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 (for $14.75 - see below). The final test can be taken at any time. A passing grade of 70 is required to receive a Certificate. If a Certificate is desired, a failing grade requires a retake of the test until a passing grade is achieved. The agenda for each level is shown below.
Fee = FREE (members 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. Information is provided on the final test form.
