Temperature Control During Heat Shrinking Of Pre-insulated Sleeve

During the heat shrinking process of pre insulated sleeve, the operating temperature must be within the shrinkage temperature range designed for the material to ensure that the shrinkage behavior meets expectations. During the engineering implementation phase, technicians often adjust the heat source equipment according to the temperature specifications provided by the manufacturer, so that the heat application time and heat transfer efficiency reach the temperature range required by the material.

When using a heat gun or heat shrink oven, it is essential to ensure that the heat flow covers the entire outer surface of pre insulated junction sleeve and to monitor temperature changes to maintain the shrinkage range. Too low a temperature will cause the insulated joint sleeve to fail to achieve the designed dimensional shrinkage, while too high a temperature may cause material aging or degradation of mechanical properties.
