Dumet Wire Maker (Incandescent Bulb Manufacturing)
じゅめっとせんせいぞうこう
Industry & Occupation
Classification
Summary
Manufacturing job responsible for processing and shaping metal wire (Dumet wire) for incandescent bulb filaments, from assembly to quality inspection.
Description
Dumet wire makers process and shape metal wire (mainly tungsten wire) for filaments that form the light source inside incandescent bulbs. They handle processes such as wire drawing by drawing, coiling with winding machines, attaching to supports, and conductor joining by spot welding or soldering. They maintain high quality through production line machine operation, die changes, precise measurement of dimensions and resistance values, and powering tests on finished products. Additionally, work with vacuum equipment and in clean environments is required, and equipment maintenance and quality control are important tasks.
Future Outlook
While incandescent bulb manufacturing for general lighting is shrinking due to energy-saving trends, manufacturing technology for special-purpose filaments and vacuum tubes is expected to see continued demand.
