Answer to Question 1
Specific heat determines the amount of heat necessary to raise the temperature of the material. For an injection mold that is cooled, a high specific heat is desired so that the heat from the part that is being molded will not cause the mold to heat. This will minimize the work of the coolant. In a mold that is heated, such as a thermoset mold, a low specific heat will allow the mold to be heated more easily.
Answer to Question 2
