For fast and accurate maintain engineering
In the aerospace industry, engine components are expensive, so repairing them rather than replacing them has become much more economical.
Batch-type vacuum furnace brazing has traditionally been used to apply heat in this repair, but induction heating can be used in a variety of situations.
Advantages of IH
Utilizing IH power supplies (invertor) with advanced solid-state technology, IH system offers many advantages for heating in a controlled atmosphere.
Compared to batch-type vacuum furnaces, they provide precise, contactless heating in a compact, cost-effective package. This provides fast, accurate, and consistent manufacturing and repair processes.
IH applications in the aerospace industry
In many heat-using processes such as brazing, soldering, and preheating, IH offers high quality heat treatment with no variation in reliability and reproducibility.
Rapid and energy-efficient IH is very effective in repair work that requires quick response.
