Abstract:The reasons for the fluctuation of tire tread extrusion quality were analyzed and the corresponding solutions were put forward.The main reasons for the fluctuation of tread quality were the fluctuation of raw material properties,unstable final stock properties,fluctuation of extrusion tread size,difference in the parking time of the final stock,operational differences,unscientific quality control method of the extruded tread and mismatch between the process and the equipment.By adopting measures such as improving the control of the procurement of raw materials,strictly controlling final stock properties,improving the dimensional control accuracy of the extruded parts,controlling the parking time of the final stock,eliminating the difference of operation,adopting an automatic screening system for the quality of the extruded parts,and ensuring the matching of the process and the equipment,the tread quality was stabilized and the qualified rate of the finished tire was greatly improved.
