Abstract
A method of manufacturing plates assembleable in a stack to provide a mold to form fastener elements includes applying a photoresist material to at least one side of the plate. The photoresist material is exposed to light. Portions of the photoresist material are removed based on the light exposure. Acid is applied to the plate, dissolving portions of the plate exposed to the acid and creating cavities.
