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.
