Machine Maintenance Workshop
Ensure your machine reaches your expected performance!
This three-day course is designed for machine maintenance personnel responsible for upkeep, troubleshooting, and preventive maintenance of injection molding machines and ancillary equipment. It is common in the industry that maintenance personnel are not trained to recognize how machine performance affects final part quality. The performance of the press is critical to a molder’s ability to deliver consistent parts. Maintenance personnel must understand how to identify and fix press performance concerns in order to optimize press tuning.
- Screw and barrel measurement and documentation
- Screw and barrel wear evaluation
- Platen parallelism
- Hydraulic systems: closed and open loop systems, variable displacement pumps, and proportional valves
- Electric machines: servo and frequency drives
- Testing for proper material dryer operation
- Proper sizing of plant cooling system
Upon completion of this course, personnel should be able to conduct and evaluate the test procedures in the above. In addition to the tests performed the knowledge gained in the class will assist the student in finding root cause for poor machine performance.
Participants will be able to effectively communicate with production personnel in regards to machine maintenance issues and their impact on process repeatability and part quality.
Maintenance personnel will be able to evaluate machine capability in the following areas:
- Load sensitivity
- Velocity linearity,
- Dynamic check ring repeatability
- Static barrel and check ring repeatability
- Hydraulic pressure response
- Pressure linearity.
Course Length: 3 days
Public Classes – No prerequisite
In-Plant Classes – A functioning eDART System running Version 9 software must be available for use during the class. (Arrangements can be made for RJG to provide an eDART, but this must be prearranged with the trainer in advance)
