Ceramic Locating Pins Si3N4 Silicon Nitride Welding Guide Heat-Resistant And Non-Conductive Ceramic Pin
1 . Descriptions:
Silicon nitride is a man made compound synthesized through several different chemical reaction methods. Parts are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance.
High performance silicon nitride materials were developed for automotive engine wear parts, such as valves and cam followers and proven effective. The cost of the ceramic parts never dropped enough to make the ceramics feasible in engines and turbochargers. The very high quality bodies developed for these demanding high reliability applications are available today and can be used in many severe mechanical, thermal and wear applications.
Locating pins for Nut welding are produced with several different materials and several different coatings. Generally speaking, the more costly the pin, the “longer life” it has in production. As a long time distributor of resistance welding supplies, we stock commonly used pins at competitive prices.
Silicon Nitride Ceramic is typically used to make welding guide rolls for the high frequency ERW in continuous steel tube & aluminium tube production. Si3N4 is an excellent material solution in this application because of its following advantages:
|
· Flexural strength |
· Chemical resistance |
· Electrical insulation |
· Corrosion resistance |
· Dielectric strength |
|
· Wear resistance |
· Temperature resistance |
· Thermal conductivity |
· High voltage |
· Hardness |
Location And Resistance Weld Centering Pins
The heat-resistant and non-conductive ceramic pin materials help achieve consistency over hundreds of thousands or millions of welds, without the need for constant downtime and replacement.
The weld pins are available in three standard noses, for automatic feeders or hand-fed applications, with standard diameters to 0.1 mm stamping hole diameter.
