Coextrusion feedblock EDI® Ultraflow™ V-T

Overview
The Ultraflow™ V-T is an adjustable-geometry coextrusion feedblock designed for dynamic control of layer distribution across applications from simple sheet to complex packaging films. It features adjustable combining planes where melt streams join the central flow channel, enabling on-the-fly layer-ratio changes and improved process flexibility.

Key capabilities

• Adjustable combining planes for dynamic layer-ratio changes without full shutdown
• Optional selector spools to preset layer sequences upstream of the combing point
• Profiling actuators with interchangeable profile bars for fine tuning of individual layers
• Controllable linear valves allowing precise on-the-fly layer ratio adjustments
• Compatibility with the EDI® Layer Multiplier system to multiply layers

Why choose an adjustable coextrusion feedblock?
Adjustable-geometry feedblocks enable quick product or structure changes with minimal impact on production. Unlike fixed-geometry feedblocks that require line stops to change layer ratios, the Ultraflow™ V-T permits rapid adjustments while the line remains running, reducing changeover time and increasing versatility.

Designed features and functions

• Selector spools to arrange layer sequences and optimize upstream flow patterns
• Large profiling actuators that can be positioned at the combination point or upstream to refine layer distribution
• Customizable extruder entrance locations to fit specific line layouts
• Ability to multiply layers when combined with EDI® Layer Multiplier equipment

Typical benefits

• Improved layer ratio stability through precise profiling and actuator control
• Increased uptime and reduced changeover time by enabling adjustments without full stop
• Enhanced end-product precision and repeatability via controllable linear valves and profiling systems
