Product Description
Silicon Nitride Ceramic Weld Pin
Innovacera manufactures Silicon Nitride (Si3N4) Ceramic weld location and control pins for use in resistance welding. These are used in the metal forming industry to allow precise welding of nuts to sheet metal.
Due to ceramic's high hardness and durability, metal can't compete with it in insulating properties, resistance to temperature changes, and minimal wear. Another advantage of using ceramics as centering pins is their smooth polished surface, which prevents welding spatter from adhering. However, when welding pins made of commonly used zirconia ceramics, the service life does face a limit. This material also cannot withstand the currents in projection welding and the required 800°C operating temperature over time, so it wears out. And centering standard molds made of silicon nitride ceramic is a good choice.
Silicon nitride ceramic weld location pins have the following advantages:
1.High-temperature stability
2.Corrosion resistance
3.High hardness and wear resistance
4.High precision
1.High-temperature stability
2.Corrosion resistance
3.High hardness and wear resistance
4.High precision
