[0002] When existing ceramic materials are used to make industrial parts, powder processing technology is usually used for processing. For example, after being made into a specific shape through a mold, it is sintered at high temperature and then processed again to obtain the desired structural parts.

On the one hand, it increases the difficulty of processing complex parts, and on the other hand, the accuracy between multiple matching parts cannot meet the requirements. Our technical team explores the characteristics of ceramics.
