Chill (Iron chill)

Metallic permanent mold for the repeated production of molded products, in a broader sense also graphitic or metallic permanent mold for the production of centrifugal casting and continuous casting. Centrifugal molds may, if necessary, be coated with refractory materials.

Even in sand molds built chilling plates are referred from the foundry technical view as chills.

In addition, a distinction is made between the full chill, in which all casting outer surfaces are formed by the permanent mold, and the half or mixed mold, in which outer cores made of sand moldings are used.
