Sand casting is a technique in which a negative print is made of all sides of the object. These parts are then removed from the object, the original object is removed, and the loose mold parts are reassembled and secured. This creates a hollow mold. You can then pour liquid metal into this.

Sand casting

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.

Prior to your project, discuss the timeline with one of our advisors.

Time indications

Producing mold, 2 parts (oil-bound casting sand) 3 hours on average
Producing mold, per part (furan sand) 3 hours on average
Casting and cooling 1 day on average (depending on volume)
Post-processing depending on preferences

We would love to meet you, to see what we can do for you and your project. If we can help you, we will discuss your process further. For sand casting, we start from a model that is releasing and made of a non-moisture-containing material (e.g. do not use a model made of wet clay, wax, etc.).
