Show / Hide DescriptionAccufly
ESI's Accufly® in-line cutting system offers innovative technology with high accuracy cutting by incorporating a servo driven stop/go feeder with fiber optics for cut-to-length signaling. Length is set by adjusting the fiber optic bridge assembly, or utilizing the servo feedback from the feeder motor. Just prior to the set length being reached, the feeder belts ramp down to ensure proper cut length positioning without overshoot. When the fiber optic beam is broken, the feeder belts stop and the servo driven flyknife is cycled, resulting in a square cut and high accuracy cut length. Because the feeder is maintaining a loop ahead of the Accufly, the product is fed without ...
Cut-and-Transfer coiler
ESI Cut-and-transfer coilers automatically cut the extrudate to length, index coiling stations and start the next coil without operator intervention. This can greatly reduce labor by allowing the operator to be assigned additional tasks, instead of waiting for the reel to complete. On high speed extrusion lines or lines which run short length coils it is often necessary to allocate an operator exclusively to the coiling station to change reels. The time taken to manually change reels often results in a significant length of extrudate being accumulated during the changeover causing extrudate to pile up on the floor and the operator to run the coiler at a very high speed to catch up.
ASC (Advanced Servo Control) Puller-Cutter
ESI's dual servo puller-cutters are designed to meet a wide range of in-line flycutting of plastic and rubber tubings and profiles. Precision in-line cutting of extruded profiles and tubing requires the extrudate to be presented to the cutter at a consistent rate. Our dual servo puller-cutter unit includes a fully programmable motion controller, color touchscreen, servomotors for both puller & cutter. System offers a cut length accuracy of +/- .010" with electronic camming of blade motion to achieve peak blade speed at any cut rate up to 1000 cuts per minute and a continuous cut mode of up to 1800 cuts-per-minute.
Airfly Cutter
The patented Airfly cutting head was designed as a simple, efficient cutting device with very few moving parts for low maintenance. The Airfly is an 'on-demand' pneumatically powered flyknife cutter can be furnished as a 'table top' unit with basic controls. It is powered by multiple stainless steel air cylinders, and does not require the use of an electric or vacuum/clutch brake, has no linings to wear or replace, needs no electric motors or over-excitation circuits, and operates without the need for timing drums and belts. The Airfly is available in a standard 3.5" bushing size.
Flood Tanks
ESI's flood tanks are designed for immersion cooling of rubber and plastic tubing and profiles and are available in a wide variety of standard cross sections and lengths.
Panners
ESI Panners are frequently utilized in the rubber industry for automatically winding product in a ‘lay flat’ condition onto a pan (e.g. uncured rubber tube or hose). Extrudate can be taken from the panner and cured in an autoclave or stored for later application of reinforcement. Panners can be single station or dual station with automatic transfer between the pans. Machines are typically servo controlled and consists of a driven lead-in conveyor, a driven support turntable and a traverse mechanism to move the turntable laterally. Pan rotational speed and pan lateral position are automatically adjusted to lay the product in spirals with preset gap between the extrudates.
Servo Puller-Cutter
ESI's servo puller-cutters are designed to meet a wide range of in-line flycutting of plastic and rubber tubings and profiles. Precision in-line cutting of extruded profiles and tubing requires the extrudate to be presented to the cutter at a consistent rate. ESI puller with integrated servo cutter unit offers a cut length accuracy of +/- .030" with an on-demand 400 cuts-per-minute capability. Units are available with larger servomotors for increased cutting torque, cutter head slide adjustments, larger diameter bushings, blade lubrication and fully caged puller assemblies.
Multi-Pass Cooling Tank
When you are limited on floor space for your cooling needs, just look to ESI's Multi-Pass cooling tanks to solve your problem. With our Multi-Pass cooling tank, your flexible plastic or rubber profile can be wrapped several times around our custom capstan rollers to eliminate the need for longer or multiple spray tanks.
Let-Offs
Powered Let-Offs are designed to unwind profile from coiled reels. They are typically utilized on crosshead extrusion lines and can be used for letting off metal reinforcement (e.g. automotive seal lines) or extruded tubes with or without reinforcement (e.g. hose lines). Let-offs are often supplied in conjunction with accumulators to ensure continuous supply of material to the extrusion line. Let-offs can also be used for transfer of bulk coiled extrudate to smaller consumer sized packages. Let-offs are typically dancer controlled to adjust reel speed as effective reel diameter changes and can be designed as single station or dual station. Machines are designed for a ...
Cooling Drums
ESI cooling drums are designed for efficient in-line cooling of both sides of sheet or round extrudates. Drum systems can consist of two or more drums in either a vertical or horizontal configuration.
For sheet products the drums are typically chilled for cooling and the sheet is not exposed directly to water. For round products the extrudate makes multiple wraps around the drums. The cooling is typically achieved by submerging the bottom of the lower drum in water or by spraying the ...
