The NANO Extruder machine represents the state of the art in the production of hollow core slabs suitable for use as either non-load bearing partition walls or as a thin floor slabs elements.
Depending on the type of elements to be produced, the NANO extruder from Nordimpianti offers cost-effective solutions for companies who are looking for a flexible approach to produce thin hollow core walls and floors in various sizes and applications.
The Extruder machine casts elements in a single phase using the extrusion method.
The machine is modular and a slab-specific product module can easily be changed in order to produce an element with a different height.
Standard heights range from 80 mm to 120 mm in element widths of either 2x600 mm or 1200 mm. The heights of the elements, as well as the thickness of the vertical ribs can be varied within certain limits according to the application and the element specifications required.
The screws then drive the concrete into the compaction chamber (3) where the forming tubes (4) are situated.
The forming tubes and the side formers create the shape and the voids of the element.
Screws, together with the forming tubes, the side formers and the vibrating top plate (5) give excellent concrete compaction at every point along the element ensuring the element’s excellent technical characteristics.
As well as being the main structural component of the machine, the universal casting module also consists of the drive unit for the screws, the wheels, which can be adjusted to change the height of the machine, the support feet for when the machine is parked, the mounts for the sideformers and the vibration assembly.
The universal casting module also contains a slab-specific product module, the type of which is dependent on what product is being produced.
The universal casting module houses the control box fitted with a convenient touch screen operator’s panel. If necessary the machine can be fitted with a cable reel to supply power to the machine depending on the customer’s own installed electrical supply.
The NANO extruder has two hoppers, one above the other. The upper hopper has a capacity of approximately 1 m3. This main hopper allows continuous concrete feeding to the lower hopper by means of a manually operated special double-opening system.
The lower hopper then distributes the concrete within the machine.
Slab-specific product module includes the Archimedean screws and the forming tubes.
Two slab-specific product modules are available.
Changing between the two slab-specific product modules is a simple and straightforward operation and can be done in less than 1 hour.
To adjust the production height between 80, 90 and 100 mm it is only necessary to change the forming tubes and to fit the correct spacer under the lower hopper and vibration group.
The NANO Extruder from Nordimpianti does not require the use of special production beds, it can be used on the same production beds that produce the standard prestressed hollow core slabs on or a simple concrete bed.
On this same production bed the NANO Extruder can cast 2 x 600mm elements simultaneously.
