Co2 Sand Core Making Process For Moulding

Apr 25 2014 The core sits on ‘prints’ at each end of the casting maintaining the gap between the mould and the core for the flow of metal and ensuring the correct metal width is achieved Making the moulds and cores for the Gridiron building at One St Pancras Square exemplifies this entire process.
