[0002] Aircraft tires must withstand extreme operating conditions (such as high impact, high load, and high temperature during takeoff / landing), placing extremely high demands on the strength, heat resistance, and fatigue resistance of the sidewall rubber. As the area of ​​greatest tire deformation, the sidewall must possess excellent flexural strength and tear resistance to ensure flight safety. Aircraft tire sidewalls require a multi-layered composite rubber structure, and the extrusion device must ensure uniform rubber density and thickness to avoid internal defects. Therefore, an aircraft tire sidewall rubber extrusion device has emerged.
