Thermo-Line-Bending is the process of using a thin heating element and heat shields that create a thermal aperture that focuses the heat on a defined line along which the part is bent to a specific angle. This allows for very precise bends and angles without distorting the surrounding material. The material texture and even printed graphics can be maintained. A V-notch cut from the inside insures accurate positioning of the bend and makes sharp inside corners possible. This is essential for parts designed to clip onto a mating piece or snap-lock a circuit board in place.
