A new and sustainable solution
A balcony slab usually has a thick volume section and a raised edge.
The cut-out (shape) must correspond to an upside down model. The mould then only requires a cover of at least 2-4 cm of the difference in height between the total thickness of the slab on the ground. This is achieved by adding a liquid wax.
The edges of the plate are defined by wax bars and a length that exceeds the length or width of the plate.The lines on which the wax bars are to be placed are projected onto the table by a line laser located on the ceiling.
The wax bars are arranged and fixed at the corners in such a way that the space formed for the plate to be cast is made tight.
The outlines of the plate defined by the wax bars are smaller than the original outlines of the plate. This means that the edges of the mould can also be milled.
Now liquid technical (CNC-machinable) wax with a melting point of approx. 70° is poured into the wax mould, but only in a quantity that corresponds to the height of the raised edges of the balcony.
