What is Ceramic Structural Parts
Ceramic structural parts are precision ceramic parts obtained by using high-purity special ceramic materials, through rigorous structural design and appropriate forming method, and processed.
Is it Good to Use Ceramic Structural Parts?
You can see the advantages of ceramic structural parts through the comparative table between ceramic, metal and polymer below.

Why do Metallization on the Surface of Ceramic Structural Parts?
Forming | Finishing | Metallization |
We will choose the most suitable forming method on the basis of saving costs and ensuring quality. | In order to achieve the precision of the product, most ceramic structural parts need further finishing treatment after the sintering process. | Metallization of ceramics refers to the creation of thin metal layers (films) on the surface of ceramics. After the surface of the ceramic material is metallized, it has both the characteristics of ceramics and the properties of metal. |
