Alumina Ceramic bolt

1.Powder preparation is crucial for manufacturing an alumina ceramic bolt.

Whether you are making it for an alumina ceramic bolt or other products, different molding processes are also consider. The powder particle size is below 1μm micron. If the manufacture of high-purity wear-resistant alumina ceramic requires the purity of alumina to be 99.99%, it is necessary to crush ultrafine.

2.Molding method

The forming methods of wear-resistant alumina ceramic include dry pressing, grouting and extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing, and other methods. The molding method can greatly affect how effectively an alumina ceramic bolt shape. In recent years, domestic and foreign molding methods have developed such as filter press molding, direct solidification injection molding, gel injection molding, centrifugal grouting molding, and solid-free molding. Different product shapes, sizes, complex shapes, and precision products require different molding methods.

The technical method of densifying the granular ceramic green body to form a solid material calls sintering. Sintering removes the voids between the particles in the green body. It also removes a small amount of gas and impurity organic matter. In addition, the particles can grow and combine with each other to form new substances.

4.Finishing and packaging process

Some materials need to finish after sintering. For example, products used as artificial bone require a high surface finish. A mirror-like finish increases lubricity. Due to the high hardness of alumina ceramic materials, wear plates need to finish with harder grinding and polishing brick materials. Examples include SiC, B4C, or diamond diamonds.
