Industry & Occupation
Classification
Summary
A job that manufactures hard rubber products through processes from kneading to vulcanization, molding, and finishing using ebonite as raw material.
Description
Ebonite workers use hard rubber (ebonite) mixed with sulfur as raw material, performing kneading in mixing machines, calendering with rolls, vulcanization molding with presses, and finishing such as polishing and deburring to manufacture products for diverse applications like insulating materials for electronic components and sealing parts for medical devices. They operate machines on production lines, manage temperature and pressure, conduct quality inspections to ensure product dimensions and properties, and handle equipment maintenance and safety/hygiene management.
Future Outlook
While demand for insulating materials for electronic and medical devices continues, the industry is in a shrinking trend due to the rise of synthetic resin materials. Skilled workers in high-value-added products can expect steady demand.
