Master Molder® II

Course Description

Advanced techniques for daily processing strategies.

The Master Molder® II certificate course is designed for those who want to use cavity pressure data to monitor (detect and contain suspect parts) and to control velocity to pressure (V→P) transfer to minimize the effects of normal viscosity changes.

Using multiple development and optimization studies at the press, participants make data driven decisions to build robust processes using both DECOUPLED MOLDING II and III strategies that consider the capabilities and limitations of multiple target machines where a mold may need to be scheduled for production. Participants will document processes using Machine Independent Variables and utilize cycle graph templates to transfer processes to other capable machines more efficiently.

Participants will get extensive hands-on practice with the RJG CoPilot® System and examine historical summary and cycle graph data utilizing The Hub® to identify and correct process changes.* 

*At participating facilities only. If CoPilot or The Hub are unavailable, participants will utilize RJG’s eDART® System.

Course length: 2 weeks

Course Highlights
  • Develop and optimize processes using DECOUPLED MOLDING II and III strategies and cavity pressure data
  • Improve process repeatability with DECOUPLED MOLDING III process control techniques
  • Efficiently transfer and match process templates on different presses, focusing on what the plastic experiences in the cavity
  • Interpret graphs to troubleshoot and correct processing changes
  • Set alarms to catch short shots
Course Objectives
  1. Evaluate the processing capability of different types and sizes of molding machines to aid in appropriately matching a mold with a capable machine
  2. Identify the advantages and requirements of using a DECOUPLED MOLDING III processing strategy
  3. Develop and optimize DECOUPLED MOLDING II and III processes using data acquisition devices (CoPilot) along with machine and in-mold sensors
  4. Document robust DECOUPLED MOLDING II and III processes on a Universal Setup Sheet using Machine Independent Variables
  5. Efficiently transfer mold processes and match processes on different types and sizes of molding machines using universal setup sheet data and CoPilot cycle graph templates
  6. Compare alarms setting strategies and practice setting alarms to catch short shots
  7. Analyze cycle graph and summary graph data to identify process changes and troubleshoot process issues
  8. Identify various sensor types available for various instrumentation projects and select an appropriate cavity pressure sensor location and size
Course Prerequisites

Required:
To register for the Master Molder II class, it is required that you have received your Master Molder I certificate.

Course Recommendations

To maximize the likelihood of successfully completing the timed assessments that are required for earning a certificate, RJG strongly recommends a minimum of 3 months between the Master Molder I and Master Molder II courses to allow participants time to implement process development skills learned in Master Molder I.

For those less familiar with setup and use of the RJG CoPilot® System, advance completion of the on-demand, self-paced Meet Your Copilot course is recommended, but not required.

Availability 

This course is available publicly.
