I was just asked…

“We are confused on how to calculate the new shot size when we close off a cavity.  Our question is do we calculate shot size minus the Xfer point or do we calculate from the shot size to the cushion.”

 

My Response

Typically, you will maintain the transfer position, but reduce the shot size to ensure you have a first stage short shot. 

 

It is always best to repair the damaged cavity as soon as possible since a blocked cavity reduces productivity, creates imbalance, shift the temperature equilibrium, and introduces variability to the entire process.
