Elmag manufactures a range of lines suitable to cure varnishes and photosensitive inks on any kind of material (paper, plastic and metal), considering printers’ different needs.
The “STREAMCURE” systems are fit to be placed in line, connected either to offset-printing machines or to roller coaters.
Thanks to a long time experience in polymerisation, Elmag has developed a compact and modular system to meet requirements of all users, regardless of the size of their plants.
The LABES reflectors, the state of the art concerning the UV radiation technology, are contained in all aluminium hoods.
Each UV unit is independently cooled. The cooling system has an inverter equipped with automatic adjustment, which allows keeping the light bulb at a correct working temperature for all required levels of power.
Complete ozone extraction is assured by a custom tailored exhaust system.
Each UV unit is equipped with a swivelling device to prevent overheating and conveyor belts wear in case of line stop or emergency.
Optionally it is possible to install on the conveyor UV-Plus units, which allow working either directly towards the substrate or indirectly – Coldcure – in case of thermo-sensitive substrates.
The lamps that Elmag uses in its units are the result of a severe research and a 20 years long selection. These lamps can operate from 60 to 160 W/cm and, if required, have a 3-steps or stepless adjustment from 60 W/cm to max. power.
Conveyor belts are equipped with an adjustable vacuum system. Each belt is driven and has a spring tightener to compensate possible lengthening.
Distance between belts is about 20 mm in order to prevent overlapping.
The adjustable conveyor speed system is equipped with speed digital display, emergency push buttons, 3-colors light showing the machine state, control device and conveyor movement signal.
In the case of 4000 mm long conveyors, the UV unit can be pneumatically lifted for emergencies and maintenance.
For lengths of 8500 mm, the support and UV unit can be moved lengthwise. This allows to change the time of coat application and ensures a good conveyor maintenance.
Stacking is performed by a solid and efficient stacker, consisting of a steel structure, platform with max. capacity of 1200 kg, pneumatic joggers controlled by a photocell, sheet size adjustment, up and down movement of the platform controlled by a capacitive sensor and driven by A.C. gear motor, feed board, sheet-slow up system, sheet-counter with zero setting.
An operation and control panel is placed directly on the line. The electrical equipment is installed inside a control cabinet built according to I.E.C. standards. It has a fan ventilation system and a PLC.
The lamps’ power supply units are easily reachable and follow existing standards.
Optionally it is possible to install an inline display equipped with troubleshooting system. It can perform standard and special control operations:
- separated visual indication of failures
- machine production per hour
- daily production
- advancement of production order
- conveyor speed
- electrical control of each lamp
