Product/Mold Description

What are the main causes of die drool on plastic extrusion dies?
Die drool and other die flow irregularities are most often caused by internal
die surfaces that are scratched or pitted, or that have poor plating quality.
What are your ideas for optimizing sleeving applications?
For sleeving applications, you want to establish the correct drawdown
ratio and draw ratio balance for the material being extruded. Next, you
want to have a land that is appropriate for the die gap. For pressure
extrusion, you need an opening that is sufficient for the core to pass
through, but not large enough to allow leaking inside the tip.
Generally speaking, sleeving tooling improves wall thickness control,
and pressure tooling is better for faster line speeds.
