spray drying

In a fully enclosed environment, the wet abrasive slurry is spray-dried to obtain particle size under the protection of high-purity nitrogen;

Features: low oxygen content, high purity, low swearing rate;

Advantages: uniform pressing density, precise size control, and small fluctuation of single weight.

CIP processing

At room temperature, use rubber or plastic as a covering mold, use liquid as pressure medium, and form powder material under high pressure;

Features: to prevent internal defects of pressed products;

Advantages: compacts of uniform density provide good assurance.

HIP processing

In an inert gas environment, the cemented carbide is subjected to high temperature and high pressure treatment;

Features: The internal pores are effectively eliminated and the microstructure is improved;

Advantages: Obtain densified, high-hardness, high-strength materials.

stress treatment

Cryogenic treatment: The cemented carbide is treated at a process temperature of -196掳C; Features: Internal stress is eliminated and microstructure is improved; Advantages: Effectively improve overall performance and significantly increase service life.

Vibration treatment: The cemented carbide is treated at the required vibration frequency of the process; Features: Internal stress is eliminated; Advantages: The service life is significantly improved.

Heat treatment: The cemented carbide is heat treated under the requirements of the sintering furnace process; Features: Internal stress is eliminated; Advantages: The service life is significantly improved.
