R2R web aluminum vacuum metallizers offer numerous advantages, including high production speeds, excellent control over the thickness and uniformity of the metal layer, and the ability to process a wide range of flexible substrates.
We provides turnkey coating solutions for ZnS web roll to roll vacuum metallizer, we know how to transfer the technology. The R2R web vacuum metallizer typically consists of the following components:
1. Unwinder: The process begins with a roll of the substrate material, which is unwound and fed into the machine.
Cleaning Section: The substrate passes through a cleaning section to remove any contaminants or particles that may affect the quality of the metallized coating.
2. Pre-Treatment : In this stage, the substrate may undergo pre-treatment processes such as corona treatment, flame treatment, or primer application. These treatments enhance the adhesion of the aluminum layer to the substrate.
3. Metallization Chamber: The heart of the R2R web aluminum vacuum metallizer is the metallization chamber. The chamber is typically a vacuum environment where the aluminum deposition takes place. The chamber contains a series of evaporation sources or cathodes, which heat the evaporation materials to theirs evaporation point. The evaporated aluminum condenses on the substrate, forming a thin, uniform layer.
4. Cooling : After the metallization process, the coated substrate passes through a cooling section to solidify and stabilize the deposited metal layer.
5. Rewinder: Finally, the metallized substrate is wound onto a roll, ready for further processing or use in various applications.
