Title
(EN) METHOD OF CASTING
(FR) PROCÉDÉ DE COULÉE
Abstract
(EN)
A bed of recyclable moulding casting medium is first laid down and then cut away to produce a mould for a concrete component or an element of other castable material. Once the mould has been used it is recycled for making further moulds. Various cutting devices such as milling bits, lasers and water jets allow the easy production of complex moulds previously not economically feasible for pre-cast concrete components. A large casting bed can be used to make multiple panels in a batch.
(FR)
Selon l'invention, un lit de milieu de coulée pour un moulage recyclable est tout d'abord déposé puis découpé pour produire un moule pour une pièce en béton ou un élément en un autre matériau coulable. Une fois que le moule a été utilisé, il est recyclé pour fabriquer d'autres moules. Divers dispositifs de coupe, tels que des outils de fraisage, des lasers et des jets d'eau permettent la production aisée de moules complexes qui n'étaient auparavant pas économiquement faisables pour des pièces précoulées en béton. Un grand lit de coulée peut être utilisé pour fabriquer de multiples panneaux dans un lot.
