High Insulation Technical Al2O3 Alumina Ceramic Housing for Bimetal Thermostat
The main characteristics of ceramic parts for thermostats
1. Good thermal shock, it can withstand the thermal shock around 200 ºC
2. High mechanical strength, the hardness over than 1500Mpa
3. High insulation resistance, the insulation strength up to 18KV/mm.
4. Heat resistance, the working temperature can up to 1500ºC
5. Corrosion resistance, it will not react with most of strong acid and alkali
6. Quality surface free of any cracks, burrs, impurities, pinholes and so on
7. Cost-effective depend on fully automatic machines and veteran operators
8. Many selections of sizes with ready molds, provide quick and flexible delivery
The specification of the ceramic parts for thermostats
1. Available material: steatite, alumina, low alkali ceramic
2. Shaping methods: Hot pressed, dry pressed via automatic mold
3. Types of ceramic bases: a various different design for KSD301, KSD302
4. Size: out diameter and length as per physical specification or drawing
5. Secondary process: vibrating polish, centerless grinding, and so on.
The description of ceramic parts for thermostat
Ceramic parts for iron/steam/oven KST adjustable bimetal thermostat are made of alumina, steatite, or low alkali ceramics. All these materials offer high insulation resistance, dielectric strength, 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. All ceramic insulating parts we supplied are free of crack, burr, pinholes, impurities, with a dense, smooth surface.
Whatever, it's prototyping case or high volume production need, we are able to meet you completely.

Our capability and strength
We have in-housing comprehensive manufacturing types of equipment, including forming, sintering, CNC machining, precision grinding, laser cutting, and so on, it helps us to control the quality very well, also it greatly benefits cost control.
Packaging proposal for ceramic parts
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.
