Embodiment Construction

[0016] Embodiments of the present invention provide a processing technology for imitating metal sheet gold plating, and the whole processing process includes the following steps:

[0017] S1, using sealed heating equipment to melt the alloy into thin metal sheets;

[0018] S2, folding the PET dyed composite film in half, placing the thin metal sheet in the folded composite film, and adding adhesive backing;

[0019] S3, using lamination equipment to heat and press the composite film, so that the upper and lower PET dyed composite films are seamlessly bonded and fixed on the thin metal sheet.

[0020] Wherein, in the above step S2, the PET dyed composite film exceeds the surrounding length of the thin metal sheet and completely covers the thin metal sheet, so as to better realize the seamless bonding and fixing of the upper and lower PET dyed composite films on the thin metal sheet.

[0021] Specifically, the metal thin sheet mentioned above is platinum foil, silver foil, plat...

Abstract

The invention discloses a processing technology of gold plating for imitation metal sheet, which comprises the following steps: using seal heating equipment for fusing an alloy to the metal sheet; folding PET dyeing composite membranes, placing the metal sheet in the folded composite membranes, adding a bonding back glue; using the composite equipment for heating and pressurizing the composite membranes, and bonding the upper PET dyeing composite membrane and the lower PET dyeing composite membrane without slits and then fixing on the metal sheet. According to any white metal sheet after being pressed and sealed through the PET dyeing composite membrane, the finished product can completely reach the verisimilar color effect as gold plating, cost can be greatly saved, and whole processing technology has the advantages of safety, environmental protection and no pollution.

Description

technical field [0001] The invention relates to a gold-plating process, in particular to a gold-plating process for imitating metal flakes. Background technique [0002] Gold plating refers to the use of electrolysis or other chemical methods to attach gold to the surface of metal or other objects to form a thin layer of gold. [0003] The entire gold plating process must be very rigorous, especially for silver gold plating, copper gold plating, and alloy gold plating. If the potion of the nickel tank is not well maintained for a long time, and the carbon treatment is not carried out in time, the electroplated nickel layer will easily produce flakes. Crystallization increases the hardness and brittleness of the coating. , Seriously even lead to the problem of blackening of the electroplated gold layer. [0004] In addition, the electroplating gold layer of PCB is generally very thin, and many problems reflected in the surface of electroplating gold are caused by the poor p...
