Wire heat treatment

The unrivalled accuracy, control and efficiency of induction heating makes it ideal for many key tasks in the manufacture and processing of wire and cable products.

EFD Induction offers solutions for many applications, from structural ferrous and non-ferrous wires, copper and aluminium cable and conductors to fibre optic production. The applications are very wide ranging and include forming, forging, heat treatment, galvanizing, coating, drawing etc., at temperatures from 10’s of degrees to in excess of 1,500 degrees Celcius.

Typical applications include:
  • Drying post cleaning or removing water or solvent from coatings
  • Curing of liquid or powder based coatings. Providing a superior bond strength and surface finish
  • Diffusion of metallic coating
  • Pre heating for extrusion of polymer and metallic coatings
  • Heat treatment including: stress relieving, tempering, annealing, bright annealing, hardening, patenting etc.
  • Pre-heating for hot-forming or forging, especially important for specification alloys

New Generation Minac

EFD Induction has always been at the forefront of technological development and with the new fully digital control system, we set you up for the future.

DIGITAL TO THE CORE
Future-proof: The fully digital control system provides a solid foundation to build on. Easy-to-install software upgrades ensure that your induction ­equipment will always have the latest state-of-the-art ­technology.
Enhanced reliability: Your induction equipment will have ­extended life through our unique, advanced machine audits and trouble-shooting. Enhanced diagnostics will protect you against unexpected costs.
Increased productivity: Better use of your machine data will increase your productivity. You will have unmatched control and efficiency, ­reduced maintenance requirements and shorter service response time.
PREPARED FOR INDUSTRY 4.0 THE INDUSTRIAL INTERNET OF THINGS

With easy updates to new features, your equipment is prepared for developments within:
  • Advanced analytics and predictive maintenance
  • Interconnectivity
  • Condition monitoring and alarming
  • Automation and real-time data
  • Machine learning
  • Remote service and augmented reality
  • Mobile, flexible and easy to use
Mobile: You can move your Minac around a workshop or factory floor. It can easily be loaded into a car and transported to work sites.
Flexible:  It can be fitted with a practically limitless range of coil designs and coil fixtures, flexible cables, closed or separate cooling systems, specially designed heating cables, etc.
Simple to operate:  Handheld transformers (HHT) feature on/off and precise power controls. In fact, the HHT is as easy to operate as a regular electric drill. Flexible, water-cooled cables connecting the HHT to the converter allow easy access to workpieces.
Twin power outputs: Many models come in a Twin version, featuring two independent power outputs that can operate simultaneously.
Complete range: Minacs are available with maximum intermittent output power of 10-220 kW (6-140 kW continuous) and a frequency range of 10-280 kHz. Higher-frequency Minacs—which combine high frequencies with small coils—are ideal for heating small, delicate and complex workpieces.
Robot compatible: Minac can be adapted to any robot, allowing quick, no-fuss integration into automated production lines. The HHT can easily be mounted on a robot arm.
Maximum output power: With Minac’s maximum power feature you can, for limited periods of time, operate with an output power far in excess of the continuous output power.
 
Minac is an all-in-one-solution, ideal for jobs as diverse as brazing, shrink fitting, hardening, curing, straightening, etc.

Seam annealing systems

Induction annealing and normalizing is widely used in the tube and pipe industry. However, induction is ideal for virtually any annealing task.

What is induction annealing?
This process heats metals that have already undergone significant processing. Induction annealing reduces hardness, improves ductility and relieves internal stresses. Full-body annealing is a process where the complete workpiece is annealed. With seam annealing (more accurately known as seam normalizing), only the heat-affected zone produced by the welding process is treated.

What are the benefits?
Induction annealing and normalizing delivers fast, reliable and localized heat, precise temperature control, and easy in-line integration. Induction treats individual workpieces to exact specifications, with control systems continuously monitoring and recording the entire process.

Where is it used?
Induction annealing and normalizing is widely used in the tube and pipe industry. It also anneals wire, steel strips, knife blades and copper tubing. In fact, induction is ideal for virtually any annealing task.
