AI Technical Summary
Existing methods for manufacturing retreaded vehicle tires do not effectively enhance the properties of the tread, particularly in terms of braking performance on wet roads and rolling resistance, and lack efficient utilization of waste heat generated during the vulcanization process.
A method involving slow cooling of the pre-vulcanized tread in a preheated environment using waste heat from the vulcanization process, combined with a device that includes a press mold and a preheated chamber or tunnel for cooling, followed by deburring or trimming to remove excess material.
Improves braking performance on wet roads and reduces rolling resistance of retreaded tires while increasing energy efficiency by utilizing waste heat, resulting in a more effective manufacturing process.
