1．Powder quality control:

The component content and purity

Surface area

Particle size

Powder trial production (only passed test,will the powder
can be applied for next production)

2．Forming sintering control:

Producing as per each powder lot number

Trial firing is required for finished trial production

Testing trial firing product (density,crushing strength,wear loss)

Sampling inspection for density of every lot powder in the process of sintering

3． Screening control:

Screening in the process

Screening finished products
