology is demonstrated so that you may mold on hydraulic or electric presses to obtain identical parts. Emphasis is placed on practical setup procedures, which will optimize your overall molding cycle.
