A controller alters a cycle time of a die arrangement, configured to hot stamp metal into components and having an active cooling system, based on an amount of heat transferred from the components to the active cooling system such that a grain structure of the components transitions from an austenitic state to a martensitic state.

The hardness of a rail after the rail having a temperature equal to or higher than an austenite region temperature is forcibly cooled in a cooling facility is predicted. A plurality of sets of data for learning composed of a cooling condition data set and output data of hardness are acquired using a model that performs computing by using a cooling condition data set having at least a surface temperature of the rail before the start of cooling and the operating conditions of the cooling facility as input data and the hardness inside the rail after the forced cooling as output data.

A spring induction heater assembly is shown and described. The device has a quench tank incorporated into the design. A motor and drive mechanism provide rotation of a spring about one axis from a first position used for loading, to a second position for heat treatment with an induction coil and a third position where the spring is released dropped into a quench tank. Another rotational system is operational to rotate the spring on a spindle in the second or horizontal position while the spring is located between at least two legs of an induction coil. The induction coil provides even heating to the spring coils thereby providing desired changes to the material properties. The quench tank can have an automated system to remove the springs from the quench tank.
