Heat-shrinkable identification tube: made of cross-linked environmentally-friendly polyolefin heat-shrinkable material, the substrate has a memory function, the surface is specially treated, and the font has permanent identification.

In the electronic whole machine assembly, in order to facilitate production, debugging, maintenance, and testing, it is often necessary to mark the end of the assembled cable, that is, to make a cable label.

There are many ways to make cable signs. There are two main methods for making cable signs:

(1) Aluminum sign: Cut into a T-shaped blank with a 0.5mm thick aluminum plate, and engrave the characters on the blank by hand-cutting machine and pre-made font. This kind of process is labor-intensive, time-consuming, and efficient, and is not suitable for mass production. Moreover, the signboard has poor vibration resistance and is easy to loose, and cannot be used on airborne and aerial electronic devices.

(2) Plastic casing sign: that is, hand-written characters on the plastic casing. The characters of this sign are neither beautiful nor clear, the sign can only be used under normal temperature conditions, and the service life is short and easy to age.

The use of the sign and the process method to make the cable sign is very convenient and flexible, can print a variety of characters, and the writing is clear and beautiful, the signboard is better than the aluminum sign and the plastic sign in the anti-vibration, anti-corrosion and anti-humidity performance.

热缩标识管：用交联环保聚烯烃热缩材料制成，基材具有记忆功能，表面进行特殊处理，字体具有永久标识性。

在电子整机装联中,为了便于生产、调试、维修、检测,常需对装联电缆的端头作标记,即制作电缆标牌。

制作电缆标牌的工艺方法有很多，电缆标牌制作工艺方法主要有以下两种:

(1)铝标牌:用0.5mm厚的铝板剪成T形毛坯,通过手工刻字机和预先做好的字模.在毛坯上刻字符。这种工艺方法,费工费时,工作效率底,不适合批量生产。而且标牌的抗振动性差,易松脱,在机载和航载电子设备上无法使用。

(2)塑性套管标牌:即在塑料套管上用手工书写字符。这种标牌的字符既不美观也不清晰,标牌只能在常温状态下使用,且使用寿命短,易老化。

使用该标牌及工艺方法制作电缆标牌非常方便灵活,可打印各种字符,而且字迹清晰美观,标牌的抗震、抗腐蚀、抗潮湿性能都优于铝标牌和塑料标牌。
