The invention discloses a
machining technology for a retro silver cup. The
machining technology comprises the following steps of silver
ingot stripping and
slicing, melting, mold reversing,
tempering,plate pressing, discharging, stretching, molding, annealing, pattern pressing, cleaning, retro treating and packaging. According to the
machining technology for the retro silver cup, the machining technology is a novel technology researched and developed on the basis of combination of a traditional technology and a modern technology, and compared with the traditional technology, the aspects suchas patterns, lines and modeling are all greatly improved, the technology is suitable for large-scale production, the machining speed is high, the embossment effect is better highlighted, and the silver cup has the retro color and is fashionable, beautiful and exquisite in
workmanship. Through the pattern pressing process and the retro treating process, the silver cup is more attractive in appearance and pure in color, the fashion sense is increased, and the good collection value is achieved; and the retro silver cup treated through the method is high in
hardness and not prone to being deformed, has no
chemical residue, and accords with the
health maintenance concept of modern people.
