Sand casting

Sand casting is a very old process, which we have combined with new technologies, enabling us to produce high-quality castings in a short time. Whether you need single pieces or small series, we specialise in casting both non-ferrous and stainless steel alloys. If required, castings can be delivered fully processed.

Fenix uses not only wooden models but also EPS models and 3D printed sand moulds, allowing us to deliver complex castings in a short time.

Fenix specialises in casting single pieces or small series in both non-ferrous and stainless steel alloys.

If desired, the castings can be supplied fully finished.

Innovative approach to sand casting

At Fenix, we pride ourselves on our innovative approach to sand casting. Instead of relying solely on wooden models, we use advanced technologies such as EPS models and 3D-printed sand moulds. This allows us to deliver complex castings both quickly and accurately. Our team of specialists ensures that your castings meet the highest quality standards.

Sand casting process in stages

Sand casting is a casting process in which the mould is made of special sand. The product is poured into the sand mould to create complex castings. For single pieces and small series, sand casting is cheaper than gravity die casting. The stages of our process include:

Stage 1
Assessing the supplied model. If necessary, we will create a new model in wood, plastic, EPS or by means of 3D printing.

Stage 2a
Shaping the model in the sand and applying the feeding and casting system.

Stage 2b
Creating (a) core(s) in castings where cavities or internal structures are required.

Stage 3
The sand mould is hardened.

Stage 4
Removing the model from the hardened sand mould.

Stage 5
Coating the sand mould and cores to improve heat resistance and surface quality.

Stage 6
Assembling the sand mould with the cores and preparing it for pouring.

Stage 7
Melting the right alloy and checking the chemical composition.

Stage 8
Pouring the casting.

Stage 9
Cooling down the casting

Stage 10
Removing the casting from the sand mould.

Stage 11
Removing the casting system and blasting the casting.

Stage 12
Heat treating the casting if required.

Stage 13
If required, we offer several processing and quality control services, including mechanical processing, pickling, glass bead blasting, coating, extrusion, impregnation, LPE, X-ray, wall thickness measurement, ultrasonic testing, PMI test, 3.1 certificate and 3.2 sampling.

Stage 14
Final inspection and preparation for shipment.
