RJG, Traverse City, Michigan, is a full-service injection molding solutions company that offers customized end-to-end solutions, has announced its Math for Molders eLearning course now is more convenient than ever, allowing students to complete each module at their own pace, including the replaying of sections they may struggle with and takes an average of nine to 10 hours to complete (A total of 12 months from the day a confirmation letter is received.).
Math for Molders provides foundational math skills practice to prepare molders for process development, troubleshooting and machine testing that are involved in more advanced RJG courses. There are eight units in the course with multiple interactive modules in each that include videos, animations and practice activities. Utilizing real scenarios, molders will be more prepared to calculate data, enabling them to match mold requirements with appropriate machines and avoid common defects while preventing mold and machine damage.
Course highlights:
- Area: calculate area of various shapes (squares, rectangles, triangles, circles and irregular shapes) and calculate total projected area at the parting line
- Ratios: calculate ratios used in screw design (compression ratio and L/D ratio) and intensification ratios for hydraulic machines
- Volume: calculate volumetric shot size and barrel capacity using a volume formula triangle
- Percent usage: calculate percent usage of barrel capacity, cushion and maximum injection pressure
- Distance, Speed and Time: calculate linear stroke, and calculate actual fill and speed using a distance, speed and time formula triangle
- Averages: calculate average cavity pressure, platen deflection and part weight
- Percent Change and Percent Variation: calculate percent change of part weights and of actual and expected fill times and calculate percent variation of multiple parts in a multi-cavity mold
- Force, Pressure and Area: calculate maximum available clamp force and minimum required clamp force using a force, pressure and area triangle
