Rough Mix Rubber Worker (Raw Rubber Processing)
そこんごむこう
Industry & Occupation
Classification
Summary
A manufacturing job that weighs and compounds raw materials such as natural rubber or synthetic rubber, and kneads them together using a mixing machine.
Description
Rough mix rubber workers weigh additives such as carbon black, silica, oil, and vulcanization accelerators in prescribed ratios with natural or synthetic rubber, and knead them in a mixing machine (e.g., Banbury mixer). They manage mixing time and temperature to maintain the accuracy of compounding ratios and the uniformity of the mixture, as well as create manufacturing records and perform simple inspections and cleaning of machines and equipment. For quality inspection, they measure appearance, viscosity, and temperature, and supply rubber compounds that conform to standards to the next process.
Future Outlook
While work efficiency improves due to advances in automation and labor-saving measures, demand for rubber products remains stable. The inheritance of skilled workers' techniques is important due to needs for environmentally responsive compounding technologies and new material development.
