Welcome to RJG®, Inc. eLearning!

**This course is now accessible using mobile devices such as smart-phones and tablets.** The Math for Molders course is intended for anyone who struggles with mastering the math skills needed to successfully complete injection molding processing courses. Students will better grasp the math techniques taught, and the knowledge provides a better math skills foundation for future RJG courses. Course Highlights: - Calculating area for various shapes to understand square inches at the parting line - Clamp tonnage requirements to understand using square inches with plastic pressure to establish clamp force requirements - Ratios to calculate intensification ratio, screw design - Using a formula triangle to understand how force, pressure, and area affect the process - Speed versus time to verify the machine is capable of delivering the plastic to the mold - Activities for solving real mathematics problems with the molding process Read more

The Area module of RJG's Math for Molders course includes lessons on how to use specific mathematic formulas to calculate the area of the most common shapes (squares and rectangles, triangles, circles) as well as irregular shapes and total projected area. The lessons feature practical examples related to plastic injection molding, opportunities for practice, and an assessment. Read more

The Averages section of RJG's Math for Molders course focuses on how to calculate averages that help molders understand what is typical in a process, and possibly lead to making well-informed adjustments that lead to consistent, quality parts. The lessons feature practical examples related to plastic injection molding, opportunities for practice, and an assessment. Read more

The Distance, Speed, & Time section of RJG's Math for Molders course uses a formula triangle to calculate these critical values that are often used to determine machine performance and maintain part quality. The lessons feature practical examples related to plastic injection molding, opportunities for practice, and an assessment. Read more
