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.
Synthetic paper based on filled polyethylene or polypropylene film has been around for decades without causing much excitement--until recently.
A poorly designed profile die—one that does not permit the part to be extruded with the same dimensions from run to run—coupled with a lack of understanding of the extrusion process, is a recipe for scrap generation.
Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process.
