Heat Treating department is what makes this company. When the Heat
Treat department receives parts from Receiving Inspection, they gather
all material necessary to rack a basket. Parts are racked on the
baskets evenly spaced so that the air flow in the furnaces is not
compromised. After all of the parts are racked, a digital photograph is
taken of each individual part number for racking verification. The next
step is to insert the racked baskets into the furnaces.
Quality Control continuously monitors all jobs in process by checking the temperature strip charts every hour. In addition, a multipoint data-logger prints the furnaces temperature every 5 minutes, and saves the data to a disk every 5 minutes as well. If something were to go wrong (such as a burner going out), our Quality Control department would catch the error in a short period of time. In addition, our furnaces are equipped with alarms. When temperatures drop below acceptable range, the alarm will sound.
After the necessary soak time has been accomplished, the parts are quenched. We have 4 primary methods of quenching from air furnaces. They are: Glycol, Cold Water, Hot Water, and Spray. Our Salt bath has 3 primary ways of quenching, which are: Cold Water, Hot Water, and Boiling Water. The parts stay sitting in the quenchant until all necessary heat is extracted from the parts. At that point the parts are rinsed, dried, and transferred to the next stage of processing.
