Plastics
These are examples of training that can be customized to meet your training needs. We will meet with you to discuss your specific needs and develop the training to meet these needs. The course length will depend on your particular needs. We can also combine parts of course descriptions of Injection Molding I and II or parts of Molding II and III to design a class to meet their needs.We have been offering employers the following 30 hour classes:
- Injection Molding -Setup and Operations
- Processing Technology and Troubleshooting
- Process Optimization
These are to give you a starting point to pick and chose the training that you want. Let us help you design the class to meet your needs!
