5 methods of making tungsten needle pin
1. Drawing Method
The tungsten rod is machined by drawing to make a tungsten needle pin of the required size and shape.
2. Tungsten wire drawing method
Press tungsten powder into a rod shape, then draw it through tungsten wire, and machine it to make a tungsten needle of required size and shape.
3. Sputtering method
In vacuum or inert atmosphere, use sputtering technology to deposit tungsten on the substrate to form tungsten needles of required size and shape.
4. Chemical vapor deposition method
A tungsten deposition layer is generated on the surface of the substrate by using a chemical reaction. After multiple reactions, customized size and shape tungsten needles will be finished.
5. Thermal processing
Processing tungsten rods into tungsten needles of required size and shape through thermal processing processes, such as forging, rolling, extrusion, etc.
