High Speed Chill Roll attachment type LCRHS-700 and LCRHS-900 For films down to 10 microns with a line speed up to 100 meter per minute.  This stack comprises of a main large 400 mm diameter chill roll which faces the die, followed by two rolls of 200 mm diameter. The large diameter chill roll enables a rapid cooling of the film, assisted by a vacuum box to enable instant contact of the melt to the chill roll surface without entrapment of air. The entire rolling stack is mounted on an individual heavy duty rigid frame, separated from the down stream unit but with common rail system.  The high speed chill roll unit is made for production of single as well as multilayer films with a line speed of up to 100 meter/minute.  For LCRHS-700 the width of rolling stack is 700 mm and it is suitable for production of films and sheets with a width up to around 650 mm. which after edge trimming will have a width of around 550 mm.  For LCHRS-900 the width of rolling stack is 900 mm and it is suitable for production of films and sheets with a width up to around 800 mm.

Heavy duty chill roll attachments. The roll width for LCR-300-HD is 350 mm and can produce films or sheets with a width of up, to 300 mm. For the larger LCR-350-HD, the roll widths are 400 mm and the film or sheet width is here up to 350 mm.  All 3 rolls in the rolling stack have a diameter of 145 mm and they are all cored with internal chamber for water cooling and heating. The rolls can also be connected to oil heating units for high temperature applications.

Vertical machine direction stretching unit MDO, our MDO unit is a standalone stretching unit that for your convenience can be placed either ‘in-line’ or ‘off-line’ to a cast film or blown film extrusion line. It will stretch both single and multi-layer films to a maximum stretching rate of 10 times (depending on material). The MDO unit has 3 different setups available.  ‘In-line’ with a multi-layer cast film line, ‘In-line’ with a multi-layer blown film line, and ‘Off-line’ as a stand alone unit.  The MDO unit is supplied complete with 4 hot oil roll tempering units and all rolls are independently driven by designated servo motors with speed controls on the LCD touch screen.

The roll width for LCR-300-HD is 350 mm and can produce films or sheets with a width of up, to 300 mm. For the larger LCR-350-HD, the roll widths are 400 mm and the film or sheet width is here up to 350 mm.  All 3 rolls in the rolling stack have a diameter of 145 mm and they are all cored with internal chamber for water cooling and heating. The rolls can also be connected to oil heating units for high temperature applications.  The rolls are made of high grade tool steel of same high quality as we use for our two-roll mills. They are hardened and precision ground after which they are equipped with a hard chrome layer which again is precision ground and polished to a mirror surface.  The whole rolling stack assembly can be positioned either vertically or horizontally.

Compact chill roll film and sheet extrusion line comprised of our Laboratory bench top single screw extruder Type LBE20-30/P for general extrusion of PE, PP, PS, ABS etc.  Non-vented type equipped screw and barrel in high-grade nitride steel, screw diameter 20 mm and L/D ratio of 30.  One unit Chill roll sheet/film attachment with flat film die allowing for 100 mm wide opening and adjustable lips for film and sheet thickness from 0.3 to 2.0 mm.  Sheet and film chill roll attachment for horizontal extruder die connection. With large 145 mm diameter chill roll and additional cooling and polishing rolls. All 3 rolls are equipped with rotary joints and cored inside for cooling/heating water, which enables efficient temperature control of roll surface.

Our New Scientific Mini Single-Layer Film and Sheet Line Type LMCR–150 is a viable low-cost alternative to our regular cast film lines. It has a mini-size extruder connected to a single-layer cast film die, and it is equipped with a vertically adjustable chill roll with a diameter of 145 mm and a width of 150 mm. This single-layer mini cast film can process PE, PP, PA6, PC, PET, EVOH, PLA, PS, ABS, and many other resin types.

THE LINE FEATURES:

• Mini design taking up a floor space of only 1.5 m x 0.7 m (5.0 x 2.3 ft) and a height of 1.2 m (4.0 ft) make it easy to fit into even the most crowded lab.
• The Mini Extruder can process regular polymer pellets
• The entire assembly is mounted on a sturdy steel subcabinet containing all major supply cables and electric components inside the subcabinet, giving a very clean appearance with very few visible connections to the extruder.
• The mini single-screw extruder is mounted on an elevated base on top of the subcabinet
• The die and the extruder are mounted individually on the same sliding rail, and the die can be separated from the extruder with a quick lock C-clamp. This enables easy removal of the extruder for cleaning and removing of the screw.
• The roll is vertically adjustable so that the gap between the die and the roll can be adjusted to reduce the necking of the extruded melt from the die.
• The rubber pressing roll of the chill roll has a handle that can be swung and securely locked into place away from or towards the roller. In the position where it presses against the chill roll, it serves to ensure that the film is tightly wrapped around the Chill Roll for optimum cooling efficiency. The pressure of this rubber pressing roll is adjustable with a spring-loaded screw
• The film tensioning nip is opened with a handle, and the nip force is adjustable with a spring-loaded screw
• The surface wind-up unit can hold a max film width of 125 mm, and it is equipped with an air expansion shaft holding a 3-inch bobbin
• The chill roll, haul-off nip-roll, and wind-up device are driven by three individual AC servo motors
• The line is equipped with a user-friendly 7-inch full central LCD touch screen unit controlling all functions like:
• extruder temperature and RPM
• die temperature
• chill roll temperature and RPM
• downstream nip-roll and wind-up RPM
