Ceramic insulating pins for adjustable bimetal thermostats are made of alumina, steatite or low alkali ceramics. All these materials possess dielectric strength, high insulation resistance, excellent thermal properties, super mechanical strength, and great chemical stability during high-temperature working conditions.
We have been manufacturing lots of thermostat ceramics for bimetal thermostats, Iron thermostats or capillary thermostats for 15 years, including ceramic insulating pins, ceramic insulating rings, ceramic insulating bush, ceramic insulating spacer, ceramic insulating base, ceramic insulating holder and so on. All of them are with a selection of specifications with our own molds, also we support customized ceramic parts for various adjustable bimetal thermostats.
Whatever, it's prototyping case or high volume production need, we are able to meet you completely.
