Cimcorp AI is making tire manufacturing automation even more of a game-changer

Unlike traditional automation that relies on predefined instructions, AI-driven systems learn, adapt and make real-time decisions through machine learning and data analysis. This shift enables businesses to handle complex, dynamic environments with greater flexibility and precision, continually improving and optimizing based on real-world conditions. AI-powered automation predicts needs, identifies inefficiencies and evolves with each interaction, facilitating faster and smarter decision-making, without human intervention.

UNC researchers pioneer chemical process to repurpose rubber waste

The University of North Carolina at Chapel Hill researchers introduce a sulfur diimide reagent that enables the installation of amine groups at specific locations in the polymer chains. This step is crucial because it sets the stage for the subsequent backbone rearrangement. This chemical reaction reorganizes the polymer backbone, breaking down the rubber into soluble amine-functionalized materials that can be used to produce epoxy resins.

The researchers showed that their two-step process works very well. In a test with a model polymer, they broke it down significantly, reducing its molecular weight from 58,100 g/mol to about 400 g/mol. When they applied the method to used rubber, it broke down completely in just six hours, turning it into a soluble material with amine groups that could be used to manufacture broadly useful materials like epoxy resins.

Truck tire tread compound development using low hysteresis carbon black

Performance properties of a surface treated low hysteresis carbon black (Continext-LH) compound in a natural rubber tread formulation are compared with those of a conventional N234 low hysteresis version and show that the new material had significantly improved rolling resistance and directional improvement in damage resistance without negative effects or trade-offs in wet traction and wear resistance.

Yokohama tests AI to gauge air pressure by sound

The Yokohama Rubber Co., Ltd., has begun practical testing of a technology that uses artificial intelligence (AI) to gauge air pressure from the sound made by tapping truck and bus tires. Using AI to gauge tire air pressure from the sound made by tapping the tire, which previously relied on the driver’s experience, will provide logistics companies with solutions to various issues, including safe vehicle operation via improved air-pressure measurement, cost reductions and greater operational efficiency through labor-saving, and raising fuel efficiency by appropriately managing tire air pressure.
