Induction Annealing Line

Cooling
The output inductor features a custom manufactured ferrite core with an air gap designed to focus magnetic fields. This means there is no work coil, and therefore nothing to burn out or need replacing. Because there is no work coil, there is also no need for water cooling. The ability of the annealing machine to run for extended time depends partly on the ambient room temperature. A room temperature of 70 degree F/20 degree C is ideal.
Thermal Protection
In common with any induction heater, with extended use, the output inductor will gradually heat up. Multiple fans are installed in the annealing machine to keep the circuitry and inductor cool After 40 to 50 cases have been annealed, the top of the unit behind the pilot will start to feel warm to the touch. This is normal.

In the event that the output inductor should reach 190 degree F/90 degree C (inside the machine), a thermal cutout will activate to protect the unit. If that occurs, leave the induction annealing line turned on so the fans continue cooling. It will automatically reset after 30 minutes, once cooling is complete.

Run Time
The new circuitry means that the annealing machine can be run continuously for a minimum of 200 cases on any program setting without approaching cutout provided that the ambient temperature is around 70 degree F/20 degree C. Many users go well beyond this.

Safety
The induction annealing line features a full-shielded housing. By the very nature of induction, electromagnetic interference is produced when the unit is powered up. If uncontrolled, this can affect other electric devices such as radios. For that reason, federal regulations apply. The shielded housing and electrical filtering effectively blocks and contains all these emissions. This induction annealing line has now passed all international EMC standards. The unit even features internal shielding enclosures to ensure accurate and reliable performance.

Innovations
Uniquely, the induction annealing line has adjustable power and time settings built into the pre established programs. This allows small and very precise increments in annealed neck hardness. When setting the correct program for new brass, we start low and work up until we achieve the target hardness of 105Hv.

Ergonomics
We have not attempted to include an auto-feed function at this stage. The induction annealing line is designed for the user to accurately insert each cartridge manually to exactly the same point in the air gap every time. We have found that a variation of just 2 mm makes a significant difference to the resulting hardness. Once the user is familiar with the use, it can be cycled at around 5 to 6 cases per minute or for comparison purposes, about the same amount of time as case sizing or bullet seating. Auto-feeding may be re-visited at some time in the future.
