The Injection Molding Processing development course is designed to provide an in-depth understanding of the injection molding process, including AIM’s unique approach to scientific molding process development and troubleshooting methods utilizing Flow Groups.
- Lab demonstration: AIM’s process development strategies
- Machine clamping systems
- Types of injection unit
- Understanding intensification ratio
- Plastic material’s influence on process development
- Material drying and measurement of moisture
- Measuring melt temperature
- Plastic variables vs. machine variables
- First & second stage process development methods
- Methods for identifying ideal fill times
- Variables in clamp tonnage estimations
- Use of simulation in process development
- Determining a safe start-up shot size
- Impact of shot size on the molding process
- In-mold pressure loss study
- Mold cooling strategies
- Using Flow Groups to troubleshoot variations
The course begins by discussing various mold bench tests that can help eliminate wasted time during the process development phase. The course then progresses into cooling and material drying strategies while discussing the impact each has on the molding process and part performance based on the material being molded. Next the course dives deep into scientific molding methods for both first stage and second stage while questioning the science and results of some of those methods. As a result, AIM’s adaptive molding process development strategies are presented as a next step in process development. These research and strategies are presented in-class and through an instructor-led demonstration in our injection molding lab. Finally, the course teaches a unique method for troubleshooting variations in part quality through Flow Grouping as a way reduce the time spent on mold debug and qualification.
