Benefits of the dispenser: The quality of the polyurethane foam for sandwich panels produced continuously is strongly dependent on the control of the wave. If the speed of the line is not well controlled and if the contact point of the wave with the top of the facing is not well positioned the mechanical properties of the produced panel decrease considerably. The spreading system mostly used mostly used at present is the “Poker”, a rake which oscillates in different speeds from left to right and from right to left of the panel. We settle generally a covering around 60 % on the return to the rake. This system contains numerous inconveniences: the distribution is very difficult to make homogeneous, make it cover the foam tends to crush cells in formation of the first passage and the wave is not uniform, thus difficult to adjust. The novelty is the fix foam dispenser, it allows of landing all these problems. The foam is put down on the lower facing in a uniform way and allows of...

Fixed Foam Dispenser For Flexface Continuous Lines Designed with the latest software for flow calculation, our fixed foam dispenser is certainly the best low cost system to improve your production line. Most of actual production lines for flexface panels have a deposit system with 2 outputs per mixing head. The impact velocity on the inner facing is high and the flow output is quite turbulent, a part of the blowing agent immediately turn in gas and lose their effect for the foam expansion. This speed also create bubbles at the deposit. With the new POFI patent, we reduce this effect and increase the foam quality with a non turbulent deposit. The impact velocity is lower and the given angle to the distribution system allows for reduced bubble formation. The uniform arrangement of dispensing dots enables an optimal orientation of cells and thereby to obtain better mechanical characteristics of the panel. Each mixing head output is divided in 4 streams to ensure a better...
