Black silicon nitride ceramic locating pins
Alias: spot-welding machine ceramic locating pins / welding-use ceramic locating spare parts
Description：
Ceramic locating pins made of black silicon nitride (Si3N4) material are often used as locating fittings in the welding process. Silicon nitride is a high-performance ceramic material with excellent mechanical properties, high temperature resistance, and excellent thermal shock stability and wear resistance. This makes it ideal for use in extreme environments such as high-temperature welding operations.
The design of the locating pin, which includes a cylindrical body and a conical shape or spherical top, this shape helps ensure precise locating and support of the weld material in the spot-welding machine, and it is easily installed into the corresponding mechanical device.
Material Properties
Silicon nitride offers extremely high mechanical strength (modulus of elasticity of 290 GPA) and excellent high temperature resistance (up to 1200℃), making it suitable for demanding industrial environments. Its Vickers hardness is up to 1500 HV and its compressive strength is 2500 MPa, ensuring stability and durability under high loads and temperatures.
Product Features:
Silicon nitride locating pin customization, also known as spot welding machine ceramic locating pin, is a key component designed for high-performance spot-welding machines, with the following notable design features:
1. Structural design
The locating pin has a cylindrical body and a conical or spherical head, this special shape design helps to precisely position and support the welding material in spot welders, improves the positioning accuracy of components during assembly, especially in applications where quick and easy installation is required, such as automated production lines. Its conical or spherical head provides a better contact point, ensuring that the welded material is stable during machining.
2. Chemical stability and low surface friction
The black finish, which not only enhances chemical stability, but also reduces surface friction, which is essential for maintaining weld quality and reducing light reflections.
3. Excellent high temperature resistance
The locating pin is made of silicon nitride material through a high-temperature sintering process, which can work stably at temperatures up to 1200°C, which is very suitable for high-temperature welding operations.
4. Excellent thermal shock stability and wear resistance
The high thermal shock stability (△T℃ of 500) and excellent wear resistance enable the locating pin to maintain good performance under repeated thermal cycling and mechanical stress.
