resin coated sand preparation and casting production system
Sand Casting
6.4.3 Sand casting. Sand casting involves the pouring of molten metal into a cavity-shaped sand mould where it solidifies (Fig. 6.8 ). The mould is made of sand particles held together with an inorganic binding agent. After the metal has cooled to room temperature, the sand mould is broken open to remove the casting.

Sand Casting Binder
A Phenolic-urethane no-bake resin sand binder system uses a liquid catalyst as the curing component. The products are formulated to deliver optimal core/mold properties and economical benefits by allowing the operator to use a minimal amount of catalyst for complete core/mold cure. Key Benefits: Less Resin Usage per Core/Mold

Resin
In this process, quartz sand is heated in a special heating apparatus to temperatures of 120 to 150 C. Hot sand is mixed up in a core sand mixer together with solid flake-shaped phenolic resin; the resin melts and covers the quartz grains. This process step is referred to as premixing (premixing time is between 40 and 60 seconds).
