IHTW (Induction Heated Quenched and Tempering Spring Wire) is a spring wire with outstanding high tensile strength and high fatigue resistance used for suspension spring for automobiles produced by cold forming process.
This is the 21st century product which enables cost reduction through light-weight spring wire, Ride comfort improvement through quality enhancement and design diversity.
This production line is in fact a semiconductor frequency converter device that controls electronic equipment through switching by a rectifier controlled by silicon semiconductors (thyristor).
