burnout:
Burnout is the act of removing the wax or other temporary materials from metal castings during the casting process using heat, thus forming a clean mold that the metal can pour into.

Key Features:

  • ​Wax and Other Material Removal: The removal of wax patterns, resins and other temporary materials in the process of building molds.
  • High-temperature Process: Burnout should take place in kilns or furnaces for complete burnout.
  • Accurate Casting: Make sure that the final cast piece captures every fine detail of the mold.


Burnout has great importance in precision casting such as investment casting techniques which are required to make very intricate parts. Examples are in aerospace and automotive applications where burning enable a turbine blade and engine component to be formed according to specifications. Secondly, delicate designs such as those in jewelry or fine metalwork are maintained as all wax patterns are removed, leaving only the final metal shape. New burnout methodologies such as controlled temperature cycles and vacuum-assisted burnout have increased effectiveness and quality in present-day casting practices
