INTRODUCTION FOR PLASTIC INJECTION MOULD DESIGN – OPERATORS AND MH TRAINING
This course walks operators & material handlers through the proper techniques for material handling and troubleshooting. The course explains the ins and outs of raw material management, what to consider when choosing materials, what to watch out for in product labeling, and what to consider when determining dryer requirements. Emphasis will be on the main material considerations and how drying affects the process. The objective of this course is to reduce errors and inconsistencies in processing due to operations & material handling issues.
