Home Forums General Discussion Shot Peening Process, Intensity, Coverage Conditioning New Cast Steel Shot

Gary,

I agree with Lennart with regard to the pre-conditioning of new shot prior to use as a best practice. Also, I would suggest that when adding shot to your machine you never add more than 30% of the total hopper capacity. Be sure to add it slowly, mixing it in with the shot already in the machine. You state that you cannot adjust any of the parameters that affect intensity. Don't you have a tolerance range for your air pressure and shot flow? You are permitted to adjust your target point in a frozen process as long as you don't violate the limits. You should be able to adjust within your tolerance band to mitigate a slight rise of .0015". A combination of less air pressure and an increase in shot flow should do the trick. Of course you must run a new 4 point saturation curve to verify you are incompliance.
