Resin Sand Castings:
In resin sand casting the mould differs from the one employed in green sand casting for the different components used and because these are mixed not long before molding.

In resin sand casting phenolic or ureic-furan resins are employed. These are mixed with the sand and then activated by a chemical catalyst that causes an exothermic reaction of variable duration, according to the quantities used, this makes the sand harden, maintaining the shape left by the pattern.

This operation is carried employing a resin-sand preparation plant; the resin-sand is poured into the flask containing the pattern by means of a mixer arm.

The same operation is carried out for obtaining the other half of the mould, which is then mated to the first one. Once the reaction is completed the pattern is removed and the cope and drag, the two flasks that form the resin sand casting mould, are mated. The complete mould is then transferred for casting by means of a bridge crane or a fork lift truck, considering that the resin sand molding technique is ideal for casting very large pieces or for manufacturing thermoforming moulds.
