GALVANOPLASTIC METHOD FOR MANUFACTURE OF PARTS, MAINLY, MOLDING DIES Russian patent published in 1995 - IPC

FIELD: galvanoplastic manufacture of molding dies. SUBSTANCE: molding die is manufactured by multilayer deposition of photoresist on blank, exposure of relief, development, application of metal layer and removal of photoresist. In this case, die relief is formed in several stages, including above indicated operations, and at each subsequent stage, before application of photoresist, mechanical working is accomplished to level relief flush with photoresist. Method ensures manufacture of dies of any complicated relief of large thickness and excludes presence of falls, burrs and other defects. EFFECT: higher quality and ensured preset height and configuration of relief. 3 dwg
