Wet Casting WF Machine

Wet Casting WF Machine

The new generation of series WF Wet Casting machines represent the state of the art in the production of prestressed concrete products with special attributes such as exposed wire and a corrugated upper surface. 
The NORDIMPIANTI Wet Casting machines offer a cost-effective solution for companies that are looking for a flexible approach to produce hollow core slabs, solid slabs, inverted T-Beams, lintels that require these special attributes. 
The WF Wet Casting machine casts elements in a single phase using the vibration method without the need for formworks. To start production of a different element it is only necessary to change the finishing mould mounted on the machine. This is a quick and straight forward operation. Standard heights range from 60 mm to 300 mm while the width can be up to 1200 mm.


Slipformer Series SF

Slipformer SF Machine

Slipformer SF Machine

NORDIMPIANTI’s sf Slipformer machines have been designed for the production of a wide range of prestressed concrete products both for floors and walls on long production beds.
The machine offers a cost-effective solution for companies that are looking for a flexible approach to produce prestressed elements such as hollow-core slabs, inverted T-beams, vineyard posts, lintels, half slabs, solid slabs, inverted double T beams, grandstand panels and other special shapes. The Slipformer casts elements in a single phase using the vibration method without the need for formworks. 
Concrete is delivered from the main hopper by feeding tables into delivery hoppers mounted on the forming insert. From here the concrete is delivered to the production bed and the voids are formed by a set of forming tubes. Special vibrating groups provide a two stage vibration process ensuring an excellent level of compaction at every point along the element. 
The machine is modular and the power unit together with the hopper can be easily and quickly transferred to another forming insert to produce a different element. Standard heights range from 80mm to 1000 mm while the width can be up to 1200 mm. Different widths are available according to customer requirements.
The heights of the elements, as well as the thickness of the vertical ribs can be varied within certain limits according to the applications and the element specifications required.


EVO2 Extruder

Extrudeuse EVO2

The new generation series of EVO2 extrusion machines represent the state of the art in the production of prestressed hollow core panels.
Available in 5 versions depending on the type of elements to be produced, the NORDIMPIANTI Extruder offers cost-effective solutions for companies who are looking for a flexible approach to produce hollow core slabs in various sizes.

The Extruder casts elements in a single phase using the extrusion method without the need for vibration thus keeping the noise of the machine to a minimum. The machine is modular and the power unit together with the hopper can easily be transferred to another forming insert to enable a slab with a different height to be produced.

Standard heights range from 150 mm to 520 mm while the widths available are 600 mm, 1200 mm, 1250 mm, 1500 mm and 2400 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.
