Why Choose KCF Ceramic Locating Pins?
1. Excellent Electrical Insulation

KCF ceramic is an electrically insulating material, making it particularly suitable for locating components positioned close to the welding current path.

Unlike conventional metal locating pins, the ceramic pin does not readily conduct welding current, helping reduce unwanted current paths and electrical interference during resistance welding.

2. High Heat Resistance

During nut projection welding and resistance welding, locating pins can be exposed to repeated heat generated by the welding process.

KCF ceramic provides excellent resistance to elevated temperatures and thermal exposure, helping maintain stable positioning performance during repeated welding cycles.

3. Resistance to Welding Spatter

Welding spatter can accumulate on conventional metal locating pins and gradually interfere with workpiece positioning.

The ceramic surface of a KCF locating pin helps reduce welding spatter adhesion, making the pin easier to maintain and helping extend its usable service life.

4. Good Wear Resistance

Locating pins are repeatedly inserted into and removed from positioning holes during automated production. KCF ceramic provides good wear resistance, helping maintain the original geometry and positioning accuracy over repeated production cycles.

5. Suitable for Automated Welding

KCF locating pins are suitable for automated and robotic welding fixtures where stable positioning, electrical insulation, and resistance to welding heat are required.

Applications

KCF ceramic locating pins can be used for:

Nut projection welding
Resistance welding
Weld nut positioning
Sheet-metal positioning
Automotive body welding
Automotive component welding
EV manufacturing
Robotic welding fixtures
Automated welding lines
Welding fixture tooling
Metal stamping and welding assemblies

They are particularly suitable for automotive body-in-white (BIW) and other high-volume manufacturing applications where locating components are exposed to repeated welding cycles.
