Supporting Products for Concrete Pre Cast Application
Semi-dry products are manufactured in a heavy block making machine. The concrete is compacted in a mould due to the pressure of the tamper head and the parallel vibration below the transportation board. These special boards can be made of wood, coated wood, plastics or steel. They are of highest importance for the quality of the semi-dry products: deformation of the board and defects in the surface of wood boards reflect on the bottom side of the precast elements which can lead to claims. But the boards themselves have a value which needs to be maintained.
