Process technology

As structural components, most industrial ceramics require precision machining, especially those with complex shapes and high precision requirements. Due to shrinkage and deformation of the ceramics during sintering, it needs to be precision machined as dimension tolerance and surface finish are difficult to meet requirements after that. In addition to achieving dimension accuracy and improving surface finish, it can also eliminate surface defects. Therefore, precision machining of ceramics is an indispensable and critical process.
