Nitrogen curing tires has many advantages, such as:shorten the curing time and provide labor productivity; saving energy and reducing curing costs; because the purity of nitrogen can reach more than 99.9% and is close to inert gas, there is almost no corrosion of valves and pipes. The maintenance and its cost have been largely reduced;lmproved the service life of the capsule.;the investment in equipment and infrastructure has been reduced, the quality of the tire has been improved, the waste rate has been reduced, and the operating environment also be well improved.

The advantage of the self-made nitrogen system is: one-time investment is high but theoperating cost is less.

The basic process of the liquid nitrogen system is as follows: the liquid nitrogen is stored inone liquid nitrogen tank, then goes into high-purity nitrogen through the vaporizer. The subsequent process is similar to the self-made nitrogen described above. The advantage of this system is: less investment. Disadvantagesare: high operating costs, easy to be limited by the production conditions, prices and other conditions of liquid nitrogen suppliers.
