Hot Air Oven

Curing ovens heat materials and cause a chemical reaction that would strengthen them. The temperature in the chamber has to reach a specific level to induce a reaction. 

The materials are loaded in the chamber and exposed to the designated temperature. 

For example, to manufacture brick, you need to cure the dried brick mass at 500° C to make it harder. You’d put the mass in the heated chamber and raise the temperature to complete the curing.
