Problems solved by technology

[0004] Most of the existing induction heating devices are aimed at parts with simple structures and regular shapes, while complex surfaces are composed of surfaces with multiple curvatures, including aspherical surfaces, free-form surfaces, and special-shaped surfaces, etc., with variable curvature and complex structures. Through induction heat treatment on the surface, the surface performance can be enhanced, but there are still problems such as difficult heat treatment, uneven temperature distribution, and low heating accuracy.
