A Math Course Designed Specifically for Molders

Molders need to use math in their daily jobs, whether they are calculating shot size, transferring a process from one machine to another, or trying to determine clamp tonnage or material utilization.

When most of us learned math in school, we weren’t given real-life examples that related to the job that we are doing today. And as with most things, if you don’t use it…you lose it.

AIM’s Molding Math course was designed to teach you the concepts you need for your job using realistic examples that are found daily in a molding shop. This course can be taken by itself, or serve as a refresher before you jump into one of our Molders’ Series courses or the PTE Program.

What makes Molding Math different?

AIM’s Molding Math course was developed based on needs identified in our Molding 2 Enrollment Evaluation.

On average, the molders taking this evaluation were scoring at a 34%, which was creating challenges for students in our Molders’ Series courses.

This course approaches math from a practical standpoint and is designed to give students an overview of various principles and applications directly related to the injection molding industry, including but not limited to:

  • Machine utilization
  • Hopper capacity
  • Shot volumes
  • Shot weights
  • Injection pressures
  • Intensification ratio
  • Clamp tonnage, and numerous other areas of application.

Students will be assigned homework each day and are provided an answer key so they can check their work. In addition, AIM will provide a detailed worksheet (upon an individual student’s request) that outlines the steps required to solve each homework problem.


How long is the course?

The course is taught over two consecutive days:

Day 1 = 4 hrs (1-5pm EST) with homework for day 1 assigned at the end.

Day 2 = homework review hour from 12:00-1:00 (optional per student needs); second half of the course is from 1-5pm, with homework for day 2 assigned at the end.


How much is it?

$795 includes all course materials, homework worksheets, and access to instructors for real-time support.
