How to control the quality of tire rubber during the production process?

Controlling the quality of tire rubber during the production process is key to ensuring tire performance and safety. Here are some effective methods to control the quality of tire rubber production:

1、 Raw material quality control

Strictly screen rubber materials:

Select high-quality natural rubber and synthetic rubber to ensure that the abrasion resistance, aging resistance and elasticity of rubber materials meet the production requirements.

Strict physical and chemical performance tests are conducted on rubber materials to ensure their stable and reliable quality.

Strengthen the management of additives:

Strictly control the types and amounts of additives such as carbon black, sulfur, and accelerators to ensure the optimal balance of tire rubber performance.

Additives should be stored in a dry, ventilated, and dark environment to avoid moisture, deterioration, and contamination.

2、 Production process control

Standardize the mixing process:

Strictly follow the formula and process requirements for mixing to ensure the uniformity and dispersion of the rubber material.

Control the mixing temperature and time to avoid overheating or overcooling of the rubber material, which may affect its performance.

Optimize extrusion molding process:

Select appropriate extruders and molds based on tire specifications and pattern design requirements.

Control the extrusion temperature and speed to ensure that the rubber material can be smoothly extruded and filled into the mold.

Regularly inspect and maintain extruders and molds to ensure their normal operation and accuracy.

Strengthen the control of vulcanization process:

Strictly control the parameters such as vulcanization temperature, time, and pressure to ensure that the cross-linking degree and hardness of the tire rubber meet the standards.

During the vulcanization process, good ventilation and exhaust should be maintained to avoid the formation of bubbles and defects.

3、 Quality inspection and monitoring

Raw material inspection:

Strictly inspect and test each batch of raw materials to ensure their quality meets production requirements.

Establish a raw material quality traceability system so that problems can be traced and addressed in a timely manner.

Production process monitoring:

Set up multiple quality inspection points during the production process to monitor and detect key processes in real-time.

Regularly maintain and calibrate production equipment to ensure its accuracy and stability.

Finished product testing:

Conduct multiple tests on the durability, high-speed performance, and wetland performance of finished tires to ensure that their performance meets the standards.

Timely analyze and handle non-conforming products to avoid them entering the market.

4、 Personnel training and management

Strengthen employee training:

Regularly provide quality awareness and skill training to employees to improve their quality awareness and operational skills.

Encourage employees to actively participate in quality improvement activities and provide rational suggestions and opinions.

Establish a quality management system:

Establish a comprehensive quality management system and clarify the quality responsibilities and authorities of personnel at all levels.

Regularly audit and evaluate the quality management system to ensure its effective operation and continuous improvement.

In summary, controlling the quality of tire rubber in the production process requires starting from multiple aspects such as raw material selection, production process control, quality inspection and monitoring, as well as personnel training and management. Only by comprehensively strengthening quality management can we ensure the stable and reliable quality of tire rubber, providing strong guarantees for the performance and safety of tires.
