Extend the Life of Your Sandcarving Nozzle
To extend the life of your sandcarving nozzle, get into the habit of rotating your sandcarving nozzle a quarter-turn once a day or every two hours pending the volume of blasting per day. Not only will a worn sandcarving nozzle use more compressed air, but the abrasive will impact the substrate more aggressively and increase the potential for damaging the masking, or photoresist, material. As the volume of air and abrasive increases, it will create additional wear on the blast hose. It's ideal to replace the nozzle after it has worn 1/32".
