VDI

The Highest Quality Services and Capabilities

No other controlled-density vacuum coater offers the range of capabilities VDI offers from one location. Give us a call and let's talk about how we can solve your challenges.

VDI Capabilities

 

VDI offers three state-of-the-art metallization processes at its Louisville location – evaporative deposition, sputtered deposition and electron-beam deposition.

Evaporative Deposition

VDI offers Evaporation / Vapor and web widths of 80 inches and thicknesses of 10 mil to 36GA (9 micron). Substrates include PET, Nylon, other web polymers, fabrics, and foils.

Aluminum vapor deposition capabilities range from 100 to 4,000 Angstroms, from 0.15 to 4.0 optical density, 70% visible light transmission to opaque, and resistance to meet varied needs.

In evaporative deposition, a source material is heated with a resistant source and since the chamber is under high vacuum, the material evaporates, traveling in all directions and lands on the substrate that is moving over it.

VDI’s capabilities enable it to provide tight tolerances and uniformity of metal deposition, cross web, down-web, and roll-to-roll. In addition, our plasma treatment ensures improved metal adhesion in films.

Sputtered Deposition

VDI has sputtering capabilities from web widths of 80 inches to .5” (12mm), and thicknesses of 1mm to 36GA (9 micron). Substrates include PET, Nylon, other web polymers, fabrics, foils, and flexible glass.

VDI sputters a variety of metals, alloys, dielectrics and transparent conducting oxides. Metals include silver, copper, chrome, titanium and others. Alloys include nichrome, inconnel, and stainless steel. Dielectric materials include silicon dioxide (SiO2), titanium oxide (TiO2) and titanium nitride (TiN). Transparent conductive oxides include indium tin oxide (ITO) and aluminum zinc oxide (AZO).

Sputtering is a process where a target is electrically charged and bombarded with a process gas such as argon. This generates a plasma, which deposits the target material onto the surface of the substrate. Metals can be sputtered, and in some cases, reactive sputtering can be achieved with materials that produce various oxides. Sputtering produces high quality films with exceptionally precise uniformity and functionality.

Electron-Beam Deposition

VDI has electron-beam deposition capabilities from web widths of up to 80 inches, and thicknesses of 10 mil to 36GA (9 micron). Substrates include PET, Nylon, other web polymers, fabrics, and foils.

VDI can use electron-beam deposition to coat a variety of metals, alloys, and dielectrics. Metals include silver, copper, tin, titanium and others. Alloys include inconnel, and stainless steel. Dielectric materials include silicon dioxide (SiO2) and titanium dioxide (TiO2).

Electron-beam deposition is similar to evaporative deposition with the exception of how the material is heated. In electron-beam deposition a beam of electrons is produced from a tungsten filament that is charged with electricity, this beam of electrons is shaped or directed by powerful electromagnets. The electron-beam heats the material and like the evaporation, the source material deposits on the substrate.

Solution Coating & Laminating

With more than 40 years of precision coating and laminating, Madico®, a subsidiary of VDI’s parent company, Lintec Corp., is a world leader in coating, laminating, and converting of films in wide width, roll-to-roll format.

Our products are complex, multi-layered, and engineered to our customers’ precise specifications — and complete satisfaction.

From adhesive, heat seal, and scratch resistant coatings to superhydrophobic, anti-microbial and thin film deposition, superior coatings can be achieved through Madico’s range of manufacturing capabilities.

Slitting

VDI offers customized slitting and rewinding both pre- and post-metallization. Our slitting machines can handle up to 80-inch-wide master rolls and we can cut to a minimum cut width of 4 inches.

Slitting involves cutting down a coil of material into smaller, narrower coils. It’s a highly productive process that can manage a wide variety of materials. Rewind slitting is a process where materials are brought through an array of knives – forming narrower rolls of materials.
