MASTER RX 700F l 700FTD - Extrusion coaters

The production line comprises a machine in tandem configuration to produce complex structures in one pass at high speed. The line is highly customizable and features 2 extrusion or co-extrusion stations.

The coating unit for applying the primer is equipped with the enclosed chamber doctor blade. Very fast replacement of the doctor blade by means of an auxiliary carriage.
The coating unit features an effective technical solution which avoids the formation of foam, especially during operation with a water-based primer.

The impingement dryer is highly efficient and functional, enabling perfect web handling and thorough cleaning of nozzles and rollers. As the efficiency of the drying and ventilation system is crucial and an important source of energy savings and reduction of CO2 emissions, the recirculation group has been sized to optimize power consumption, and the hood is insulated to prevent heat dispersion.

The heart of the machine is the lamination group which is characterized by a three-roll system with indirect pressure. The rolls, due to very precise engineering, ensure a constant temperature across the entire web, thus avoiding any stress to the material being coated - and improving the adhesion properties of the coated material to the substrate. The point of lamination is fixed giving the best web handling.
Component parts of the extrusion coating and laminating group, such as the chill roll and the pressure rolls are easily and quickly replaced and the whole group affords optimum accessibility for cleaning and maintenance.

Manual or automatic die controlled by a thickness measurements system. The movements of the carriage afford a wide range regulation of the position of the die and optimum control of the extrusion parameters.
All the electrical equipment and the thermoregulation cabinet are located on board to reduce floor space requirement and cabling from the machine to the extruders. All the thermoregulation zones are fitted with fully automatic heating/cooling control systems.
The high performance extruders are fitted on the carriage in a sliding layout to compensate for heat expansion. Different layout configuration for extruder size, screen changer and die.

The production line can be equipped with fully automatic shafted or shaftless duplex winders. Both provide for bi-directional automatic splicing at maximum production speed.
The accurate tension control system has been designed for handling the full range of processable materials.
The efficient technical solutions that optimize the recovery of electrical power enable an important reduction in the level of energy consumption.

Different additional equipment can be added to the production line, such as dosing units, suction of resins device, thickness control system, chiller.

Several solutions are available for reel loading and unloading. They range from fully automatic lifting trolleys to hoist systems, depending on specific requirements.
