Fundamentals of Injection Molding
- Linking the Process and the Product - 

This course, titled "Fundamentals of Injection Molding - Linking the Process and the Product", consists of five (5) levels. An understanding of all levels is required in order to receive a Certificate of successful completion (if requested). The final test can be taken at any time. However, failure to pass the final  test will require that you re-register for all levels in order to take the test again. The agenda for each level is shown below. 

Fee = NOW FREE (limited time only).  Note: if you wish to obtain a Certificate for successful completion of any free seminar, we must charge a handling fee of $14.75 and it can only be mailed to an address within the continental United States.
