Black Si3n4 Silicon Nitride Ceramic Guide Pin For Projection Welding

With immense experience of the domain, we are instrumental in exporting, manufacturing and supplying an excellent quality spectrum of Si3N4 Silicon Nitride Ceramic Guide Pin in Xiamen, Fujian, China. Typically, locating pins are used for controlled, fine tolerance positioning of a work piece. For example, a pallet that is moved along one axis, where the drive mechanism is not accurate and stable enough to place it in a position sufficiently accurate to execute a particular process, the use of locating pins may be the best solution. Usually two locating pins are enough to properly locate the work piece on one plane.

UNIPRETEC now offers a full line of standard and custom-made ceramic locating and welding pins. Advanced ceramics, which ensure a perfect fit for sheet metal and nuts and are subjected to temperatures of up to 600 A c, have long replaced metal in the production of welding pins. Metal cannot compete with ceramics with regard to insulating properties, resistance to temperature change, and minimal wear and tear due to the high degree of hardness and durability. Yet another advantage of ceramics is their smooth polished surface, which prevents welding spatter from adhering.
