Sow Mold — Multiple Chamber Configurations and Model Range

SMI multiple chamber sow molds allow multiple sows to be cast per pour — increasing throughput and reducing cycle time in high-volume primary casthouse and secondary remelting operations. Five standard configurations cover a capacity range from 0.11 m³ to 0.48 m³. All models are manufactured from SMI’s proprietary material formulation — optimised for rapid cooling and thermal shock resistance in continuous casthouse service. Custom chamber layouts and dimensions are available to customer specification.

About Multiple Chamber Sow Molds

Multiple chamber sow molds divide the casting volume into two or more separate chambers within a single mold body. Each chamber receives a separate pour of molten aluminium and produces an individual sow upon solidification — increasing the number of sows produced per handling cycle, reducing crane movements and improving casthouse floor utilisation. The chamber divider geometry and wall thickness are engineered to ensure consistent solidification across all chambers simultaneously, preventing differential shrinkage and maintaining consistent sow dimensions across the full production run.

Material

All SMI multiple 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.
