Our casting techniques

Cost-effective casting technology: sand casting

Sand casting is one of the casting processes using so-called "lost molds". The mold is destroyed upon removal of the finished workpiece and can therefore only be used for a single casting. The alloy is cast in hand- or machine-made molds made of quartz sand - hence the name "sand casting". This casting technique allows high-quality and detailed castings to be created without the use of more costly metal molds. In addition, sand casting facilitates a rapid response to modifications in the mold.

Sand casting with attention to detail

Sand casting is particularly suitable for small to medium series, prototype development and the production of components with complex geometries. To create the mold, productspecific models are first fabricated from either metal or wood. Based on digital 3D designs or 2D sketches, the models are then reproduced to scale. The completed model is then pressed in sand as the molding material. Due to its particular composition, the sand retains its shape even after the model has been removed and can now be used as a casting mold. Cavities and challenging geometries are recessed during casting with the aid of so-called cores, which are placed in the molds before casting begins. The alloy matched to the product to be cast is then added to the mold.

OOnce the metal has cooled, the cast component is removed and in the process, the sand mold is destroyed. Subsequently, finishing operations such as deburring the surface or removing sprue pieces are carried out - an individual finish is also possible. Compared with permanent mold casting, castings made by sand casting have a rougher surface. However, geometries are reproduced in precise detail.

Advantages of the sand casting process

✔ Hardly any geometry restrictions

✔ No restriction in terms of the weight of the casting

✔ Great freedom to influence feeding and controlled solidification

✔ Cost-efficient casting technique

✔ Fast reaction to changes in the mold possible
