The heat shrinkable identification tube may also be referred to as a heat-shrinkable tube, or a line number tube and a number tube. The heat-shrinkable tube is printed with a printing wheel and an auxiliary material such as a ribbon or ink to mark the heat-shrinkable sleeve. Printing needs to choose a machine with better compatibility, because the surface of the heat shrinkable sleeve is attached with some chemicals, and some machines are not compatible enough, which will cause the batch of heat shrinkable sleeves to be printed, and the next batch will not be printed. Stability. This is very troublesome. The choice of heat shrinkable sleeve printer must first consider the size of the heat shrinkable tube to be printed. If the surface after flattening is within 15mm, it is necessary to use a small machine. The heat-shrinkable sleeve printer with good stability and positioning can print a thick heat-shrinkable tube. It can be a special heat-shrinkable tube printer. This is a machine specially designed for heat-shrinkable tube printing. The effect before and after heat shrinking is very clear. The heat shrinkable tube of φ7-φ30 can be easily handled, connected to the computer for editing and printing, and can be imported into the Excel table for batch editing and printing.


The function of the heat shrinkable identification tube: the cable heat shrinkable identification tube, also known as the identification number tube, the label tube, the printing sleeve, is used for marking the cable, and is surface-treated on the basis of the heat shrinkable sleeve and printed on the surface. Word, used to distinguish between different lines, convenient for maintenance management. Typing on the heat-shrinkable tube can be divided into a thick tube and a thin tube. The thin heat-shrinkable tube can be printed with a wire number machine, and the Shuofang line machine can print a heat-shrinkable tube of φ0.5-φ6.0 and a PVC sleeve ( Number tube), 6/9/12mm wide sticker.

Commonly used printing equipment for heat shrinkable tubes:

1, inkjet printer (high equipment investment)

2, pad printing machine (suitable for large diameter thick pipe)

3, line number printer (suitable for Φ8 or less)

4, printing wheel

5, label printer (suitable for flat tube)
