Industry & Occupation
Classification
Summary
Manufacturing worker who draws out glass fiber from a molten state, bundles it, and forms and processes it into a rod shape.
Description
Rod Worker (Glass Fiber Processing) is responsible for heating raw glass in a melting furnace, drawing out thin glass fibers from a bushing (die), bundling multiple strands, and forming them into a rod shape (roving rod). Main tasks include operating drawing equipment, managing drawing speed and temperature, applying resin sizing to fiber bundles, winding and cutting rods to specified lengths, and inspecting product weight and dimensions. Temperature adjustments to maintain quality, defect detection, and safety and health measures are required. Products are widely used as reinforcing materials in composite materials for automobiles, construction, aviation, wind power generation, and more. Work often involves standing in factories, shift schedules, and requires safety management and attention in high-temperature environments.
Future Outlook
With the expansion of demand for composite materials, the demand for glass fiber rod processing technicians is expected to continue steadily. Usage in fields such as automobiles, construction, and wind power generation is increasing, and the market value of workers skilled in automation technology and quality management will rise further.
