R2R Machine Layout
The RT-R2R web aluminum vacuum metallizer features support a range of functionalities that make it the ideal choice for any industrial workshop.
First, it has a high throughput rate which helps to reduce production costs. It also has a heavy deposition layer which is perfect for high barrier applications. Moreover, its process of free-span eliminates the need for a drum line and edge trim. This makes it particularly friendly for low tension substrates like CPP, BOPP and LDPE.
In addition, it has individual wire feeds that make it very user-friendly. Maintenance is also easy. The web handling mechanism with servo motor drives gives precision control at any line speed. Lastly, the compact design occupies minimal floor space for easy installation.

The process of R2R (Roll-to-Roll) web vacuum metallizing involves depositing a thin layer of metal, typically aluminum, onto a flexible substrate in a continuous roll-to-roll manner. Here are the key steps involved in the process:
1. Substrate Unwinding: The process begins with a roll of the flexible substrate material, which is unwound and fed into the metallizing machine.
2. Cleaning and Pre-Treatment: The substrate may pass through a cleaning section to remove any surface contaminants that could affect the adhesion of the metal coating. Following cleaning, the substrate may undergo pre-treatment processes such as corona treatment or primer application to enhance the bonding between the substrate and the metal layer.
3. Metallization Chamber: The heart of the R2R web vacuum metallizing equipment is the metallization chamber. The substrate enters the chamber, which is maintained at a high vacuum. The chamber typically consists of a series of evaporation sources or cathodes, which contain the metal (such as aluminum) to be deposited.
4. Metal Evaporation: The metal within the evaporation sources is heated to its evaporation point. As the metal evaporates, it forms a vapor cloud within the chamber. The vaporized metal atoms travel in straight lines and condense onto the moving substrate, forming a thin, uniform metal layer.
5. Substrate Cooling: After the metallization process, the coated substrate passes through a cooling section, where the metal layer solidifies and stabilizes.
6. Substrate Winding: Finally, the metallized substrate is wound onto a roll, ready for further processing or use in various applications.
It's worth noting that the specific details and parameters of the R2R web vacuum metallizing process can vary depending on factors such as the desired metal coating, substrate material, and intended application. The process can be optimized to control factors like coating thickness, adhesion, and uniformity to meet specific requirements.
R2R web vacuum metallizing offers advantages such as high production speeds, precise control over coating thickness, excellent adhesion, and the ability to process a wide range of flexible substrates, making it a versatile and widely used technique in industries such as packaging, electronics, automotive, and more.
