Classification

Summary

Manufacturing technician who produces glass bottles for thermoses and performs sealing after blow molding or press molding.

Description

Sealing workers are on-site operators who manufacture glass bottles for thermoses (vacuum insulated containers). They melt glass raw materials in a melting furnace, form the bottle body using blow glass or press molding machines. After removing internal stress in an annealing furnace, they use sealing machines to seal (close) the bottle, finishing it into a structure that maintains a vacuum state. Main duties include machine operation on the production line, quality control through dimensional measurement and appearance inspection, and compliance with safety and hygiene.

Future Outlook

Although demand for vacuum insulated containers is stable, automation and labor reduction are progressing, and demand for manual labor is decreasing. Acquiring advanced quality control skills will increase market value.
