Breyer Extrusion

Extrusion Lines for EVA Films

CellProtect Lines 

The convincing extrusion technology for the production of low shrinkage solar encapsulant film for PV-modules.


BREYER offers the complete line including proven recipe and service:
Dosing system, extruder, die, process unit for forming, cooling, ­embossing & winding.

The BREYER CellProtect system allows much higher speed and therefore higher output compared with conventional systems. Since standard extrusion systems only provide a limited line speed/output, BREYER has developed a forward-looking system for a profitable production of low - shrinkage solar encapsulation film.

Extruders

Created with Sketch.

One of the core components of every extrusion line is and remains the extruder itself. From the start, BREYER relies on quality and sophisticated technology.

BREYER extruders are single-screw machines with high efficiency. Most thermoplastics are processed. The extruders are available in the following sizes: 30, 35, 45, 60, 75, 90, 105, 120, 150, 180, 200, 250 mm screw diameter.

The discharge capacity is depending on the size up to 2000 kg / h.

Our specialty is extruders with vacuum degassing . These extruders work particularly economically, since the energieaufwenige pre-drying of the granules omitted. By separating the remaining monomers, the quality of the melt and thus of the end product is increased. The extruders also have a high specific output. The machines also work reliably in the ejection areas, where other manufacturers must already be dried.


Energy savings
BREYER extruders are designed in such a way that they require very little energy during operation.


The control cabinets are equipped with a Siemens control as standard. The operation is conveniently carried out on the color display. Equipped with solid state relays, single current measurement for each zone, durable ceramic heating tapes (with fast connection plug-in connection), safety temperature monitoring and detailed error analysis.


Three-phase motors are used for the drive technology. On request, particularly quiet running, water-cooled motors are used. Likewise, high-torque motors without gears are available as direct drive in various sizes.

High customer value

  • brushless, maintenance-free drive technology
  • High specific output
  • Low energy consumption
  • effective degassing
  • No pre-drying necessary
  • Compact size

Flat Sheet Dies

Created with Sketch.

BREYER flat sheet dies are developed with state-of-the-art software, built in 3D design, and manufactured on CNC machines. They get their high-quality finish through the selection of materials and coating depending on the application, combined with a professional polish. Decades of experience and control of the complete extrusion process enable this perfection.   

 

The program includes single layer and multi-layer dies, with widths of up to 2800 mm. The dies are used for manufacturing flat films (typical thickness range of 0.05 - 1.5 mm) and also for sheet production (thickness of 1 - 25 mm).

All common thermoplastics as well as so-called engineering plastics can be processed. BREYER dies are used in BREYER extrusion lines but also in systems from other manufacturers.

BREYER film and sheet dies are available with the following additional equipment:

  • Rapid lip gap adjustment
  • optimised die shape
  • Restrictor bar
  • Deckling systems
  • Collision protection
  • Thickness measuring systems
  • Control system
  • Die suspension
  • Die carriage


Calenders

A system is only as good as its components.This especially applies to extrusion lines. For this reason, we at BREYER have given special attention to each and every component of the system – especially calender technology. It is decisive for the final quality and performance of a system. Our specialists have come up with innovative solutions for the drive system, which avoids surface distortions or lateral marks.

Maintenance-free servomotors and precision gears provide sustained top-quality results. Thanks to the modular design of the individual system components, the special calender technology made by BREYER is highly flexible and can therefore be practically used for any extrusion or co-extrusion process. 
Whether flat film or clear sheet – with BREYER you're always one step ahead of your competition when it comes to the important production step of «calendering».

The advantages of the BREYER calender technology at a glance:

  • Simple user interface
  • Rapid change of sheet thickness with the servo-hydraulic gap adjustment
  • Smallest thickness tolerances when using BREYER solid calender rolls
  • Flexibility in sheet thickness and cooling process – with the slewing device of the calender
  • High operational reliability by using maintenance free drive technology 
  • Rapid conversion with the roll change system for embossing rolls 
  • Automatic calender roll recognition after roll change 
  • Collision protection system 
  • Digital position display for fast set-up of the calender system

Winders

Sometimes form alone outshines the competition the market. It is therefore not without good reason that superior winding technology represents another major part of our scope of supply.

One such example is the fully automatic winding machine. These machines are always in demand wherever there is a need for precise, straight edge winding, even when the production speeds are high.
This type of machine can also be equipped with a semi-automatic winder spindle or bale handling system.

Or let’s consider the large roll winder with a preceding accumulator, which permits winder diameters of up to 2000 mm. The drives are either electric or hydraulic. On request, they can also be used directly on the secondary processing machine, as a realistic and low-cost alternative to the winding machine. Both winding systems can also be fitted with length and cross cutting equipment. 

Monitoring Systems

The BREYER monitoring system fascinates with its simplicity in operating. The operator is navigated intuitively by the system to the required information and achieves his aim quickly.

The system contains a multitude of features which help the user to 
control and survey the production process and quickly access data. 
For our worldwide clients the system will be delivered in the required 
national language. Via remote access we can keep an eye on your line and are able to assist you, any time and in any case.
