Burns are horrible, I hope he is able to keep full use of his hand.Couple months ago while I was off , one of our extruder's transition pipes went cold and polymer solidifed . The pressure inside is well over 2500 psi . One of our top mechanics of 30+ years took the call . He , as we all do , turn the band heaters up to 650 degrees from 550 and take a torch and map gas to heat the pipe up . He did , but unfortunately he was in the line of fire when the poly melted . He is black , but now has a white hand as it took all the skin off . EHS said we can't use this method any longer , but there is no other method . He was most likely being rushed to get the line up and took his mind off of what he was doing .
When you remelt the plastic are you able to start at the open end or do you have to get the entire slug hot enough to splat out?
