EFFECT OF THERMAL CONDUCTANCE TO MOLD ON THE TEMPERATURE RISE MEASURED BY RESIN TEMPERATURE SENSORS

摘要

In order to identify the resin state precisely, the measured temperature should be closer to the actual resin temperature and sensitive to the resin temperature variation. In an absolute sense of view, the measured temperature by the resin temperature sensor is a mold wall temperature. In this study, we examined the effect of thermal conductance through the sensor from the resin to mold on the temperature rise measured by the sensor. In experiment we tested a thermally insulated washer and an insulation block to reduce the thermal conductance. To examine the influence of thermal conductance of mold material, the temperature rise of mold wall was calculated with different thermal conductivity of the mold by transient-heat-transfer numerical simulation.
