Si3N4 Silicon Nitride Welding Guide Ceramic Locating Pins Heat Resistant And Non Conductive Ceramic Pin

Ceramic Locating Pins Si3N4 Silicon Nitride Welding Guide Heat-Resistant And Non-Conductive Ceramic Pin

1 . Descriptions:

Ceramic pin can generally divided into the following:welding pin, guide pin,positioning pin,optical fiber connector ferrule and ceramic pin gauge,the common used material is zirconia ceramic,silicon notride ceramic and silicon carbide.
Us uses several lines of ceramic materials, to meet the needs of different applications, from resistance and MIG/TIG welding tooling to general metalforming and handling.
The common forming method of insert core is Ceramic Injection Molding (CIM). Optical fiber connector is an indispensable passive device in optical fiber communication system.
The ceramic pin is a high precision product with a tolerance requirement of +/- 0.001 to mm.

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:

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.

2 . Advantages

The automobile industry is keeping up with innovation by utilizing advanced technical ceramics to generate performance-improving changes in its production processes. High-Performance Ceramics are used to make pins that are used for positioning and welding by well-known automakers.
