Data Collection & PID Control:

Programmable PID controlled Resin Temperature – The resin temperature required for injection will be programmable in the system configuration screen. This value will then need to be met for the system to being the injection, ensuring the resin at the mixhead it at the prescribed temperature for injection. Upon initiating the injection start, the machine will remain in a recirculation mode until the resin at the mixhead is at the proper temperature, once confirmed to be at the correct temperature the machine will switch both the catalyst and resin valves automatically to the inject position and complete the automatic injection process. Preset temperatures can be programmed for both the recirculation temperature and the Injection temperature separately. In-line heater is a 2000 watt 240 volts heater with solid state relay controls for long-term life.  
                       

Process Data Collection System – Each of the primary process concerns including: part identification, time of injection, resin / catalyst ratio, resin temperature (with heater option) resin injection pressure, rate of injection, part sequential number. Dwell time per injection cycles, total resin used on an inventory usage for all moldings, all are stored on a Dell Laptop PC. This then allows for collected data to be organized into Excel spreadsheets for easy data review.  The Dell Laptop PC allows for the data collected to be communicated through a 10/100 Ethernet port or Wireless network for integration with an in-house communication network system allowing for all of the data to be viewed by selected persons directly on their personal office desktop computers. This feature offers unprecedented ease for the Process Technician as well as Production & Equipment Maintenance Management  

Below are Example Screen Shots of the Primary Data Collection System Pages, all of which are in a Excel Spreadsheet format for easy data storage and comparisons:

PDCS Page:

The above page is the PDCS page which is the page in which all of the raw data is collected. The red and green blocks show the condition of each of the PLC I/O conditions. The precise pressure, temperature, flow rates, catalyst ratio, etc. are captured on this page at a rate of 1 sample per second.

Daily Production Log Page:

The above page is a unique feature of the Infuser PRG system. Found on the display of the Infuser PRG under the Supervisor configuration are the records for each of the primary maintenance details, showing the amount of resin that the machine has pumped since the last time each detail was serviced. This has proven to give the Maintenance team the needed information of the actual machine usage which has taken place, without this feature the best guide the Maintenance staff has to work with is the calendar which truly has no correlation with actual machine usage, the Infuser PRG has a “built-in Odometer” in a sense for each of the critical maintenance details. With the data collection system this information is collected and can be sent directly to the Maintenance Supervisor’s desk for daily review and preventative maintenance scheduling. Without the data collection system, the maintenance supervisor has access to this information, yet he must go to the Infuser PRG machine, log-in, and review the details, with the data collection system this information is only a mouse click away on his desk

Process Variables Page:

The above page represents an example of the Process Variables which are critical to the process technical engineer in either troubleshooting the production process or to refine the performance of the process. Here all of the individual process variables are recorded for immediate and long-term review. One of the common uses of this information is for history review of the molding process, this is especially important when the production group reports a problem yet do not recognize just what has changed, here the precise information of how the same part was molding one month or many years ago can be reviewed with just a couple mouse clicks, also since the information is stored in Excel spreadsheets the data can be combined and reviewed from many different molding events if needed. This record eliminates the history being held in the memory of the various operators over the years, with greater accuracy and reliability as well.

In-line Coriolis Mass Flow Meter -  For true ultimate process control and verification the In-line Coriolis Mass Flow Meter sets the standard for excellence. The Coriolis meter will indicate the actual flow rate and totalized flow of the resin a mass basis. This eliminates the inherent variance present in any piston or gear meter mix machine. Further the Coriolis meter will provide real-time readout of the resin mix Specific Gravity which will confirm the filler loading content. This is an invaluable indicator of the true process control needed into today’s RTM molding operation.

Mixhead enclosure frame & Remote Control -  The mixhead will be surrounded in a ½” square box steel tubing protective cage enclosure with remote injection controls. System “start”, “Stop”, Flush” and E- Stop” can be controlled from the remote start located in the enclosure frame.

RS485 Network – The Infuser PRG can be upgraded to a RS485 communication network system, this allows for nearly countless modules for input and digital output control. The typical user of the RS485 network feature is one who has many different molds each with different Thermocouples and Pressure / Vacuum sensor which are monitored not only at the time of injection, they are continued to be monitored after the injection. This allows for the Infuser PRG to be controlling a separate molding cycle completely independent from the other mold(s). Other uses is to network other operations with the Injection process, typical application is to use the RFID Tag reader on the initial Gel-coat process to initiate the time a mold begins the molding process, then to track the mold as it passes through the processes until the part is demolded. Through the network and the use of the RFID system, each mold and subsequent molding can be fully tracked as it passes through the production molding process. The part once demolded, can then continue to be monitored using printed bar code or even additional RFID tag mounted to the part through its travel.

EQUIPMENT WARRANTY

1.) All products manufactured by JHM Technologies, Inc. are warranted under normal usage and service against defects in workmanship or materials for a period of 6 months from the date of shipment. JHM Technologies, Inc. will repair or replace at its option any product or assembled components it finds to be defective.
