Dumet Wire Making Plant

Abstract

The dumet wire (or glass sealing copper-coated alloy wire) is the name of Fe+Ni alloy wire combined with copper. The wire is fabricated in accordance with the advanced brushless hot drawing process developed by the Korea Advanced Institute of Science and Technology (KA 1ST). The glass sealing copper-coated alloy wire is a glass sealing electric conductor which is particularly essential in the manufacture of electric bulbs. With an increasing demand for such bulbs in extensive electrification projects for farm and fishing villages in developing countries, the production of electric bulbs, one of the labor-intensive type products, is in the trend of gradually shifting to these countries from advanced nations. It is mandatory to domestically produce this glass sealing copper-coated alloy wire which is a basic material for manufacturing electric bulbs.
