Industry & Occupation
Classification
Summary
A job that manufactures homogeneous rubber compounds by blending raw rubber and auxiliary materials in specified ratios for use in the next process.
Description
Raw rubber compounders weigh raw materials such as natural rubber, synthetic rubber, vulcanizing agents, softeners, and fillers, then mix and heat-treat them in prescribed blending ratios using kneaders (Banbury mixers or mixers) to produce uniform mixed rubber. They strictly adhere to work procedures and kneading conditions (temperature, time, rotation speed), and perform quality inspections and physical property checks through sampling. They also handle daily machine inspections, simple maintenance, and safety and health management, supporting stable supply and high quality in the manufacturing line.
Future Outlook
With advances in automation and IoT in manufacturing sites, operator proficiency and quality management skills are increasingly emphasized. Amid population decline and skilled worker shortages, demand for personnel proficient in machine maintenance and safety hygiene is expected to remain high.
