Shot Blasting Measurement Kit

Surface Finishing Equipment Co. offers Shot Blasting Measurement Kit. Shot Blasting Measurement Kit is a simple technic to measure and control blast cleaning process and a better method of SPC Control is to use almen strip. In every shift, the strip is passed thruoug blast stream and its curvature is measured by almen gauge and recorded. The cirvature of strip is decided and standardized for job to job after controlling all the factors as mentioned above for containing statisfactory finish and output. Threafter in every shift one strip is passed to record the curvature reading with help of almen gauge and SPC chart is made. Normally the curvature of strip is affected by control cage wear, impeller wear, blade wear, the waer and tear of these parts will shift hot spot location and intesity. The cahnge in media quality will also have affect upon the curvature. The cleaning rate will also affect the curvature of strip. On the basis reading generated and recorded, the corrective measure is taken on the above mentioned factors. The sequence of event is listed as under:

• Mount the Almen strip onto the special holder.
• Mount the Almen holdeer and strip onto a dummy part.
• Pass the dummy part through the blast cleaning machine.
• Remove the alen strip from the holder.
• Measure the curvature ‘arc height’ of the strip.
• Record the value or plot the data onto the SPC chart.
• Repeat on a periodic basis (daily).
