Parts of Retread process
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.
