Abstract
A plurality of individual pre-shaped cores or pins are initially positioned in a prearranged orientation upon an outlet surface of a die body by means of a plate of photosensitive glass or glass-ceramic material which has been etched to form a mask with the desired pattern or arrangement of openings for orienting said cores or pins upon said die surface for subsequent securement thereto such as by welding.
