Abstract

The invention discloses a manufacturing method of a gold and silver double-color pattern crystal standing table. The method comprises the following steps that a chromium copper seed layer is obtained through magnetron sputtering; photoresist spin coating is carried out, selective photoetching is carried out in the middle zone of the standing table, and a first mask pattern is exposed; electrosilvering is carried out on a window of the first mask pattern till the top end of a silver layer exceeds the plane of a photoresist mask, and dull polish treatment is carried out on the top end of the silver layer till the top end of the silver layer is flush with the surface of photoresist; a second mask pattern is used for carrying out selective photoetching in the annular edge area of the standing table, and a second mask pattern is exposed; electrogilding is carried out on a window of the second mask pattern, and an electrogilding layer is obtained; and the standing table is arranged in acetone, glue removing is carried out through ultrasounds, and cleaning and drying are carried out. The crystal standing table obtained through the manufacturing method is rich and diverse in pattern and color. The third dimension of a product is high, the method repeatability is good, and the manufacturing method is suitable for industrial batch production.

Description

technical field [0001] The invention relates to the field of crystal handicrafts, in particular to a method for making a gold and silver double-color pattern crystal table. Background technique [0002] With the improvement of people's consumption ability, more and more crystal handicrafts have entered people's lives. There are many kinds of crystal handicrafts with different shapes. Crystal table is a common one, and the value can be enhanced after the surface of the crystal is plated with gold or silver. Simple gold / silver plating on the crystal surface is too monotonous and has no three-dimensional effect. People hope that the crystal surface can have fine patterns and rich colors. The demand is getting stronger and stronger. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the purpose of the invention is to provide a method for making a gold and silver two-color pattern crystal table. [0004] Techni...
