MIM powder metallurgy injection molding technology not only includes iron-based, copper-based, stainless steel, alloys, titanium alloys and other materials, but also special ceramics, which can be made into various ceramic precision parts. For example, in the near-hot digital electronic mobile phone industry, many brands of high-end flagship mobile phones use ceramic back covers, ceramic watches and some biomedical porcelain sheets. These fields require the appearance and accuracy of ceramic parts. It promotes the research and development of ceramic powder metallurgy injection molding technology.

Key processes and technologies of MIM powder metallurgy injection ceramics:

1. Adhesive mixing technology.

The binder has good compatibility and shear dispersibility with ceramic powder, and the feedstock can have very good fluidity, so that ceramic compacts with high strength and good dimensional stability can be produced.

2. Injection molding control.

Key factors such as the rational design and processing of ceramic molds, the setting and optimization of injection parameters, and the exhaust and stress of the green body during the mold filling process will all have a great impact on product quality.

3. Degreasing technology.

You can choose thermal degreasing, or you can use solvent degreasing and catalytic degreasing, which are very efficient and stable degreasing technologies.

4. Avoid impurities.

In the key process of ceramic injection molding, iron or other impurities are not allowed during mixing, injection, and degreasing, which can cause contamination and damage to the product, affecting its appearance and quality.
