Full-ceramic pins have much lower thermal conductivity than hard-metal pins Superior abrasion resistance compared to hard metal pins, with higher tensile strength and higher max operating temperatures Treated properly, full-ceramic pins last much longer than other pin materials
ceramic weld pin is a standard shape and size for projection welding applications. Ceramic pins provide high durability and reliability at a much lower cost than full ceramic pins, and are less prone to shattering after being mishandled or dropped. Ceramic-coated pins are more durable and cost-effective than anodized steel or KCF, and do not require heat treatment before use.

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.
Now we 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 °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.
