Casting welding roller frame is made of liquid polyurethane rubber tire roller rubber produced by a casting method, it is compared with the ordinary wheel, it has the following characteristics:

1. The high mechanical strength (2-3 times natural rubber), excellent abrasion resistance (5-10 times natural rubber), outstanding resistance to compression;

2. The wide range of hardness and still under high hardness with high elasticity (which is not available to other types of plastic properties);

3. The surface finish; excellent machining performance; much higher than ordinary metal bonding rubber, more suitable for certain wire-speed and high-pressure use.

Recently welding roller stand polyurethane rubber tire developed rapidly, a large number of ordinary rubber tire has been replaced by the original use of the new polyurethane rubber tire.
