Ceramics Positioning Pin


ISO9001 Wear Resistant Ceramics


99 porcelain wear-compression resistant ceramic positioning pin


Product Overview

Positioning pins are most widely used in molds. Including stamping molds, injection molds and so on. Their precision is particularly high, and if it is only fixed by bolts, it will definitely not work, so only positioning pins are used to achieve positioning

Alumina has a high hardness and density, with an Inch hardness of 9, which is slightly lower than diamond. The bulk density is generally greater than 3.5 g/cm³, and some can reach 4.0g/cm³. Alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to different Al2O3 content. Among them, 99 alumina ceramic materials are used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings and ceramic seals. Parts, etc.; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts.

Widely used in coal-fired power plants, iron and steel, smelting, machinery, coal, mining, chemical, cement, port and terminal enterprises, coal transportation, conveying system, powder milling system, ash discharge, dust removal system and other large wear and tear mechanical equipment , Can provide different types of products according to different needs

• Extended service life


The ceramic positioning pin has extremely strong corrosion resistance, and can also be used in strong acid, strong alkali and sea water. At 1100 ℃, the strength and hardness are almost unchanged. Can also be used in non-magnetic and magnetic fields. Electrical insulation. The density is 3.25---3.28g/cm3, light weight, about 60% lighter than the steel ball, which greatly reduces the centrifugal force on the channel when the bearing rotates at high speed and reduces wear. High rigidity, high strength, its hardness is twice as high as bearing steel, and the elastic modulus is about 1/3 higher. The coefficient of linear expansion is 3.2×10-6/K, which is almost 1/4 of the bearing steel, and can withstand the rapid changes in temperature.


  • Shipbuilding, bridges, large-scale structural facilities
  • Lighting industry
  • Electronics and electric heating industry

With the development of science and technology and the improvement of manufacturing technology, new varieties continue to appear, and they will be used more and more in the fields of modern industry and modern science.
