Vacuum Metallizing Capabilities and Equipment
Deep Coat runs eight metallizing chambers and two deposition processes — patented Quad-Fire (up to four metal layers per draw) and Dual-Fire (up to two) — across six production metals, matching a coating to almost any requirement from a decorative finish to a multi-layer conductive shield.
Capabilities are not just equipment — they are how the steps connect. Because Deep Coat thermoforms, masks, metallizes, and finishes in-house, the same partner that controls part geometry also engineers and applies its shield, keeping performance repeatable.
Deposition Processes
- Quad-Fire (patented) — up to four metal layers in one draw; combine conductivity, corrosion resistance, and a groundable surface without secondary operations.
- Dual-Fire — up to two metal layers for tuned performance at lower complexity.
Production Metals
Deep Coat deposits six production metals, each chosen for the property a design needs most:
| Metal | Chosen for |
|---|---|
| Copper | highest conductivity → maximum RF / high-frequency shielding. |
| Aluminum | strong conductivity at low cost → general-purpose, high-volume, reflective. |
| Tin | solderable, corrosion-resistant → grounded / solderable contacts. |
| Nickel | conductive and corrosion-resistant → low-frequency shielding, environmental barrier. |
| Nickel/Chrome | wear- and corrosion-resistant → ruggedized, frequently handled parts. |
| Stainless steel | robust, corrosion-resistant → demanding defense and industrial service. |
Quality and Compliance
- ISO 9001:2015 — quality management across all production stages.
- Processing aligned to RoHS, REACH, UL, and WEEE requirements.
- Shielding performance — engineered to your target and confirmed by your accredited test lab; results are enclosure-specific.
Frequently Asked Questions
What is the Quad-Fire process?
Quad-Fire is Deep Coat’s patented vacuum-metallizing process that deposits up to four metal layers in a single draw — letting one part combine, for example, a high-conductivity shield with a durable, groundable surface.
How many metals can Deep Coat deposit?
Six production metals: aluminum, copper, tin, nickel, nickel/chrome, and stainless steel — which can be layered via Quad-Fire or Dual-Fire.
What size and type of parts can you coat?
Deep Coat coats thermoformed and molded plastic and composite parts across eight metallizing chambers, coating complex three-dimensional geometry uniformly. Share your part for a capacity assessment.
