INNER MELT PEAK PACK TEMPERATURE END PRESSURE SENSOR

摘要

A thermocouple profiling temperature and inner melt pressure flow from fill to peak pack is presented. The mold close processing cycle varies the melt cavity fill to peak pack volume. Mold close starts the gas venting indicates injection start. The heated melt front flow temperature and low pressure encloses the sensor as melt flow progresses to pack point. The static outer melt skin and final inner melt pack pressure occurs at gate seal. After inner melt packing stops the volume shrink cure starts. The shrink rate is dependant on final peak pack volume and melt temperature peak.
