Extrusion: Auto Die for Coating Applications
Equipped with a motorized internal and external deckling system for safe and easy operation.
Davis-Standard has introduced it next generation 510A die for
extrusion coating applications. Engineered with an innovative short lip design and edge-bead functionality, it builds on earlier generation Davis-Standard die offerings. Improvements include simplification of the die’s pre-land channel and internal deckling blade for easier cleaning and maintenance.
The die is equipped with a motorized internal and external deckling system for safe and easy operation. The internal die channel is optimized for melt flow and deckling adjustment for precision edge-bead control. According to company officials, during testing the die has shown minimal or no edge trim while eliminating high edges.
The 510A die is said to be ideal for acid co-polymers, LDPE, LLPE, HDPE and PP resins among others for extrusion coating and lamination onto board, alumimum foil and for flexible-packing applications.
A troubleshooting timeline is essential to help you quickly identify problems and their causes. Here we'll describe such a timeline and how to use it to solve one common problem—melt fracture in tube and profile extrusion.
Just like selecting the extruder size and drive combination, the L/D should be carefully evaluated.
And as with all sciences, there are fundamentals that must be considered to do color right. Here’s a helpful start.
