Core sand is a mixture of sand grains and organic binders which evolves at a greater strength after baking it at 250 – 600 F. It is possible to create intricate design casting by some casting metal to leave an impression around thin sand projections without breaking them. 

Core making is a process of making the interior part of the casting; here mold provides the space for the molten metal to settle, while the core keeps the metal from filling the entire space left. 

A core is sand or metal insert which is used to put the shape in any part of a casting that cannot be shaped by the removable pattern. When some pattern is pressed in the sand and after that extracted to leave an impression.

  1. Core blowers force the sand in the core box by compressed air and can be used for making all types of small and medium-sized cores. 
  2. Crew feed machines are used to express plain cores, commonly cylindrical. 
  3. Core driers support the shape of a core while it is inside the oven for baking.
