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. In the past, there were two main methods for making cable signs in my unit:

(1) Stainless steel sign: Cut into a T-shaped blank with a 0.5mm thick stainless steel 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 above cable signs cannot meet the needs of modern electronic products due to limitations in materials, forms and manufacturing processes. To this end, we have adopted a new type of heat-shrinkable signage tube signage, and adopted a computer-aided design process for the production of signage content and the corresponding signage assembly process.

The heat shrinkable signage sign is produced by Guangzhou Kehong Electronics Co., Ltd. The signage content is designed with the company's signage design software and printed on the casing with a thermal transfer printer. Then place the label on the end of the cable and heat up and shrink.

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.

热缩标识管在电子行业内的应用
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.以前我单位电缆标牌制作工艺方法主要有以下两种:
(1)不锈钢标牌:用0.5mm厚的不锈钢板剪成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。
上述电缆标牌由于材料、形式及制作工艺等方面的限制,无法满足现代电子产品的需要。为此我们采用了一种新型的热缩标识管标牌,并采取了计算机辅助设计制作标牌内容的工艺方法和相应的标牌装配工艺。
这种热缩标识管标牌是由广州柯鸿电子有限公司生产的,标牌内容用该公司的标牌设计软件设计,用热转印打印机打印在套管上。然后将标牌套在电缆端头并加热收缩。
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。
