Industry & Occupation
Classification
Summary
This occupation involves blending raw materials such as natural rubber and synthetic rubber in specified ratios, kneading and pasting them to produce rubber compounds.
Description
Raw rubber manufacturing workers are responsible for mixing natural rubber, synthetic rubber, and additives in specified ratios, and kneading them using kneaders or paste mills. They manage temperature and viscosity, perform degassing to prevent air entrapment, and produce rubber compounds with the required physical properties. To maintain product quality, they create test pieces and conduct physical property tests such as hardness and tensile strength, adjusting compounding ratios or process conditions based on the results. Daily machine maintenance and cleaning are also essential for stable production line operation.
Future Outlook
Although demand is decreasing due to the reduction of domestic production bases and advances in automation, skilled workers capable of advanced quality control techniques and manufacturing efficiency improvements will continue to be needed.
