The Advantages and Disadvantages of Green Sand

2020-12-31  Resin-bonded silica sand is placed onto a heated pattern, forming shell-like mold halves. Pattern halves are bonded together with or without cores. Probably the earliest, most automated and most rapid of mold (and core making) processes was the heat-curing technique known as the shell process.
