Overview of Thin Film Silver Plating Technology

Thin film silver plating, as the core process of PET reflective film, involves a series of complex physical or chemical processes to uniformly deposit a very thin layer of silver on the surface of PET substrate. This process not only requires excellent adhesion between the silver layer and the PET substrate, but also ensures a smooth surface, high reflectivity, and uniform consistency of the silver layer. Currently, the mainstreamSilver plating technologyIncluding vacuum evaporation plating, sputtering plating, and ion plating, each method has its unique advantages and application scenarios.

Fine control of production process

The thickness customization of PET silver plated reflective film comes from the fine control of the production process. During the production process, precise control of parameters such as silver plating time, temperature, air pressure, and plating solution concentration can be achieved to precisely control the thickness of the silver layer, covering a range from 4.5 microns to 188 microns. This technological breakthrough not only meets the diverse requirements for reflective film performance in different application scenarios, but also provides the possibility for further optimization of product performance.

1. Vacuum evaporation plating: Using electron beam or resistance heating to evaporate silver material and deposit it on PET substrate in a vacuum state. By adjusting the evaporation rate and time, precise thickness control can be achieved.

2. Sputtering plating: Under high-energy particle bombardment, silver target atoms are sputtered and deposited on PET substrates. By adjusting parameters such as the distance between the target and substrate, sputtering power, etc., customized thickness can be achieved.

3. Ion plating: Combining the principles of vacuum evaporation and sputtering, using ion beam to accelerate the deposition of silver atoms, and supplemented by ion bombardment to enhance the bonding force, to achieve high-quality and high-precision silver plating process.
