eDART System™
The eDART System™ is the most powerful process control system on the market today. With flexibility and ease of use at the core of its design, the eDART System™ has been built by molders for molders. This diagram shows the components of a typical eDART System™. Many configuration options are available.

RJG offers free eDART training for those who have purchased or may be considering the purchase of an eDART. For more information contact the RJG training coordinators.


eDART™ Process Controller
eDART’s retain process and set-up data for every mold run on their designated machine. Sensor configurations, process templates, alarm settings, and other setup information are automatically stored and can be easily shared with other eDART’s through a distributed network architecture. This unique ability to “share” information between eDART’s makes them interchangeable.

eDART flx™ - Automated Part Containment (APC) at 45% Less Cost
What is not to like about RJG's new eDART flx? It offers a significant cost savings over other systems as well as being 45% less than the full functioning eDART. Because It has been tailored specifically for automated part containment many of the advanced features of the original eDART aren’t needed, which makes the eDART flx simpler to use and considerably more affordable.

RJG has decades of process monitoring and control experience in the injection molding industry. All of that experience has been integrated into the new eDART flx. In today's competitive market, shipping even one bad part to a customer can cause a molder to lose business. This makes it more important than ever to invest in a system to guarantee quality to the customer. eDART flx provides a simple to use, failsafe solution for sorting parts. The system can be set up to do three way sorting, segregating good, bad and suspect parts. Good parts can ship to the customer, rejects will be scrapped and suspect parts can be isolated and sorted at a later time to determine their quality.

eDART flx is the easiest to use system in the industry. Considering the proven software, ease of set-up, robustness and affordable price there isn't a more powerful tool to ensure that no bad parts ship to your customer. And best of all both RJG's expertise and world class customer support are still inside.

Lynx™ Digital Devices
Lynx™ devices feed data to the eDARTs™ through digital communication, allowing for easy ‘connect and go’ usability. Job set-up information only needs to be input the first time a sensor is connected, dramatically reducing setup times. The next time the sensors are connected, the system automatically recognizes their digital ID and calls up the job associated with that device or sensor. Lynx™ sensors also carry critical calibration information and self-checking diagnostics capabilities. Some of the common devices are listed below and many others are available.

Sequence Input Module: Once wired to the molding machine, this module provides the system with machine timing sequences including injection forward, screw run, mold closed, first stage and mold opening.

Dual Relay Output Module: For machines and automation equipment that accept digital signals, this device provides a normally open or normally closed contact for process control or 3-way part sorting.

Analog Input Module: Analog sensors or equipment can be integrated with the eDART System™. This module accepts a 0-10 VDC signal from these devices and communicates it to the eDART™.

Stroke/Velocity Sensor: Tracking injection velocity, shot volume, cushion, and plasticizing rates is as simple as connecting a Stroke/Velocity sensor. The stroke/velocity sensor is available in various cable lengths for use on varying machine sizes.

Lynx Quad Temp Thermocouple Sensors: Connecting these sensors with new and existing thermocouples provides you with insight into the key process variables. Thermocouple sensors give you the ability to track barrel zone, mold, and mold coolant temperatures.

Lynx™ Hydraulic Sensor: The eDART™ calculates injection pressure and plots it along with other profiles. These curves provide many machine and process variables, displaying hydraulic consistency and repeatability over time.

Lynx™ Cavity Pressure Sensors: Implementing cavity pressure has never been simpler than with digital cavity pressure sensors. Sensors are automatically recognized by the eDART™ and identify themselves along with the mold being run.

The LS-DP-100 Lynx Delta Pressure Sensor: The sensor measures the difference in coolant pressure between the mold inlet and outlet and is designed to be used with the eDART System™.. This provides information about the cooling capability and consistency supplied to the molded part.

Lynx Surface Mount Modules: These can be mounted inside or outside the molding machine or on or within auxiliary equipment. The Analog Input Module interfaces with temperature, dew point, pressure and other remote sensors. The Dual Relay Output Module supplies signals to part diverters, valve gate controllers, machine input cards and other applications.

Sensor Adapters: These sensor adapters allow standard piezoelectric and strain gauge sensors to be connected to the eDART™.

eDART™ Software
The flexibility of the eDART System™ is demonstrated in the eDART™ software. The software included in the eDART System™ is designed to ensure quality parts shot after shot by allowing the user to see and adjust process conditions in real-time, and provides password protected areas to limit access to vital settings. With its layered, modular technology the eDART System™ can be customized for every company, facility and machine. While many tools are available, the most common are described below.

Process Analysis and Control Software

The Process Analysis portion of the eDART™ software provides tools that help the user view the process in real-time, analyze the information and determine what actions that need to be taken.

Process Match Meter – Designed for practical use on the shop floor, the Process Match Meter has easy-to-read gauges that clearly indicate whether or not the process is stable.

Cycle Values, Graphs and Templates – Once an optimal process is achieved, the data collected can be used to create a template of the process parameters. Matching this template ensures consistent part production. Real-time analysis for both process and machine allows users to view the current injection pressure, machine variation, injection volume, variations in material viscosity, and much more.

Summary Graph and Statistics – At a glance, see how well the process stays within set limits. User selected variables are plotted and statistical calculations made for analyzing process capability and consistency to provide a representation of process capability over time.

Alarm Settings – For automated part containment, molders can set alarm levels around specific summary values. Based on these alarm settings, the part diverter control relays a good/bad signal to a robot, diverter or conveyor.

V P Transfer Control – This process allows implementation of DECOUPLED MOLDINGSM techniques by transferring the machine from velocity to pressure control on cavity pressure, hydraulic pressure, position or time.

Optional Software Tools

The optional software tools for expanded process analysis and control are more examples of the flexibility and depth that is possible with the eDART System™. To anticipate the needs of progressive molders, RJG has developed the following software tools to meet the demands and advances in molding technology:

Shuttle Control – Be able to differentiate between positions, collect and organize data on the current mold half in certain shuttle or rotary molding applications.

Basic 3-Stage Control – With a relatively simple upgrade, the capability of older machines can be significantly improved. The addition of a load compensation valve enables older relief-valve machines to do 2 or 3-Stage DECOUPLED MOLDINGSM where fill, pack and hold are repeated shot after shot. This software tool allows the user to input individual set-points for transfer, making the process more capable and less susceptible to flash, overpacking and mold damage.

Valve Gate Sequencing – The key to a robust system, valve gate sequencing allows precise, individual control of flow fronts in the cavity. This precise control maximizes uptime, process capability, and performance. This is especially true on large machines with complex processes using hot runner valve gates. Types of Valve Gate applications include: Independent Valve Gate Control, Sequential Valve Gate Control and Alternate Cavity Valve Gate Control.

RJG Insight System® Server
Users can access RJG systems without the worries of additional network load, unwanted broadcasts, or uncontrolled traffic by adding the RJG Insight Server to the system. The server is designed to separate the network traffic of the eDART™ system from your existing network by acting as a bridge between the two networks. For ease of operation and security of data, the addition of the server not only eliminates network traffic jams, but provides constant backup, data storage and secure customer support access.
