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
