New Generation Curing Chamber Truck Tire Retreading Equipment
9, curing assembly
Encase the uncured, built tire in an elastic envelope in preparation for curing. The envelope is a flexible rubber mold. Under pressure, the envelope can adapt itself to the tire shape, so there is no internal stress. While hot retreading use rigid mold. But the used tyres are so different that they can not match with the rigid mold completely, and produce a pressure. Therefore the use of envelope is better than rigid mold.
Assembly methods
Traditional method is wrapped envelope, inner rube assembly and curing rims. Now the bias tires still use above method. With the development of radial tires, ARC central and dual-packet envelope methods are more and more efficiently, saving time and energy.
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.
