CORE ASSEMBLY
In previous blogs we have explained making sand moulds using wooden patterns. Core Assembly is a different way of making sand moulds for iron casting. Simply put a mould made in this way is like a 3D jigsaw puzzle in negative - the technique requires great skill and takes years to master.
