The most common coated pin we sell is a very hard ceramic coated steel pin. We can also supply pins coated with other materials such as black oxide and nitride upon request.
CVD Coated Pins and Sleeves
CVD pins are a D2 steel pin layered with a very hard ceramic coating using chemical vapour deposition technology. This coating is very hard and is non-conductive, so the pins are not only insulated from the electrical circuit, but also protected from wear and damage.
CVD pins area a very popular and cost-effective solution for any weld head system that requires the pin to be insulated, and as such, standard pins are often carried in stock. In addition, CVD sleeves can be incorporated into weld heads or special designs.
If you are looking for even better performance, we recommend using solid ceramic pins.
We can quote from samples, standard part numbers, and/or from prints/drawings. Please contact us using our online form.
