What Is the Manufacturing Process of Tungsten Carbide Needle?

Tungsten carbide needle is a slender needle-shaped tool made of tungsten steel (tungsten carbide), which is commonly used in mechanical processing, electronics, optical instruments, aerospace and other fields. The following will introduce in detail the manufacturing process, material characteristics, application fields and usage precautions of tungsten carbide needles.

Manufacturing process

The manufacture of tungsten carbide needles requires a series of precise processing and manufacturing processes. First, high-purity tungsten steel powder is selected as raw material, and a cemented carbide body with a certain shape and size is made through processes such as pressing and sintering. Then, a series of machining processes such as turning, milling, drilling, etc. are performed to obtain the required elongated needle-like shape and precision. Finally, heat treatment and surface treatment are performed to enhance its hardness and corrosion resistance.
