Injection Molding  and Plastics Industry Experts

•  Rodney Rotman, founder of 2R Automation, has experience with all of the Pro-Set control solutions offered by Allen-Bradley since 1986 and has been instrumental in working with Allen-Bradley and Bosch Rexroth to bring a new platform of controls to market.  Rodney began his career writing PLC ladder logic and programming various HMI platforms to meet the needs of the plastics industry and is still involved on the factory floor today servicing and upgrading existing systems and assisting OEM’s with new technology.  Rodney is an electrical engineer who likes to work on hydraulic and control systems. 

• 2R Automation specializes in controls and hydraulics.  Existing systems can be upgraded and improved to increase productivity and reduce scrap – both of which are necessary to remain competitive in today’s world wide economy.  Well designed hydraulic systems can be improved by upgrading controls and older machines can be upgraded by adding an injection valve along with upgrading controls.  These are two straightforward ways of utilizing existing machinery capital to increase productivity.

• Injection Molding and the plastics industry is 2R Automation’s specialty.  Our system utilizes the Bosch Rexroth DPQ controller for injection control which provides the best injection process control on the market today.  The repeatability of the injection profile is the reason that this controller outperforms any other.  The DPQ module allows for configuring up to five (5) segments of injection control, five (5) segments of pack control, and two (2) segments of backpressure control.  We also use the Bosch Rexroth DPC controller for the best clamp control on the market.  The clamp controller controls high mass clamp so well that the cycle time can usually be reduced because the clamp profiling can be done faster without causing jerky motion or abrupt stops.  Both of these Bosch Rexroth controllers communicate via DeviceNet so any Allen-Bradley controller can be used to sequence the injection molding machine.  2R Automation normally uses the CompactLogix (1769) line of controller (or any AB PLC) with a twelve (12) inch VersaView operator interface.  Our stand color configuration as shown on the injection profile above utilizes light blue for setpoints and red for actual values.  We start with our base screen set and adapt it to meet the configuration of the injection molding machine on which it is being installed.  Most controller upgrades can be accomplished in one to two weeks from start to finish.  2R Automation can provide a turn key upgrade or work with your maintenance or local contractor for installation.  2R Automation provides a completely documented ladder program, the runtime operator interface and a complete set of electrical and hydraulic prints upon completion of every project.  Please contact us for a quotation on your particular machine.

• 2R Automation can also provide custom programming, training, troubleshooting, robot interfaces, sequential valve gating systems, gas assist interfaces, and add on injection units for multi-shot capabilities.
