Silicon nitride forming wheel is a forming wheel made of silicon nitride ceramic material, which has excellent high temperature resistance, corrosion resistance, high strength, high hardness and other properties. This forming wheel is suitable for forming processes in various harsh environments such as high temperature, high pressure, and high corrosion.

Our company’s silicon nitride forming wheel production range is: inner diameter from Φ3mm to Φ150mm, length from 5mm to 300mm. Silicon nitride forming wheels of different specifications and shapes can also be customized according to specific application scenarios and needs to adapt to different forming processes and production requirements.

Advantage of Silicon Nitride forming wheels

-Has longer service life. The life of the silicon nitride ceramic forming wheel is more than 10 times that of the stainless steel forming wheel, and 2 to 3 times longer than that of the tungsten carbide forming wheel;

-Ability to operate at higher temperatures. Silicon nitride ceramic forming wheels can work at high temperatures of 1000°C, while steel forming wheels generally have a maximum working temperature of 300°C;

-The surface finish of processed metal parts is higher;

-No such undesirable phenomena as pull scratches;

-Good accuracy and consistency

-Reduce scrap rate

-Increase production capacity

Application of Silicon nitride forming wheels

Silicon nitride forming wheels are used in the metal wire and coil processing industries and can be used for guiding, extruding, rolling, stretching and other processing of various metal bars, pipes, wires and special-shaped materials.

Packing

Silicon Electrical forming wheels use appropriate outer boxes and internal buffer materials, and some components are also vacuum-packed.
