Royal Technology provides a complete line of vacuum deposition systems optimized for depositing thin film materials on complex three-dimensional substrates
We also specialize in advanced batch PVD coaters (RTEP- thermal evaporation, RTAC-cathodic arc coater, RTSP- magnetron sputtering coater, RTAS- arc+sputtering models) and ( R2R web vacuum metallizer )roll-to-roll processes that require precision deposition, tension, and uniformity. Additionally, we offer equipment and technology specifically designed for medical instrumentation and bio-compatible coatings except decorative coatings.s are machines utilized by the manufacturing industry to produce thin, uniform layers of aluminum onto flexible substrates, such as plastic films, paper, foils, and textiles.
The technique used is a continuous roll-to-roll process, which offers high production speeds, excellent control over the aluminum layer, and efficient processing of a wide range of substrates.
The metallization process makes use of the following components: an Unwind Station, a Cleaning Section, a Pre-Treatment Section, a Metallization Chamber, a Cooling Section, and a Winding Station.
In summary, the substrate passes through a cleaning section to remove any impurities, then it goes through pre-treatment to improve adhesion. Finally, the substrate is sent to the metallization chamber, where the aluminum material is heated to its evaporation point, and a thin layer is then condensed onto the substrate, which then goes through a cooling section and a winding station to be ready for further processing or usage.
R2R web aluminum vacuum metallizers offer a plethora of advantages compared to other metallization techniques and are essential for creating functional and decorative coatings on materials. Note, however, that details and features of these machines may vary depending on the manufacturer and its intended application.
The RT-R2R Web Aluminum Vacuum Metallizer is a great choice for high throughput at a low cost. It provides a heavy deposition layer for higher barrier applications and free-span processes which eliminates the need for a drum line and edge trim.
The metallizer is user friendly with its low tension substrates like CPP, BOPP and LDPE.
Individual wire feeds gives simply easy maintenance while precision web handling mechanism with Servo motor drives provides accurate control regardless of the line speed. Its compact design also makes easy installations with minimal floor space.
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:
The process begins with a roll of the flexible substrate material, which is unwound and fed into the metallizing machine. This may be followed by a cleaning section for surface contaminants and/or pre-treatment processes such as corona treatment or primer application. The substrate then enters the metallization chamber which is a high vacuum and consists of evaporation sources or cathodes containing the metal to be deposited. After being heated to its evaporation point, the metal vaporizes and forms a thin coating layer on the substrate, before passing through a cooling section and winding onto a roll.
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 a number of advantages, such as high production speeds, precise control over coating thickness, excellent adhesion, and the ability to process a wide range of flexible substrates. It is for these reasons that this technique is used in various industries such as packaging, electronics, automotive, and more.
Vacuum Web (Roll) Coating is a popular process in the industry, utilizing Roll-to-Roll (R2R) web vacuum metallizing equipment for various applications. The process involves coating a thin, flexible web, in the form of a roll, which can be as wide as 10 feet and weigh thousands of pounds. It can be wrapped around a thermal evaporation system before undergoing the coating process, which can take place at a speed of up 2000~3000fpm (feet-per-minute).
R2R web vacuum metallizing equipment is used for many purposes, primarily related to packaging, decorative applications, reflective coatings, electronics, solar energy, and anti-counterfeiting. Packaging materials, such as snack bags, candy wrappers, and pouches, can be given a glossy, metallic appearance with improved barrier properties. Decorative elements, such as plastic components, trims, nameplates and others, can be finessed with a metallic finish for an attractive appearance. Reflective coatings can also be produced for mirrors, reflective films, and reflector surfaces for lighting fixtures. Finally, metallized films can be employed for electronics in the form of touchscreens, flexible circuits, electronic components and printed circuit boards (PCBs), as well as solar power plants. In addition, metallize coatings can be used for security features, such as anti-counterfeiting measures for labels and packaging.
The versatility of R2R web vacuum metallizing equipment make it suitable for a wide range of purposes in the industry, providing flexible substrates with functional and decorative coatings.
