What Is the Manufacturing Process of Tungsten Wire Needles?

Manufacturing process of tungsten wire needles

Tungsten wire needles are usually made of tungsten wire, and their manufacturing process includes the following steps:

(1) Melting: Put the tungsten raw material into a high-temperature furnace to melt it into liquid.

(2) Rolling: Pour the molten tungsten liquid into a water-cooled copper mold and roll it through a rolling mill for multiple times to gradually cool the tungsten liquid and form a thin tungsten rod.

(3) Cutting: Cut the tungsten rod into tungsten wire segments of a certain length.

(4) Grinding: Grind the cut tungsten wire segments to make their surface smooth and reach the required diameter and shape.

(5) Polishing: Use a polishing machine to polish the ground tungsten wire segments to improve their surface finish.

(6) Inspection: Inspect the polished tungsten wire segments, including size inspection, appearance inspection and performance inspection, to ensure that they meet the requirements.
