TIRE MANUFACTURING TECHNOLOGY

Abstract

This article describes the step-by-step tire manufacturing processes. The process begins with the acceptance of rubber and other materials based on State Standards or Enterprise standards. Then, natural rubber is subjected to a decrystallization process, as this process converts the rubber's crystalline structure into an amorphous state, improving its workability. After decrystallization, the rubber undergoes plasticization and granulation processes. During the plasticization process, the rubber's viscosity decreases and its plasticity increases due to mechanical and thermal treatment. This process is carried out using rollers and screw plasticizers. In the plasticization process performed in rollers, a reduction in the rubber's molecular mass and oxidation are observed, which improves the quality of the rubber. The temperature and rotational speed of the rollers play a crucial role during the process. After plasticization, the rubber is briefly stored, and its technological properties are analyzed. This article highlights the important stages of material processing technology in tire manufacturing.
