The spring wire, also known as the slingshot wire and the helical wire, is a kind of equipment connection wire that uses the flexibility to work. Generally made of TPU cable winding. The power connection used to control the movement of movable equipment can quickly rebound in a short time, and is widely used in movable equipment such as automobiles, machines and meters. The following are the advantages of spring wire:

Spring wire is generally made of TPR/TPU/TPE/PVC cable. The most used is PU/TPU. PU/TPU is thermoplastic polyurethane (TPU) elastomer, which is a non-toxic and environmentally friendly polymer. It has high strength, good toughness, wear resistance, cold resistance, unmatched by other plastic materials. It has the characteristics of high temperature resistance, oil resistance, water resistance, aging resistance, weather resistance, etc. At the same time, it has high waterproof and moisture permeability, windproof, cold proof, antibacterial, mildew proof, warmth retention, anti-microbial, environmentally friendly flexible cable, anti-ultraviolet and energy release, etc. Excellent functionality.

The spring wire has good flexibility and elasticity (the elongation length can reach 3-4 times the original spring length). It has good cold resistance, flame resistance, oil resistance and abrasion resistance. Various types of helical spring wires can be produced according to different requirements of the occasion.

As for the industries where spring wire is used, it is necessary for almost all industries to use spring wire (spiral cable). Whether in communications (telephony, radio) or medical technology, the electric locomotive industry, mechanical engineering, or in the lighting industry, helical cables are used everywhere.
