Industry Customized Steatite / Alumina Ceramic Shell for KSD Thermal Switch
Description of ceramic insulating base for KSD thermostat
Thermal switch / Thermostat is a key component in a variety of home electrical appliances, electric motor and cooling devices, Due to the special working conditions, it requires all parts of the thermal switch with high insulation resistance and high-temperature resistance and so on. The technical ceramic could offer dielectric strength, high insulation resistance, excellent thermal properties, super mechanical strength, and great chemical stability. Considering the cost is another critical factor in the thermal switch, so alumina, steatite, and low alkali ceramics as the mainstream material for ceramic parts of thermostats.
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.

Application :
These ceramic pins are widely used in a variety of KST adjustable bimetal thermostats, steam iron thermostats. temperature control switch.
Packaging proposal:
1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other, to avoid any cause any chippings during transportation.
2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
