Blow Mold Operator Training is a two-day course from PET bottle specialist Processing Technologies, Inc. (PTI). Designed for all skill levels, its goal is for attendees “to gain an understanding of the preform-to-bottle and machine relationships that affect the quality of bottles.” Areas of focus are machine operation, settings and process parameters for controlling and maintaining a stable process. Causes of defects will also be covered.


Specific topics include PET properties that affect blow molding; introduction to drying and preform injection molding; and two-stage blow molding. Training can be customized with optional training on preferential heating, heat-setting, etc., according to the specific equipment in your plant.


The class includes roughly 12-12 hr of classroom instruction, followed by practical lessons at a blow molding machine.


The next scheduled class is Aug. 20-21 at PTI in Holland, Ohio. Classes can also be scheduled at customer locations.


By the way, PTI also offers Injection Mold Operator Training, a two-day course focused on injection molding PET preforms.
