What Is Vacuum Metallization And Why Is It Important? | Vacuum Metallization Services | Functional Coatings | Mueller Corporation

Vacuum metallization is a common practice in the manufacturing industry. Parts of all types and uses are commonly coated with metal for a variety of reasons. More than just making a part look visually pleasing, vacuum metallization can also offer physical protection against damage. 

Mueller offers UV vacuum metallization services for a wide variety of parts. But, what exactly is vacuum metallization and how does it work? 

What is vacuum metallization? 

Having a part vacuum metalized involves the process of applying a metal coating over the part. The metal coating is applied within a vacuum-sealed area and coats the entire part evenly. This coating provides a variety of benefits, both visual and physical. 

Many device components and plastic parts require vacuum metallization to ensure the proper function of the device. Without the proper coating at the proper thickness, the parts can take on damage and the device can fail to function properly. With a suitable coating made of the right metal, these essential parts can last for years. 

What are the benefits of vacuum metallization? 

There are many different reasons a company may need their component parts vacuum metalized, including: 

  • Adding reflective properties to a part- Some parts need to have a reflective surface for aesthetic purposes or proper function of a device. 
  • Protection against oxygen and moisture Many component parts must be protected from liquids and oxygen in order to avoid damage and failure. 
  • Creating or limiting electrical conductivity Depending on the part, a device may need to enhance or limit the amount of electricity passing through. Proper vacuum metallization can help control the flow of electricity. 

Metals such as aluminum, copper, and nickel can be used in the vacuum metallization process. Each metal provides its own benefits, both physically and aesthetically. Understanding the function of the part is essential before choosing the metal that will be used for coating. 

How is vacuum metallization performed? 

Mueller provides UV vacuum metallization services for any essential parts that require it. Combining liquid spray and metallization, our process creates both physical and aesthetic benefits for the parts. 

Our process involves applying a UV-cured primer to ensure proper adhesion. A vaporized metal is then applied to the part’s surface inside a vacuum. Finally, a durable UV clearcoat or tinted coat is added for protection and visual appeal. 

This physical vapor deposition (PVD) process ensures a complete coating of the part with an even amount of metal. With an even coating, the part will be well-equipped to handle the stress of device operation, be it heat, grinding, cutting, or friction. 

Vacuum metallization provides a protective barrier against damage for any device part. It also offers a beautiful finish for parts that will be featured on the exterior of a device. The process is easy and effective, providing a variety of benefits for both manufacturers and consumers.
