Vacuum metallizing is a physical process that produces a thin, uniform metallic coating on various materials, including plastic, glass, metal, and paper. The process involves vaporizing a metal plating material in a vacuum chamber, which then condenses on a workpiece to create a decorative or functional finish. The type of workpiece and coating material used can affect the thickness and appearance of the coating. Vacuum metallization is considered environmentally friendly and is used in a variety of applications, including toys, nameplates, models, and electronic devices.
Vacuum metallizing is a process that produces a shiny metallic finish on many materials. A metallic coating material and a workpiece are usually placed in a vacuum chamber. Within this chamber, the metal plating material is vaporized as the workpiece spins. The metal plating material condenses on the work piece to form a thin film that can be both decorative and functional. Workpiece and metal plating materials vary by application.
During the process, the metal plating material is often heated inside a vacuum chamber until it turns into a gas. Vaporized metal tends to stick to other materials and usually condenses on a workpiece as it cools. Compared to other methods of creating a similar coating, vacuum metallization is often considered more environmentally friendly. This is because the process is physical rather than chemical and produces little material waste.
In order for the metal coating material to create a consistent coating, a primer layer is often applied similar to the vacuum metallizing process. Requirements for coating thickness can vary depending on whether a piece is meant to be functional or decorative. Examples could include electronic coatings, which often require specific thicknesses and chrome-like finishes on toys. The workpiece and coating materials can also affect the thickness of the metal plating.
Materials that can benefit from using a vacuum metallizing machine include glass, plastic, metal, ceramic, and even paper. Plastic products often use the vacuum metallization process, as the plastic coating is often difficult to achieve through other processes. Whether decorative or functional, the materials that can receive a metallic foil can influence the metallic coating materials that can be used.
Aluminum is commonly used to create decorative pieces, although an additional protective finish is sometimes required to prevent dulling. Functional materials can also include aluminum, copper, nickel, lead and tin. Decoration materials could include platinum, titanium, gold and silver. Appearance and function depend on the type of facing material used. The application of these materials is often similar, however, as the same thin, uniform coating is desirable for many products.
Many products benefit from vacuum metallization. Toys, nameplates, and models might use vacuum metallization to create a range of chrome-like, sometimes colored, finishes. This chrome-like finish is often considered visually appealing, just like chrome metal. Additionally, vacuum metallization is often used to create protective or conductive finishes on electronic devices.
