Real world examples demonstrate the power of precision heat.
Induction heating is an efficient way to quickly heat electrically conductive metals with pinpoint accuracy. The process is used in manufacturing plants in the aerospace, automotive, construction, power generation and medical device industrial sectors among others. How can induction change your manufacturing process? Seeing a process in action is the best way to understand how induction heating works. With that in mind, eldec created a series of real-world examples to help illustrate how the process can make a production line more efficient and improve the quality of parts. Each case study includes video demos of the process and details about how other manufacturers were able to solve production problems. Examples include:
Induction brazing
Induction brazing can be used in a wide variety of applications, ranging from strand brazing flat copper wires for large motor and transformer manufacturing and repair to brazing squirrel cage rotors for electric motors. The process can also be used in steel tube assembly, carbide blade manufacturing and return bend brazing for copper tubing used in refrigeration equipment production.
Shrink fitting
Shrink fitting using induction heat simplifies assembling and disassembling metal parts. The process is quick, and the joints are neat and precise. Gentle, non-contact heat expands the outer mating part evenly without negatively affecting the microstructure, while the inner part is inserted at ambient temperature. As the outer component cools it creates a firm bond. A similar process can be used to remove a mated component for repair or replacement.
Induction annealing, tempering and de-coating
Unlike conventional methods, induction annealing generates heat directly in the workpiece by using an alternating electromagnetic field. The entire heating process is carried out without contact and in a very short time. Often, the cooling process for the part creates less distortion as well because the temperature of the workpiece can be reduced slowly without coolant rather than quickly through abrupt immersion in water or coolants.
Wire stripping
Multi-strand CTC (Continuously Transposed Cable), an insulation-coated, copper wire used primarily in the production of large transformers, can be quickly stripped using induction technology. At a temperature of 1,112° F (600° C), the coating evaporates within seconds, making the process ideal.
