This is the extension of the 1+1 system. It has all the same advantages, but, thanks to the two additional planes, can double the production capacity. The 2+2 system can be supplied as a ready first system or as an addition to existing 1+1 machines. The two systems share main accessories and can be equipped with further devices for the handling of sheets and panels.
The dimensions of the machines are defined on a case-by-case basis together with the customer according to products and production requirements. With the right accessories, it is possible to produce more than one panel per plane and manage the production of different thicknesses simultaneously.
The system’s modern safety features, compliant with the most recent standards and regulations, allow practical and safe use.
Suitable for those who want to have higher productivity than with a simple multi-compartment press.
No tray required
No roller recirculation
Systems for panel or sheet handling may also be necessary (depending on the size of the product), such as suction cups, handlers or tippers.
The open-mould foaming system is an example of one of the most advanced technologies applied to discontinuous insulating panel production. The casting of the foam into the open cavity allows an ideal density distribution with great advantages for mechanical resistance and insulation capacity.
Since the product is distributed over the entire surface of the panel, the foam only has to expand vertically, providing considerable reductions in extraction times and packing degree, thus allowing a further reduction in raw material consumption. In many cases (e.g. large panels with reduced thicknesses or with complex shapes or internal inserts that may obstruct the injection in a closed mould), the open-mould foaming is the only technology possible for the creation of quality panels.
The most common system configuration is the so-called 2+05, and, in practice, it consists of a trolley press where two trolleys are dedicated to foaming while the third is used for the press loading of the upper panel sheet.
