Mould for casting concrete blocks. the design intent of this mould is to allow for the various components to be laser cut from 5mm steel plate and welded up in the quantity required. So what this further means is that somone in a rural setting but with access to a welder, could order the plate parts from the closest laser cutter and have the parts on hand to make up the moulds as production required and not need any engineering machinery to get the job done.
