Tungsten Carbide Fan-shaped Blade

Tungsten carbide fan-shaped blade has the characteristics of high hardness, high compressive strength, high temperature resistance, good wear resistance, good chemical stability (acid resistance, alkali resistance, high temperature oxidation resistance), low impact toughness, small thermal expansion coefficient, and long working life.

At present, manufacturers generally use powder injection molding method to process tungsten carbide blades. The powder injection molding process is particularly suitable for mass production of small-size and complex-shaped products. However, powder injection molding requires an injection molding die. The traditional injection molding die has disadvantages of complicated structure and complicated operation. The fan-shaped blade is relatively thin. And it is relatively complicated to take out the blades after processing. So, it greatly reduces the processing efficiency. In addition, it is often expensive to manufacture complex injection molding mold, which increases manufacturing costs. In order to solve the shortcomings of the existing technology, the researchers focused on the development of powder injection molding molds of fan-shaped blades, and achieved the goal of better and faster production of tungsten carbide fan-shaped blades.
