95 Porcelain Special Purpose Wear-Resistant Ceramic Positioning Pin
Special-shaped ceramic positioning pins have extremely strong corrosion resistance, and can also be used in strong acids, strong alkalis, and seawater. At 1100 ℃, the strength and hardness are almost unchanged. Can also be used in non-magnetic and magnetic fields.
Performance characteristics:
The ceramic positioning pin is similar to the ordinary welding
positioning pin, but it is made of super-hard silicon nitride
ceramic material. The special physical and chemical properties of
ceramic materials determine certain special properties of silicon
nitride positioning pins. For example, high wear resistance, high
hardness, non-conductive, non-magnetic, non-stick welding slag and
other excellent properties.

Ceramic positioning pins can be applied to accessories for special
purpose parts of high temperature resistance, corrosion resistance,
wear resistance, and high voltage resistance used in industries
such as electronics, machinery, chemical industry, metallurgy,
textiles, and power.
After the positioning pin is worn, it will produce a blocking
effect when loading and unloading, causing the positioning hole of
the part to be hooked. In order to ensure the accuracy of the
relative position between the two parts after the certificate is
installed, cylindrical pins or tapered pins are often used for
positioning, so the requirements for the pins and pin holes are
high. In order to facilitate the processing of pin holes and pins,
as far as possible, the pin holes are made as through holes as much
as possible.
All kinds of positioning pins, porcelain tubes, porcelain rods and electrical ceramics can be customized and processed with samples.
