Injection molding monitoring system

Advantages of introduction

Multilateral analysis in which multiple pieces of information are integrated

Information including in-mold pressure, in-mold resin temperature, and mold surface temperature, as well as information on measurement instruments and injection molding machines from other manufacturers is imported as analog voltages and displayed with the time axis synchronized to achieve more advanced analysis. The displayed waveform allows alarm signals in the set monitoring frame to be output and the measurement data to be recorded, making it possible to use the product for mass-production monitoring.

  • Simultaneous monitoring at up to 24 points

    By connecting three pieces of MVS08, it is possible to measure information including “in-mold pressure,” “in-mold resin temperature,” and “mold surface temperature” at up to 24 points in real time. The product can solve the challenges you face concerning multi-point measurement such as installation of various sensors in cavities of multi-piece mold.

    Standalone function that is useful in mass production

    Even in a standalone condition in which connection to a PC is not made, the product can output alarms and record measurement data. As it is possible to select a set of measurement conditions from 10 measurement condition sets stored inside, it is not necessary to connect to a PC to change the measurement conditions. Connecting a USB memory stick to the body of this product makes all data automatically saved. Therefore, it is possible to conduct continuous recording for long hours even without a PC for data storage use as used in conventional models.

Measurement waveform

As the product can import pieces of information including in-mold pressure, in-mold resin temperature, mold surface temperature as well as information on measurement instruments and injection molding machines from other manufacturers, and display them with the time axis synchronized, it can be used for more advanced analysis.
