Abstract
A process for producing structural elements, preferably prototypes, in which a “lost” model, i.e., positive model, of the structural element is produced in a first step and the model is subsequently cast with a molding compound to produce a negative mold. The mold is then used for manufacturing the structural element, preferably a prototype, by casting. The model is cast and/or filled with the molding compound in a plurality of successive steps and the position of the model relative to a reference plane is changed in each of the individual steps of casting or filling.
Claims10
A process for producing structural elements, comprising:
- producing a pattern of the structural element, said pattern having cavities;
- feeding said pattern with a molding compound in a plurality of successive feeding steps, said feeding steps comprising:
- (a) changing the orientation of the pattern to a position that is not the original one,
- (b) then pouring the molding compound into a part of the pattern,
- (c) then turning the pattern to another position;
- (d) then pouring the molding compound in again;
- (e) repeating steps c and d until the pattern is entirely filled;
- removing the pattern;
- and
- manufacturing the structural element by casting.
