Setting Final Cushion...
During some classroom training the other week, a student asked me the following question...
What value should you set the cushion at?
A good rule of thumb is 10% of the initial shot size. For example, if the overall shot size is 100mm, then the cushion should be about 10mm. This avoids pressure losses from too much material in front of the screw, yet provides enough room in front of the screw for normal variability.
