説明
In this paper, the measurement of melt temperature profiles inside a nozzle was carried out using several types of screws, and the influence of screw configurations on the plastication process, especially on the temperature characteristics of the injection melt were investigated. The results can be summarized as below:<br>(1) Two common trends were seen in the temperature profiles using each screw: the generation of concentric temperature profiles at the cross section of the nozzle channel and the temperature drop towards the latter stage in the injection process.<br>(2) The increase of the screw compression ratio and feed zone length causes a drop in the average melt temperature. But, in the high compression ratio screw, the melt temperature in the latter stages of the injection process rose due to the recovery of the shearing operation in an early stage of the charging process, and temperature uniformity was observed.<br>(3) It was confirmed that barrier flight screws are very effective for obtaining melt temperature uniformity, and the barrier flight must be located in front of the compression zone to avoid overheating and time loss.<br>(4) A maximum value in the temperature variation between injection shots was seen in the case of high compression ratio and long feed screw.
