Egan / Johnson, 60 Inch Sheet Extrusion Line, 1520mm Width, 4.5 Inch Extruder, 250 HP

Egan / Johnson, 60 Inch Sheet Extrusion Line, 1520mm Width, 4.5 Inch Extruder, 250 HP

Description

  1. Overview
    1. Custom extrusion line and auxiliaries representing a complete system for the precision manufacture of sheets and rolls.
    2. Can be configured for polyester, polystyrene or polypropylene.
    3. Specially prepared for high quality packaging materials and lenticular lens sheet production.
    4. Originally designed and built by Egan / Johnson for Eastman Kodak to be used with polystyrene resin for sheets of various thicknesses.
    5. During the period 1996, used for packaging material of polystyrene for Johnson and Johnson and lenticular lens sheets of Eastman Petg 6763 for Kodak’s own imaging usage.
    6. Lens quality was superior to any existing manufacturer.
    7. During the period 2004 to present, this line was completely overhauled and engineering improvements were designed and effected to increase performance and add feature functionality in both plastic extrusion and lenticular technologies.
    8. Modification of the polishing stack to improve better melt presentation at nip in addition to individual servo drives for the polishing stack and all pull rolls with dynamic tension control.
    9. Installation in close relation to the nip for improved performance of the Eurotherm beta gauge system.
    10. New 60 inch Cloeren auto-die.
    11. Design and construction of many new components including all new idling rolls in perfect alignment and balance, a large capacity web accumulator to assure temperature stabilization and reduce stress prior to sheeting or winding.
    12. Refurbishment of all line support equipment and auxiliaries to assure optimum productivity and cost efficiency with improved product quality.
  2. Extruder
    1. Johnson (Egan) Powerflight 4.5 inch 32d vented 250 hp extruder (vent currently plugged).
    2. Xaloy bimetal barrel (new 1998; only 280 tons production since new).
    3. Xaloy ‘efficient’ barrier screw for pet presently installed.
    4. Liquid internal cooled screw (first 4 flights) and liquid cooled barrel.
    5. Reliance 250 hp main motor (less than 1,500 hours since major overhaul).
    6. Reliance 250 hp dc drive (new in 1997; less than 1,500 total hours).
    7. Gearbox oil pump, oil cooled by heat exchanger.
    8. Comes with extra set of gears and bearings; current gearing 11:1 (150 rpm); additional set ratio 17:1 (100 rpm).
    9. Includes 4 pieces Egan heating/cooling elements.
    10. Controls for drive and temperature are not included, but available as a custom design/build project or via third party at our cost.
    11. Original documentation, drawings, and diagrams are included; Johnson/Egan/Eastman Kodak.

    2. One (1) single stage general purpose screw with mixer section (used for hips) in plywood crate on coasters, with drawing.
    3. One set screw pulling and cleaning equipment in plywood crate on coasters.
  4. Screen Changer
    1. Beringer 4.5 inch hydraulic screen exchanger with Reliance power pack and accumulator.
    2. Screws are pulled through screen exchanger.
    3. Spares for screen exchanger and hydraulic unit are included: 39 pieces 4.5 inch breaker plates for screen exchanger in wood storage crates, plus 300 pieces of 4.5 inch stainless steel screens.
    4. Documentation is included.
  5. Melt Pumps
    1. Two (2) Maag model 56/56 gear pumps with one 15 hp Reliance dc motor and Reliance drive plus one right angled gear reducer (worm and wheel).
    2. The two pumps are identical; both rebuilt by Maag in 2001, one has 500 hours since overhaul, the other unused in transport crate.
    3. Spare parts with pumps include one set of four (4) bearings, one main drive shaft with gear, two (2) visco seals and shaft sleeves.
    4. The pumps are oil heated for accurate heating; heater is incorporated with pump and motor stand.
    5. Original electric/electronic documentation and diagrams included; Johnson/Egan/Maag/Chromaloy/Eastman Kodak.
