Morphology

sand + cast

The meaning is directly derivable from combining 'sand' (the material used for the mold) with 'cast' (to form by pouring into a mold); a learner who knows both words can infer it means casting using a sand mold. This fits a common English pattern where a noun specifies the method or material of the verb and is cross-linguistically transparent, so it should be comprehensible to a B1 learner.

Etymology

Sand cast comes from a simple workshop image: makers pack wet sand around a pattern and then pour hot metal to cast a copy. The hot, melted metal fills the sand mold and becomes the object, so Sand cast means 'to form an object by pouring molten metal into a mold made of sand'.
