Induction heating for defence manufacturing
Shorter delivery times, rising demand and zero tolerance for quality deviations define today’s defence manufacturing. Induction heating delivers the speed and repeatability mission-critical component production requires — heat generated exactly where it’s needed, with no open flame, minimal distortion and fully repeatable results at any scale.
Why induction heating for defence manufacturing
- Fast — a small metal component can reach a uniform surface temperature of 1,000°C in under one second
- Accurate — customised coils deliver the right heat pattern exactly where needed, with minimal energy consumption
- Controllable — transistorised power supplies and process control software give complete control over the heating cycle
- Repeatable — temperature, penetration depth and heat pattern reproduce precisely across large production runs
- Clean, safe and compact — no gas, no open flame, minimal floor space compared with furnace-based alternatives
Armoured vehicles and land systems
- Shrink-fitting of gears, bearings and axles for tracked and wheeled military vehicles
- Pre-heating prior to welding of armour components
- Hardening of drive system parts and track belt links for durability
- Brazing of hydraulic and cooling system components
- Motor and engine components: gears, crankshafts, camshafts, pistons, connecting rods, engine valves
- Transmission and drivetrain: transmission gears, drive shafts, final drives, sprockets, clutch components, bearing elements, track system components
- Rubber-to-metal bonding through vulcanisation, and removal of vulcanised rubber from tank wheels for maintenance and recycling
Naval and military vessels
- Deck and bulkhead straightening using ENRX’s Terac system
- Hardening of propeller shafts and drivetrain components — couplings, gearbox gears and pinions, propeller hub components
- Brazing of piping systems, valves and cooling units
- Engine and motor parts: shrink-fitting of stator housings and rotors, hardening of shafts, short-circuit ring brazing, brazing of conductors, varnish curing, magnet bonding, epoxy curing, connector coating removal, heat treatment of crankshafts, camshafts, engine valves and drive shafts

Ammunition production
- Case hardening of firing pins, mechanisms and tooling
- Pre-heating for forging and forming of steel components
- Annealing of cartridge cases using two purpose-built systems:
- Tip Annealing System — vertical scanning with individual part indexing and a U-shaped coil optimised for case neck and shoulder geometry, for uniform temperature distribution and repeatable results
- Body Annealing System — continuous horizontal scanning with a solenoid coil for full-body coverage, built for high-throughput continuous production
- Both systems support optional integrated cooling for consistent material properties
Customised solutions
For heat treatment of cartridge cases
ENRX Tip Annealing System
The ENRX tip annealing system is designed for precise heat treatment of cartridge case necks and shoulders. A controlled vertical scanning process combined with individual part indexing ensures accurate positioning and stable heating. During the process, part rotation through the induction coil provides uniform temperature distribution and repeatable results. A U-shaped coil optimised for tip geometry enables efficient energy transfer and controlled heating depth. Optional integrated cooling supports consistent material properties.
ENRX Body Annealing system
The ENRX body annealing system is developed for high-throughput heat treatment of cartridge case bodies. A continuous horizontal scanning process ensures efficient part flow and stable positioning throughout the heating cycle. A solenoid coil designed for full-body coverage delivers uniform heat distribution along the case. The system is optimised for process stability and repeatability in continuous production. Optional integrated cooling solutions are available.
