Wire drawing
Thin and ultra-thin wires manufactured by workers by repeatedly passing thick wires through dies in a careful manner, using our original wire drawing machines.
Hard-to-work materials such as tungsten and molybdenum can produce ultra-thin wires with minimum diameter of up to Φ0.01 mm by heating and drawing wires.

Product types of molybdenum wires
Pure molybdenum wires used
TMG
◉Soft wire drawing process
Capable of drawing wires ranging from ø0.95 to ø0.009 mm in diameter. Capable of drawing various types of wires made of copper alloy, iron-nickel alloy, stainless steel, brass and piano wires (cold wire drawing), and manufacturing surface-treated (plated) drawn wires and the high-straightness products and flat-surface ones by heat treatment.
