The sand-casting technique is especially suitable for loose, uncomplicated objects. The original object remains intact. The costs for a mold are relatively low. Note that the shape of the object must be releasing (you have to be able to pull it out, without having to break the mold); that is a condition.
We preferably cast with bronze and aluminum. We use 2 types of sand: oil-bound casting sand and furan sand. Oil-bound casting sand gives a very precise impression. The sand is firmly compressed in a casting cabinet and thus retains its shape. This sand is especially suitable for simple, small shapes such as tokens.
Furan sand is a coarser molding sand with furan resin as a binder. No fixed formwork is required, so the size of objects is not limited. A mold can be built up from different parts, making complex shapes possible. This material is also suitable for hollow models.
