The process has three parts. First, the first projection part(8)(9) and the second projection part(12)(13) are molded by plasticity machining, and mainly utilize the long-direction projection part(2) (3). Second, the process forms a blanking of each external part(7) at the plane part (42) of the plane-wire material. Finally, the blank is inscribed with the appropriate element required in the manufacturing of slide fastener coupling elements.
