How does the heat shrinkable tube manufacturer solve the problem of abnormal quality?

The heat shrinkable tube is subjected to heat shrinkage through radiation cross-linking. It has high requirements on the process and material. The heat shrinkable tube plays an important protective role and has high quality requirements in its application. Then if the heat shrinkable tube How do manufacturers solve quality problems?
   Heat-shrinkable tube quality requirements: After the heat-shrinkable tube is expanded, the product has a smooth appearance, no trace, no obvious pressure line, the inner diameter of the whole tube is consistent, and the longitudinal stretch, high temperature resistance, and insulation performance must be within the established standards.
   Common abnormal quality problems and solutions for heat shrinkable tubes:
1. The heat shrinkable tube has certain requirements for the smoothness of the appearance. If the heat shrinkable tube has small protrusions and large protrusions, it is mainly a problem of semi-finished products. It is recommended that the hybrid filler improve the process conditions of more detailed and pressed tubes to ensure qualified semi-finished products.
2. If the heat shrinkable tube has cracks during the heating and shrinking, the filler may be incompatible with the resin, and the high radiation dose will lead to a low expansion temperature. To activate the filler, improve the compatibility of the filler and the resin, reduce the dosage, and increase the expansion temperature.
3. After normal heating, if the surface of the heat shrinkable tube is sticky, it can be expanded, a larger flip edge can be added, and a lower radiation dose can be used to improve it.
4. After the expansion and contraction of the heat shrinkable tube, if the tube becomes shorter and stretched larger, the resistance of the fixed diameter sleeve can be reduced, and the tetrafluoroethylene sealing sleeve will improve the situation in some gases.
The above are the relatively common quality abnormalities of heat-shrinkable tubes. This requires heat-shrinkable tube manufacturers to pay more attention to the production process and continuously improve their own production processes. Shenzhen Shunbo Insulation Material Manufacturing Co., Ltd., as a domestic heat-shrinkable tube manufacturer, has With advanced production technology and equipment, we can currently provide a variety of high-quality heat shrinkable tubing products.
