Artificial aging is what makes the metals hard. They normally take long periods of time depending on the final temper desired. We age many jobs for a total of 36 hours. This process is continuously monitored by Quality Control. Before the parts go into the ovens, Quality Control verifies that the paperwork is correct and at that time the work is put into the ovens. At a minimum of 1 hour, Quality Control verifies that each and every oven is working properly by checking temperature strip charts, and the multipoint logs.

In addition to the checks performed by Quality Control, all of the ovens are equipped with over-temp controllers. These controllers monitor the temperature for rises in heat. If the oven begins to overheat, the over-temp controller will kick in and turn off the burners. At that time an alarm will sound warning the personnel that something is wrong. The equipment failure is corrected immediately.

When the time is up and the parts are believed to be at the desired temper, they are transferred to the Final Inspection department.
