High Hardness And Wear-Resistant Ceramic Positioning Pin Ceramic
Electronic Accessories
Product Overview
According to our understanding, the role of positioning pins is to
limit the free movement of items. Compared with traditional
material positioning pins, the advanced ceramic materials used by
the company occupy a greater advantage, such as zirconia ceramic
positioning pins, alumina ceramic positioning pins, silicon nitride
positioning pins.
There are 5 types of positioning pins:
1. Fixed positioning pins
2. Interchangeable positioning pins
3. Cone positioning pin
4. Cutting edge positioning pin
5. Standard diamond positioning pin
