Embodiment 1

[0020] After a round crystal table is cleaned, it is processed into a propeller-shaped inner core and an outer ring sleeved outside the inner core; a layer of bright copper is sputtered on the surface of the inner core, and the thickness of the bright copper layer is 50nm , wherein, the side of the inner core is sputtered with a 3 μm silver film and coated with photoresist on the surface, the hanger is placed, the front surface and the rear surface of the inner core are exposed to the electroplating solution for gold plating, and the electrolytic solution for electroplating gold includes sub- Gold sulfate 50g / L, 2-thio-5,5-dimethylhydantoin 120g / L, succinimide 50g / L, potassium citrate 40g / L, citric acid 70g / L, antimony tartrate Potassium 2g / L, polyethylene glycol 1g / L, sodium sulfite 100g / L, isonicotinic acid 6g / L, the pH of the plating solution is 4.1, and the current density is 0.5A / dm 2 , to obtain a 35 μm thick gold-plated film. Then put the gold-plated inner core into th...

Embodiment 2

[0022] After cleaning a square crystal table, it is processed into a propeller-shaped inner core and an outer ring sleeved outside the inner core; a layer of bright copper is sputtered on the surface of the inner core, and the thickness of the bright copper layer is 50nm. Among them, a 2 μm silver film is sputtered on the side of the inner core, and a photoresist is coated on the surface, and a hanger is placed, and the front surface and the rear surface of the inner core are exposed to an electroplating solution for gold plating. The electrolytic solution for electroplating gold includes sub- Gold sulfate 30g / L, 2-thio-5,5-dimethylhydantoin 60g / L, succinimide 30g / L, potassium citrate 20g / L, citric acid 100g / L, antimony tartrate Potassium 3g / L, polyethylene glycol 2g / L, sodium sulfite 150g / L, isonicotinic acid 10g / L, the pH of the plating solution is 5.4, and the current density is 1.0A / dm 2 , to obtain a 50 μm thick gold-plated film. Then put the gold-plated inner core into ...

Embodiment 3

[0024] After cleaning a fan-shaped crystal table, it is processed into a propeller-shaped inner core and an outer ring sleeved outside the inner core; a layer of bright copper is sputtered on the surface of the inner core, and the thickness of the bright copper layer is 50nm. Among them, the side of the inner core is sputtered with a 5 μm silver film and coated with photoresist on the surface, and the hanger is placed on the front and rear surfaces of the inner core to be exposed to the electroplating solution for gold plating. The electrolytic solution for electroplating gold includes sulfurous acid Gold 30g / L, 2-thio-5,5-dimethylhydantoin 10g / L, succinimide 10g / L, potassium citrate 10g / L, citric acid 40g / L, antimony potassium tartrate 1g / L, polyethylene glycol 1g / L, sodium sulfite 20g / L, isonicotinic acid 2g / L, the pH of the plating solution is 4.1, and the current density is 1.0A / dm 2 , to obtain a 20 μm thick gold-plated film. Then put the gold-plated inner core into the ...

Abstract

The invention discloses a manufacturing method of an embedded type gold and silver double-color pattern crystal standing table. The method comprises the following steps that crystals are machined into an inner core and an outer ring arranged outside the inner core in a sleeving manner; a layer of bright copper is sputtered on the surface of the inner core; a silver film is sputtered on the side face of the inner core; the surface of the silver film is coated with photoresist, a hanging tool is arranged, gold plating is carried out on the front surface and the rear surface of the inner core, and gold plating films are obtained; the gold plating inner core is placed in acetone, photoresist is removed in an ultrasound manner, and cleaning and drying are carried out; and finally, the inner core is embedded in the outer ring. According to the manufacturing method, the three-dimensional model of the standing table is improved through the structure that the inner core is embedded in the outer ring , silver plating is carried out on the side face of the inner core in the embedding structure, gold plating is carried out on the front surface and the rear surface, and the color contrast ratio and the three-dimensional ornamental value of the standing table can be increased. The manufacturing method is simple and fast, and repeatability is good.

Description

technical field [0001] The invention relates to the field of crystal handicrafts, in particular to a method for making an inlaid gold and silver two-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 of the prior art, the purpose of the present invention is to provide a method for manufacturing a mosaic gold and silver two-color pattern crys...
