Drag chain is also known as Cable carrier.  It is a device for binding cables, wires, air pressure tubes and oil pressure tubes to facilitate their rotation and movement. Drag chain is divided into steel drag chain and plastic drag chain.  Steel drag chain made of steel and aluminum can be customized.  Plastic drag chain is also known as engineering plastic drag chain.  According to the different operational environment and requirements, drag chain is divided into bridge Drag chain, fully closed Drag chain, semi-closed drag chain three. 

1. Material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant, stable performance at high and low temperature, can be used outdoors.  

2. Resistance: oil resistance, salt resistance, and a certain acid, alkali resistance.  

3. Speed and acceleration depend on operation: capable of running at high speeds over long distances, and capable of acceleration and emergency stops.
4. Each link of the drag chain can be opened for easy installation and maintenance.

Drag chain is used in reciprocating motion, which can play a role of traction and protection to the built-in cable, oil pipe, gas pipe, water pipe, etc.  Drag chain has been widely used in CNC machine tools, electronic equipment, glass machinery, injection molding machine manipulator, handling machinery, plastic machinery, lifting equipment, woodworking machinery, automobile industry, industrial vehicles, metal processing machines, machine tools, casting machinery, port equipment and other industries.
