Webinar: Minimizing Rejects and Part Variation with DECOUPLED MOLDINGSM Process Control Strategies

The most successful injection molders today ship only the highest quality, defect free parts, on time, and at the lowest cost, while minimizing the number of reject parts produced.  Understanding the root causes of variation that causes quality to suffer is paramount to establishing an optimum processing strategy.

During this webinar we will:

  • Discuss the root causes of pressure variations that cause many different defects, and how the molding system acts as an Amplifier of process variation.
  • Learn how to quantify the pressure variations in the molding system and monitor them over time.
  • Review the different DECOUPLED MOLDINGSM classifications and understand how they can be implemented to minimize the effect of normal process variations.
  • Know what molding machine capabilities are important for successful implementation of the different DECOUPLED MOLDINGSM strategies and how to test for these capabilities.

An Eye Opener...

"RJG came in to do an eDART demonstration on one of our machines. We had cavity pressure sensors in the mold so they set it up to monitor the conditions overnight. At the time we were doing 100% visual inspection. The next day the RJG sales guy took a quick look at the data the eDART had collected and informed us that we had made 4 short shots during the night. When we questioned our inspectors they claimed that no bad parts had been made and all parts were boxed up and ready to be shipped to our customer. I said that there must be a glitch with the system and refused to reinspect the parts. Not long after I received a call from that customer complaining about some bad parts he received. He followed it up with an email that included a photograph of 4 short shots that came in from that shipment. We all agreed that it wasn't a coincidence.

RJG Partners with the
University of Wisconsin Stout
RJG has partnered with University of Wisconsin Stout as a location to hold public training events in the Upper Midwest. UW Stout and RJG were introduced through Phillips Plastics Corporation and we have continued to further develop our relationship. Students can take advantage of the equipment that RJG will be putting in their lab. Also the University has offered to host some public seminars for RJG. This relationship has some great benefits for both parties involved.

RJG and UW Stout have hosted one RJG public seminar event to date which was very successful. We are currently working together to bring more training to the university in an effort to offer more regionally located classes. We are just starting to place equipment in their lab and this will be up and running in very short order.

RJG would like to thank Phillips Plastics Corporation for the introduction to this partnership. We would also like to thank the university for being a great partner and we look forward to working together.

New addition at RJG SEA
RJG's office in Singapore is pleased to announce the addition of Kevin Zou to it's staff.  Kevin lives in Chengdu, China, and will be working to support our customers in the China market.  Kevin will be participating in RJG's Master Molder I and Master Molder II courses this coming summer, and we expect him to be a certified trainer by year end.  Kevin has past experience with eDART System networking and cavity pressure sensor technology, and we are happy to have him on board.

Can you tell if you’re running the right set-ups across your plant at a moment's notice? What about an hour ago? How about last night?

RJG's Process Stability Dashboard



RJG has assembled a suite of tools to manage set-ups for all molds that run in your plant, whether they have in-cavity sensors or not. Often, processes are not set up as documented, or they get changed after setup. If you have molds without cavity pressure monitoring you may not be able to see these changes occurring and the consequent effect on quality.

Since it's difficult and time consuming to find or manage these variables by walking around the plant, an overview is provided on the eDART™ network that shows each machine's status and how much it has deviated from the process it should be running. A quick scan down the overview screen will let you know any processes that are not being run as they should be.

Easily Interface to Multiple piezoelectric sensors
Soon to be released! RJG's Multi-Channel Piezoelectric Interface Connector with Mold ID allows users to interface up to eight RJG piezoelectric sensors while maintaining a small mold footprint. The unique cable connecting system allows for easy field replacement of cables and sensors with minimum nuisance and expense. The interface identifies the sensors and the mold to the eDART System™, so you can be sure you have the right mold running and the correct sensors selected. This product is building on the release of the Lynx Piezo Adapter for Fischer Connectors (see below left).

This product is currently being beta tested. Contact us if you would like more information.

Visually Balance Hot Runner Manifolds
RJG’s new Balance Viewer software provides a tool for users to visually balance hot runner manifolds. With an eDART™ process controller and pressure or temperature sensors in every cavity of a mold, you can use the data to balance the tip temperatures. Selection buttons on the software allow you to check the balance of other parts of the process: filling and packing, pressurization and mold temperature. The viewer tool automatically sets up and scales the bars for the number and range of sensors found. Once a tool is balanced, any odd behavior such as material build-up or clogging can initiate a warning system and will not be masked by automatic control adjustments. Click here for a demonstration.

Training Spotlight

Combination Systematic Molding - Workshop
June 22-25 Williamsport, PA
The intention of this version of Systematic Molding is to be a sort of "mini Master Molder I" where students develop a good level of confidence and ability at actually doing DECOUPLED MOLDINGSM on the job but not quite at the advanced proficiency level of MMI. This course will have around 16 hours of hands-on practice. It is especially good for companies who cannot afford the time or money to send their process techs to two weeks of Master Molder I training, but they need their people to have a certain level of proficiency with Decoupled II style molding. Click on the date above for details on this course.

Systematic Molding via LIVE eClassroom!
June 28 - July 2 (4 hours per day) - Online
This is an introduction course for anyone who wants to develop a systematic approach to molding at their facility. Students leave this course with a better understanding of how to develop a machine independent process, how to make data driven improvements to existing processes, as well as how to effectively trouble-shoot using scientific and systematic approaches. Students will also understand the cause and effect relationships between the machine, process, mold, and material as well as how and why polymer behavior is influenced. This will allow them to make informed decisions for lasting solutions instead of “band-aid” fixes to the process.This course is delivered directly to you via the internet with a Live instructor. You can “raise your virtual hand” to ask questions, see demonstrations, and re-watch the presentation later.

eDART Custom Inplant Workshops
These inplant workshops are designed for RJG eDART System users to further their understanding of the system's capabilities to help increase the efficiency of their molding operations. The training combines classroom time as well as a strong focus on taking what is learned in the classroom and going out to the production floor and applying the knowledge in order to drive Return on Investment (ROI) for the company. These classes are put together in a modular approach to help solve your unique needs and requirements for the training event.

  • Available for the eDART conx, flx, and apex. Some areas of focus are: stabilization, part containment, and advanced control techniques
  • Recommended for users after the initial system application training has been completed at the facility
  • Available in 1, 2, or 3 day formats
  • Unique combination of processing and data collection techniques to drive molding improvement and ROI in the areas you are looking for
  • Customized to focus and meet your needs
