Abstract

The paper addresses the current problem of increasing the efficiency and quality of pneumatic tubes production for large-size tires at АO “Industrial Group “Altayskiy Shinnyy Kombinat”. The analysis of the existing technological process using a hot-feed screw press MChT-400 identified its key disadvantages: contamination of the rubber mixture, unstable wall thickness of the workpiece and low dispersion of components, which leads to increased defects and excess consumption of raw materials. As a solution, the researcher proposes a modernization of production by replacing the extruder with a cold feed machine MChKh-250. The technological advantages of this transition are substantiated, including improved homogeneity of the mixture, stabilization of the geometric parameters of the workpiece and a decrease in the number of foreign inclusions. The calculation of economic efficiency is given, showing that the introduction of new equipment will reduce the weight of each chamber by an average of 1.75 kg and achieve annual savings of 24.68 million rubles with a project payback period of 8 months. In conclusion, the modernization contributes to a significant increase in the competitiveness of products due to a decrease in material consumption and an improvement in the quality of finished products.
