Description of ceramic insulating rings:
Our factory produces numerous ceramic components for the steam iron
bimetal type thermostat. They are made of alumina, steatite or low
alkali ceramics. All the materials we used are famous for their
high insulation resistance, dielectric strength, excellent thermal
properties, and super mechanical strength.
Besides ceramic insulating rings, we also manufacture ceramic insulating pins, ceramic insulating bushes, ceramic
insulating spacers, ceramic insulating bases, ceramic insulating
holders and so on. All of them are with a selection of
specifications with our own molds, additionally, we support
customized ceramic parts for various adjustable bimetal
thermostats. All ceramic insulating pins 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.

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.
