High-Efficiency Curing Chamber For Tire Regrooving Equipment
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.
10, vulcanization
A curing chamber applies heat and pressure, and over time, causing the bonding layer to cure, permanently adhering the new tread to the prepared casing. If there are any problems in vulcanizing, it will make the retreading tyres to gap. The tyres for truck need several hours to vulcanize, need the experienced and responsible operators. Now the advanced plants adopt the curing chamber auto controlled by computer, which can complete vulcanize automatically and exactly.
11, final inspection
A final inspection is performed to ensure the tire in perfect operating condition depending visual, hands-on inspection. In some countries and regions, the finished product must be checked in high gas-pressurized state, but special protective equipment is necessary to reduce the operation risk. Laser non-destructive checking equipment has been used in some advanced plants. By spraying paint, the qualified production can be put into use after 24 hours.
