Support Strip for Cold Shrinkable Cable Accessories

2022-11-25
The main manufacturing processes of the support strip of Cold Shrinkable Cable Accessories are crimping, ultrasonic welding and hot air welding. Crimping and ultrasonic are widely used, hot air welding is relatively less used, and the manufacturing process of Cold Shrinkable Cable Accessories support strip is relatively simple.

The Cold Shrinkable Cable Accessories support strip is made of polypropylene as raw material, extruded into a strip of ribbon with the gripping buckle, and then pressed into a cylinder with a specific inner diameter by a special machine, which is cut off according to a specific length. The two ends are spot welded firmly with a welding gun to prevent it from loosening. After the expansion of various components of the Cold Shrinkable Cable Accessories, one end is reversely passed through the support strip and stretched. That is, the spare lead wire is installed, and then the lead end is welded and made into finished Cold Shrinkable Cable Accessories.

PP material is cheap, high strength, simple production, mechanical equipment is relatively simple, the internal binding force of the support strip is more uniform, when the installation and extraction, the force is good control, convenient to adjust the shrinkage progress.

If the production process is not perfect, improper material selection may cause the support strip to collapse, not firm enough, so that the entire Cold Shrinkable Cable Accessories failure and can not be installed, at the same time, the production process is more complicated, more labor cost, it is difficult to realize mechanization, automatic continuous production.

When winding the tube, instead of using self-crimping, ultrasonic wave is used to partially melt PP raw materials to form a melting point bonding together, no special spot welding is required before stretching the head.

The process saves labor, the joint strength of the solder joint is large, the support strip is not easy to deformation, and can be transformed into continuous automatic production. The support strip of Cold Shrinkable Cable Accessories mainly affects the user experience during installation and the integrity of the product before installation. A good support bar will make cold shrinkable products more reliable. The support strip of Cold Shrinkable Cable Accessories plays a more important role.
