Part Quality Control for Users of Plastic Parts
On June 10th RJG is offering a new technology day that is geared for the users of plastic parts and how they can work with their suppliers to control quality issues.

What's New in the Lab
Maruka has consigned a new Toyo 55 ton molding machine to our training lab. Additionally, Novatec consigned a dual bed desiccant dryer.

New Sensor Selection Chart
Click here to see our new sensor selection chart to help you determine which cavity pressure sensors would work for your application. Keep in mind that our customer support department is always available to work with you on choosing the best sensor for your needs.

Additional Sourcing for Lynx Cables
RJG will now use an additional supplier for our Lynx Digital cables. In addition to our Lumberg cables we will now carry Phoenix Contact cables. With the exception of a color difference near the connector, both brand cables are the same.

FREE On-Line Assessment Testing
A good first step in deciding where to start with training is for you or your staff to take our on-line Assessment Test. We will then help to determine the best training strategy for you and your organization. If a company plans to test more than 4 individuals, please contact the RJG training department to arrange for company-wide scoring.

RJG Knowledge Base
Sign up to gain access to Art Schubert's eDART Tips. Art is RJG's lead development engineer and has been responsible for many of the innovations created at RJG. Art will be monitoring the Knowledge Base and answering your posted questions. Users will also be notified of future "Art's Tips" by email.

Sensor Solid Model Database
Customers can now import our sensors in a 3-D solid model for their tool design software. Simply select the desired model number and use the contents of the downloadable .zip file to add the sensors to your tool model. The .zip file also contains information for installation and tooling instructions.

RJG Articles Online
RJG has written numerous articles for plastics industry magazines. These articles can now be viewed by browsing to the Tech Resources page of the RJG web site or by clicking this direct link.

Download eDART Software 8.5
RJG's eDART customers can download the latest software updates directly from our web site. If you have any questions contact Customer Support.

Newsletter Content Recommendations
Let us know if there is anything specific that you would like to see in upcoming newsletters.

RJG is looking for Customer Input
A main initiative at RJG this year is to work with our customers to get 95% of the eDARTs in the field fully implemented. RJG is looking for comments or suggestions as to how we can improve our equipment or the process of implementing our equipment. We'd love to hear from you.

Poll of the Month
Every month we will post a new question regarding our products or services.

RJG is restructuring its website to serve you better. Please help direct the future website by responding to this question: Please click here and scroll down to answer!


eDART Data Manager Released for Beta
RJG's new eDART Data Manager (EDM) has now been released for Beta testing at several customer locations. The EDM is a hardware and software solution for managing all of your eDARTs, monitoring the jobs they are running, and viewing their processes in real time. With features such as the Advanced System Overview, Cross Copy, automated data backup, and much more, the EDM makes it much easier for you to manage your eDARTs and the data they contain. The eDART Data Manager is scheduled for full release on June 15th. Click here for more information about the EDM.

The ID7-Tester is used to test the ID7-D-SEQ Module for proper wiring without the module having to be hooked up to an eDART.Click here for more information or contact us at 231-947-3111.

Extended Direct Sensor Approach
RJG’s Extended Direct sensor is a new approach to direct sensing of mold pressure, which is ideal when limitations make it difficult or impossible to use traditional direct sensors. This approach simply uses a pin to transfer the force from the cavity onto a button style sensor located in the clamp plate. Some of the limitations that molders face with direct sensors include:

  • Access to the sensor for recalibration is difficult
  • Detection of defective sensor or a pre-load is difficult
  • Exposing sensing wires to damage when the mold is serviced
  • Small mold cavities aren’t able to accommodate direct sensor
  • Sensors that will likely require cleaning because of the material type
  • Higher temperature near the cavity than the direct sensor specification
  • Exceeding the limits of a direct sensor when contouring the end

The  "Extended Direct" approach can be implemented by using a non-ejecting pin of an identical diameter to one of the standard direct sensors. The installation is similar as that used for non-ejecting pins but with some important differences:

  1. The machining of the area near the cavity employs the same dimensions on the diameter and land as for the equivalent sized direct installation.
  2. The pin is equipped with an O-ring and groove that is identical to the direct sensor and is the same nominal distance from the cavity wall.
  3. The pin is initially cut slightly longer than required and tuned to the correct length to obtain an installation flush with the cavity wall after the initial tryout.

Puck Sensor
RJG is developing a fundamentally new approach to instrumenting large molds such as those used in the automotive and large appliance industries. This new cavity pressure sensor is called the Puck sensor because it resembles a hockey puck in size and shape and is used in conjunction with RJG's transfer pin and extended direct sensing techniques to allow sensors to be placed on the outside of the clamp plate. A key advantage is the ability to access the sensors without disassembling the mold. Large molds often have to be returned to the mold maker's shop for disassembly, which means downtime and labor costs far in excess of the cost of the sensor. The new Puck sensor approach allows for service and removal for calibration checks, even while the mold is in the press. If you are interested in beta testing this new product, please contact Michael Burrows at 231-933-8139.

No Tooling Department Should
be Without One!

Released in 2007, the easy-to-use Lynx Sensor Tester has been incredibly popular! The tester informs users if a sensor is functioning correctly. The Sensor Tester can be attached directly to the sensor using a standard cable. Within seconds the user will know whether the sensor is within spec. The benefits include: the ability to check sensors while tools are assembled in order to catch mistakes early when they can be corrected cheaply, the prevention of tooling-damaged sensors being discovered on the shop floor, and elimination of down time.
