General industry
ENRX builds induction machines for railway, wire and cable and infrastructure: shrink-fitting, hardening, coating curing, annealing and coating removal.
Introduction
Beyond the main industries ENRX serves, induction heating is used wherever metal needs to be heated accurately, quickly and repeatably, from rolling stock and rails to wire and cable lines and infrastructure maintenance. Unplanned downtime or unexpected quality defects can quickly turn expected gains into major losses. Induction is accurate, controllable, fast and repeatable, which is why more industries choose it over alternatives such as gas. It also produces no direct emissions and eliminates naked flames.
ENRX builds machines for both kinds of job:
- Mobile induction heating for general tasks
- Stationary induction heating for specific tasks

ENRX has dedicated pages for these industries:
Railway
The accuracy, control and efficiency of induction heating make it ideal for key tasks in the manufacture and maintenance of rolling stock and rails.
- Shrink-fitting of lock rings, ball bearings, brake pad centre hubs, steel tyres on rims and wheels on shafts, including Loctite connections
- Disassembly and assembly of bearing and lock rings in railway repair shops
- Pre-heating of rails
- Hardening of rails and hubs
- Welding of rails in the field
Wire and cable
The accuracy, control and efficiency of induction heating make it ideal for many key tasks in the manufacture and processing of wire and cable products. ENRX designs and builds specialised systems for steel strip and wire and cable pre-heating.
- Drying after cleaning, and removal of water or solvent from coatings
- Curing of liquid or powder-based coatings, giving a superior bond strength and surface finish
- Diffusion of metallic coatings
- Pre-heating for extrusion of polymer and metallic coatings
- Heat treatment, including stress relieving, tempering, annealing, bright annealing, hardening and patenting
- Pre-heating for hot-forming or forging, especially important for specification alloys
Infrastructure and maintenance
Induction heating is used in the maintenance and repair of steel structures such as bridges, where mobile systems can be brought to the work.
- Shrink-fitting and replacement of shafts on bridge structures
- Removal of paint and coatings from carbon steel, structural steel and other metal substrates, with no blast media and up to 90% time saving compared with traditional methods
- Straightening of steel structures during repair
Glass and fibre
Induction heating is a proven way of melting glass as well as metal.
- Induction heating of cold crucibles for glass melting
- Heating of molten glass
- Pre-heating for optical fibre drawing
- Pre-heating of glass wool spinners
Induction brazing joins the metal parts of everyday products.
- Brazing of steel support bars for sofas
- Brazing of microphone mesh and housings
- Brazing of bicycle frames
Process industry
- Pre-heating of steel vessels for chemical and food processing
Silicon and advanced materials
- Melting, crystal growing, crystallisation and purification of silicon, by plasma or segregation
- Plasma heating of titanium and silicon
