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.

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.
