Casemaker Pro + pressing module 4 sides Grafcut GC-480 Pro 4
GC-480 PRO 4 is a casemaker dedicated to produce hard cover cases. The machine closes all 4 case sides and corners in one pass thanks to two turning in modules. The air is all pressed out during the process.
The glue application unit is used to cover flat surfaces such as paper, leather, PVC with a thin layer of glue. The machine is able to use hot glues, which allows the use of organic adhesives of animal origin, eliminating the risk of cover waving due to the large amount of water in the glue – not requiring a long pressing time of the finished cover, reducing the time needed to clean the machine to an absolute minimum. The offered machine is a simple control, large and durable rollers made of stainless steel, standard equipped with preheating to prevent water condensation on the sheet and water supply from the tank activated by pressing a button. All this makes the work as easy as possible and eliminates many potential problems occurring when operating similar devices.
Casemaking table allows you to work on a variety of materials with different properties. It has centre LED backlight for positioning and motorized conveyor belt with suction that moves in and out the case. The turning in module does not require an air supply and works mechanically, very quietly in comparison to other devices on the market.
Gluing unit features:
can be used with cold glue or hot glue (recommended extra glue tank if using both, machines comes with one tank)
2 stainless steel, big diameters rollers (acid resistant) for better glue application
Electric heater, metal tray with glue disposed into water tank heated by the heater.
Rollers speed fluent adjustment from panel
Preheating bar before metal rollers (prevents water collection on table) in standard
Water tank with pump for adding water to glue tank by pressing button on panel
In standard version made for application of glue for material from 80 gsm to 250 gsm (with optional rigid board module up to 5mm material thickness)
Cleaning time after job about 5 minutes
Casemaker features:
Colour touch screen for settings and diagnostics
Motorized rollers for edge turning in and pressing the case, does not require any compressor. Silent operation.
Motorized, vacuum table (pump included) for moving the case in and out
Possibility to do pressing only or turning in and pressing.
LED cover central backlight from bottom
Board positioner operated by hand
Foot pedal for board stoppers
Top shelf for boards and covers
OPERATION:
The operator manually feeds the cover to the gluing machine where the glue is automatically applied
The cover sheet smeared with glue is placed by operator it on the table, then manually adds grey boards and a spine board.
The operator presses the pedal and case is moved into turning in module. First section closes 2 edges, next corners are closed. Case drops into motorized conveyor belt that pushes it into second turning in section closing next 2 edges. Covers that leave the machine are immediately usable. During the turning in operation, the cover is pressed through a system of guide rollers removing the air.
