Maintaining the consistency of an injection molded part is a challenge that has faced the injecting molding industry for many years. That challenge has recently become easier following the launch of Barber-Colman’s MACO compact controller which now incorporates Intellimold Melt Pressure Control as a standard option in all of its variants. In addition a new slimmed down version of the MACO compact controller will be available shortly that can be retro fitted to any injection molding machine.
This patented method which was invented by Milko Gergov of MGV enterprises can genuinely be described as the "New Definition" of Closed Loop Process Control for the plastics industry. Per Mr. Gergov, "This control option gives the processing people the tools to mold plastics from materials point of view. The MACO compact controller in combination with your injection molding machine allows the production of parts to a more consistent quality. In addition cycle times are improved, energy costs are reduced and the operator has real time control over the molded part shot to shot. Ease of set-up will also be of interest to the operator.” Set-up is so straight forward you could describe the MACO compact controller with Intellimold as the cruise control of the injection molding business”.
Steve Schroeder, Global Business Development Manager for the Plastics industry at Eurotherm went on to say, “Operation is self compensating, there is no need for re-tuning or adjusting for processing variables that may arise as viscosities, temperatures and materials change. The novelty is in the fact that for first time the non linear behavior of the molten plastics is electrically "toggled" with the non linear behavior of the machine (screw velocity adjustments in real time) to achieve and maintain melt pressures specified by the material suppliers for optimum composition and morphology. Thus the maximum materials properties will be covering part performance specifications.” With Intellimold, process changes are made automatically while each part is being molded. This eliminates the frequent process changes needed to compensate for changes in the material, machine, and mold all of which take time and reduce production efficiency. Eurotherm claims that this type of processing has not been available as a standard feature on any machine or stand alone control system on the market until now.
