Concepts of cold retreading:

The low temperature is against the high hot retreading temperature. Generally, 120°C is the denatured point of rubber, over called hot retreading, blow called cold retreading. And more advanced technology allows the temperature below 100°C. Because of the high temperature produce a negative effect to the tyre, the cold retreading is more and more popular.

Precure retreading means the tread should be procured by the high-pressure vulcanizing machine separately, while the hot retreading means the tread and casing are made up with non-vulcanized rubber, so the tread pressure is far below than the cold retread technology. Therefore, wear resistance, mileage of cold retread tyre can be comparable to the new tires, and flat mould can make tread with kinds of patterns, help the users to choose the more suitable patterns. However, it will be a big expense if you change tread patterns with hot retreading technology.

1, cleanness and dry of casing

Before retreading, outer and inner surface should be cleaned for good adhesion strength. Drying is also essential because the water in casing would affect the retreading quality.

2, tyre inspection

Not all the used tyres can be retreaded, different standard for different conditions. Some defects can be found directly by the experienced operator, but some inner ones can only depend on the inspection of equipment and devices.

3, buffing

Obtained tire surface with a certain profile and adhesion after buffing. It should be stressed that this is a crucial process, because unqualified tire size, roughness, or roundness would affect the quality of retread tires.

4, skiving

Buffer can not grind the pattern grooves and the concave parts caused by using, so can only use hand-held pneumatic or power tools with special grinding wheel. In addition, the uncertain damage can be confirmed exactly and remarked.

5, cement

In order to prevent the grinding tread surface to be oxidized in the long-time exposure, and to provide operating viscosity to next adhesion step, the operator paint a thin cement layer on the polished surface. Spray cement has been eliminated in some advanced plant, because the wet cement would affect the adhesive property and has flammable risk.

6, repairs

Cuts repair, fill, paste patch liner depend upon complete tools in this station. By scientific design, high strength, light weight, resistance to flex, the patch liner can be prefabricated into a variety of models. Right models with correct operation lead to reliable quality. And it should be noted that all the work is operated manually, so need the operator have proficient skills and responsibility.
