Plastic411 Set Up Training

Plastic Injection Mold Set Up

Garrett MacKenzie: On-Site Trainer
This class is designed for new to intermediate plastic injection Set Up teams that will be regularly setting up presses and making adjustments on the production floor. It is also a great venue for managers/supervisors that are new to molding and need a better understanding of how the molding process works to better perform their oversight of employees. Unlike many other training programs, this training takes place on your production floor using YOUR presses, materials, equipment and processes. This helps to assure that training is plant specific, which increases the impact of the skill sets taught within your organization.
