All creations are available made to measure by "la forge des plaines" and can be quoted.
Wet sand molding is the oldest technique. Foundry sand is composed of a mixture of refractory sand (silica) and a binder (bentonite) which is humidified and mixed in a grinder. This mixture will be used for the design of single-use molds. The part used for reproduction is called the master model. It can be made of wood, resin or metal. The model will be slightly larger than the final part, to account for the shrinkage of the cast metal during cooling.
The model will be placed halfway into a metal frame filled with sand compacted with a rammer. A second frame prepared in the same way will cover the first to conform to the shape of the part. The model will then be removed, and channels will be dug in the sand to feed the model's impression during casting.
Once the mold is made, casting can begin. Molten bronze (1050°) is ladled from the crucible and then poured into the mold. The pouring must be executed at a regular speed adapted to the desired part.
Shakeout consists of demolding the cast part by breaking the sand mold. The latter will be manufactured repeatedly for each new creation.
