1. Initial Inspection     
Initial inspection for aircraft tire is to do visual inspection and press testing inspection to decide whether the tire can be retreaded or not.    
Equipments involved:  Inspector KTJ, pressure testing machine CQJ, shearography.

2. Buffing
Buffing is to remove the old, worn tread surface. Before buffing, put tire in FMP and inflate it. Choose the parameter option in user interface according to different sizes and then buffing machine will operate automatically.
Equipment involved: Computerized Numerical Control (CNC) Buffer FMP

3. Skiving
Skiving means polishing the mendable broken parts and then repairing the small holes.
Equipments involved: skiving machine, pneumatic rubber extruder

4. Building
Tire building means gluing cushion gum and suited tread to the polished tire under the help of tire builder.
Equipments involved: latex mixer, YLT builder

5. Curing
Curing is a process of integrating unprocessed tread rubber and casing. During the curing process, tread rubber will gradually become tough, durable and with good driving. Firstly, Put pre-cured tire into the mold and close it. Then, inflate the tire to proper curing pressure. As a result, inflated tire will press uncured tread into the mold and patterns on tread will take shape. After a certain time of heat and pressure, the cure of tire will be done.
Equipment involved: HFL-1250*500 segment curing press

6. Final Inspection
Final Inspection is to inspect all the treated tires thoroughly to make sure high quality.
Equipments involved: Spreader KTJ, CQJ pressure testing machine, Shearography, dynamic balance inspection machine)
