Feb 25, 2017 · Some molders go with the biggest screw possible, but do not do this, as it will cost you more money long term. Super-small shot sizes, using less than 20% of the barrel capacity, often lead to long residence times, which in turn lead to polymer degradation and poor process control. Plus, big screws usually mean lower plastic pressure capability.
