How do we control the quality of machining

In production, we demand not only quantity but also quality.

How do we ensure finished product quality (FQC inspection)

1. Visual Inspection

2. Material Grade Measurement

3. Dimension Inspection

4. Roughness Detection

5. Roughness Detection

6. Leakage Test

Rotary valve is often used in blinding.
Rotary valve is applied to discharge powder or granular material either in positive air pressure or in negative air pressure of pneumatic conveying system.Also it is a necessary device for ventilation and move dust systems.Rotary valve is especially suitable for separating and discharging powder and small particulate matter in the process of positive and negative suction.
Rotary airlock feeders have wide application in industry wherever dry free-flowing powers,granules,crystals,or pellets are used. Rotary valve is primarily used for dischang of bulk soild material from hoppers/bins,receivers,and cyclones into a pressure or vacuum-driven pneumatic conveying system. Rotors have large vanes cast or welded on and are typically driven by small internal combusyion enginesor electric motors.
