Precise melt temperature measurement made easy.
The MTMS method is based on an insulator cup that keeps the material in a molten state during the measurement process. It also precisely positions the thermocouple probe in the effective flow path. The process is shown in the embedded video. In addition to its low cost and ease of use, Bleck cites the following advantages compared with conventional technologies:
The ability to measure shot sizes under one ounce;
once the process has been stabilized, it takes only one shot to measure the melt temperature;
minimal downtime, generally under one minute;
excellent repeatability between operators.
The importance of complying with resin supplier recommendations for melt or process temperatures, which MTMS facilitates, cannot be overstated, according to Bleck. Don’t make the mistake of thinking the temperatures shown on the controller screens are actual, he cautions. “Those thermocouples are reading steel temperatures along the barrel
