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.
Mingrui Ceramic 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 °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.
