Producing hardened high-strength component used in body making part for motor car, by press curing circuit board, heating board using hot forming tool and simultaneously punching the board, and integrally forming connector with component

摘要

The method comprises: press curing a circuit board at appropriate temperature; heating the circuit board using a hot forming tool and simultaneously punching the board at a designated place; integrally forming a connector with a component (1) by heating a material surrounding a hole in the hot forming tool before the curing process and reducing the thickness such that an embossed area of the material is cut and shaped into a threaded portion in the form of a sheet metal nut (4) or a spring washer. The connector is integrally formed with the component using a laser beam.
