Description – What It Does
The Ultraflex R-75 is a 48″ sheet extrusion die engineered to transform molten thermoplastics into flat sheet with excellent gauge control and uniform melt distribution. By combining a flexible lip design with a patented internal restrictor bar, the die ensures consistent quality across the full sheet width.
It is designed for medium-thickness sheet extrusion and has been proven in applications requiring ¼″ sheet products.
Capabilities
Produces sheet up to 48″ wide
Adjustable lip gap: 0.050″ – 0.275″
Produces sheets up to ¼″ thick
Handles a wide range of thermoplastics, including PE, PP, PS, ABS, and PVC
Multi-zone heating maintains uniform melt temperature across the die width
Flexible upper lip allows quick adjustments to correct thickness variations
Restrictor bar design ensures even polymer distribution
Core Functions
Melt Distribution: Channels molten polymer evenly across the full 48″ width
Gauge Control: Lip adjustment enables precise sheet thickness settings
Flow Balancing: Internal restrictor bar equalizes flow, preventing thick/thin streaks
Sheet Formation: Produces flat, uniform sheet suitable for cooling rolls or downstream forming equipment
Design Features & Benefits
48″ Working Width: Ideal for medium-format sheet production in packaging and industrial markets
Ultraflex R-75 Design: Proven EDI technology trusted across the industry
Flexible Upper Lip: Fine-tunes thickness while running, reducing downtime
Replaceable Lower Lip: Extends die service life and adapts to material changes
Patented Restrictor Bar (US 3,859,032): External adjustment system for quick, precise balancing
Multi-Zone Heating: Promotes consistent melt temperature and sheet quality
Heavy-Duty Construction: Long-lasting tool steel die body for continuous operation
Applications & Industries
Packaging – thermoforming sheet for food trays, lids, clamshells, and disposable containers
Construction – protective panels, liners, and rigid sheet products
Automotive – ABS or polyolefin sheet for dashboards, trims, and panels
Industrial Manufacturing – flat stock for machining, forming, or lamination
General Plastics Processing – multi-purpose sheet extrusion for PE, PP, PS, PVC, ABS
Machine Overview & Summary
This EDI Ultraflex R-75 extrusion die offers a 48″ sheet width capacity, adjustable lip range from 0.050″ to 0.275″, and proven ability to produce ¼″ thick sheets. With its patented restrictor bar system and flexible lip design, it delivers excellent gauge control, uniform distribution, and high-quality sheet production.
The die includes multiple heater zones and thermocouple ports (condition of elements to be verified). Its replaceable lower lip and durable construction make it a rebuildable, long-term asset for any sheet extrusion line.
Condition: Used. Exterior wear present. Lip edges and heater elements should be inspected prior to use. Restrictor bar adjustment hardware intact.
