Most of our electrotechnical brazing solutions are used for:
EFD Induction offers induction equipment, which performs a variety of preheating tasks within the electrotechnical industry. Some examples are induction preheating of axles and frames before welding, and heat softening of bars before bending.
The purpose of preheating is to reduce the risk of cracking and hardening structures. Induction allows accurate heat control—time and time again. You get exactly the result you require. What’s more, the heat is generated directly in the material, which allows you to speed up the preheating process.
Our compact and mobile induction equipment performs a variety of induction postheating tasks within the electrotechnical industry:
Mobile heat generators
The Minac range of complete mobile induction systems is even easier to use than its acclaimed predecessor.
A ready-to-use system, all that has to be done upon delivery is: 1) attach a coil, 2) connect supply voltage, 3) connect cooling water. In models with closed cooling systems, only the supply voltage needs connecting.
Once installed, the Minac's clear, menu-based and multi-language control panel ensures maximum ease-of-use. Moreover, this simplified control/user interface is common to all Minac equipment.
Many Minac models come in "Twin" versions offering two independent power outputs. The Twin versions feature split control panel displays—one for each power output.
The Minac is 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.
Universal heat generators
Choosing Sinac gives you more than the market's most advanced, most reliable induction heating systems. You also get easy access to EFD Induction’s global service, training and spare parts network. This network—which is made up of manufacturing plants, service centers and local representatives—means you are never far from qualified help and support.
Opting for Sinac also ensures you get the best possible solution tailored to your specific needs and conditions. Prior to designing your system, our engineers, metallurgists and material experts assess your requirements. Testing and computer simulation at our labs guarantee you receive equipment which is optimized to your applications and which can be painlessly integrated into existing production lines and processes.
The use of induction heating for bolt expansion in high-pressure turbines is a powerful business tool.
This case story from Italy illustrates the benefits—speed, reliability, safety—that make Minac induction heaters ideal for heating large bolts.
Induction heating is rightly prized for its versatility. But bolt heating? Is induction really an effective alternativeto traditional gas and resistance heating methods? Here we report on how two customers fared when they turned to EFD Induction to solve their bolt heating challenges.
Power generation and distribution giant ABB recently installed the largest single-shot short-circuit ring brazing system yet developed by EFD Induction.
EFD Induction will be demonstrating a mobile Minac Twin induction heating system at the International Air-conditioning, Heating and Refrigerating Exposition (AHR), to be held January 28-30 in Dallas, Texas.
