Melt Flow Indexers


The Mi-Robo is a fully automatic melt flow rate measurement equipment which performs the process automatically including sample loading, cleaning and die changing according to ISO1133 and ASTM D1238 standards for granulate as well as powder materials. This also means fully automated filling and cleaning of the barrel before and after the measurement and automatic process of measurement.


  • Integrated sample magazine for 30 or 45 single tests, to fill with plastic granules, powder etc.
  • Electric linear drive for weight handling system with permanent position control (±0,02mm). So the pre-loading, pre-heating and feeding positions for each test are free definable via parameter. No more sensors must be adjusted.
  • Time saving, force controlled pre-loading and ejection of the test material via drive and test weights (up to 60 kg) especially when testing viscous materials. Therefore, force can be defined step less.
  • Reduced air consumption (< 5 m3/h, only 30% of consumption of the former model 89.07), because of low-noise electric drives.
  • Positioning of all cleaning tools with one single linear drive. Each cleaning tool operates via force control to get an optimum of pressing force.
  • Completely integrated cleaning cloth feeding inside the device and comfortable exchange of the cloth roll at the front side of the device.
  • Piston cleaning unit moves faster and more reliable via electric positioning instead of pneumatic cylinder.
  • Cleaning module, with or without die cleaning (necessary option). The unit can now be equipped with fully automatic die cleaning.
