High Precision Customized Ceramic Zirconia Threaded Rods

High Precision Customized Ceramic Zirconia Threaded Rods

Nowadays, more and more places are using ceramic rods, and some even require machining of ceramic rods. A threaded ceramic rod is a type of rod with a fixed function, which can be formed by injection molding or made by CNC machining. Ceramic rods produced by injection molding have the characteristics of low price and large output, while ceramic rods produced by mechanical processing have better accuracy and can match other components more smoothly.

Zirconia ceramics, as the main material of ceramic rods, have better surface roughness and can also function as self-lubricating during use.

Zirconia ceramics are a new type of advanced technical ceramics, mainly divided into three types of magnesium-stabilized zirconia ceramics, cerium-stabilized zirconia and yttrium-stabilized zirconia. All three kinds of zirconia ceramics have excellent physical and chemical properties. They have not only become research hotspots in the field of scientific research, but also have been widely used in industrial production. They are important raw materials for refractory materials, high-temperature structural materials and electronic materials.
