2. Tolerance: Diameter with tolerance 0.001mm, length with a tolerance of 0.01mm
3. Material options: YSZ zirconia, TTZ zirconia, 99~99.7% alumina, Silicon carbide (SiC)
4. Forming method: Dry pressed, Hot pressed, Ceramic injection molding and so on
Description of zirconia ceramic positioning pin:
With excellent mechanical strength and toughness, people call zirconia as "ceramic steel" in the technical ceramic filed. Furthermore, zirconia offers superb high hardness, excellent thermal shock resistance, high-temperature properties, and low thermal conductivity, due to these outstanding properties, zirconia is considered as an ideal raw material of ceramic positioning pin.
As zirconia ceramic has a superb resistant crack, so it's easier to do high precision processing for the zirconia ceramic part, then get a very high accuracy dimension.
The material of welding technology is usually used in any extreme environment, should be chosen according to the different applications, to meet its high wear resistance, high durability, high-efficiency requirements.

Manufacturing flow chart of ceramic pin
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 and transportation solutions
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.
