Zirconia

Overview

Zirconia

Zirconia (ZrO2) is used in various industrial field as a high-strength and wear-resistant material.
It can be used for components and decorative parts of the equipment as a high-strength structural material with the texture of the surface and abundant color variation.
Mold cast forming realize 3D and complicated shape without after additional machining process.

Mold cast forming technology

Mold cast forming technology

By hardening ceramic slurry in mold, ceramic products with complicated shape can be formed without after additional machining process.
Component with small and / or fine shape, long and / or complex shape, thin wall thickness shape can be formed. It is difficult to produce by press forming, injection molding and mechanical processing.
