Sow Mold — Single Chamber Configurations and Model Range

SMI single chamber sow molds are designed for casting aluminium sows from molten metal or recovered aluminium in primary casthouse and secondary remelting operations. Five standard configurations cover a capacity range from 0.077 m³ to 0.37 m³. All models are manufactured from SMI’s proprietary material formulation — optimised for rapid cooling rate and thermal shock resistance, extending service life in high-cycle casthouse environments. Custom dimensions are available to customer drawing or specification.

Standard Model Range — Single Chamber Sow Mold

All dimensions are in millimetres. Weights and capacities are nominal — actual values may vary depending on final design configuration. Custom dimensions available on request.

About Single Chamber Sow Molds

The single chamber sow mold provides a single casting cavity for producing one aluminium sow per pour. The open-top design allows molten aluminium to be poured directly from a ladle or transfer crucible into the mold cavity, where it solidifies into a sow of consistent dimensions suitable for transport, storage and remelting. Wall geometry and base configuration are optimised for consistent solidification, easy sow release and stable stacking after casting.

Material

All SMI single chamber sow molds are manufactured from SMI’s proprietary material formulation — developed over 30 years of continuous supply to aluminium casthouses worldwide. The formulation delivers rapid cooling rate and thermal shock resistance — the two performance requirements that determine service life in high-cycle casthouse environments. Alternative material options are available for specific operating conditions on request.
