Vacuum Deposition Coating Services — Thin Film Solutions

Vacuum deposition coating is a thin film application process performed in a vacuum chamber where material (typically aluminum or other metals) is vaporized and deposited onto substrates such as plastic, metal, or glass. The vacuum environment ensures superior adhesion, uniform coverage, and brilliant finishes. At Providence Metallizing, we use both thermal evaporation and advanced PVD methods to create decorative and functional coatings ranging from mirror-like metallic finishes to durable ceramic coatings like Titanium Nitride for industrial applications.

Vacuum plating (vacuum metallizing) and PVD (Physical Vapor Deposition) are related but distinct processes. Vacuum metallizing typically refers to thermal evaporation of aluminum in a vacuum chamber for decorative finishes. PVD encompasses advanced techniques like magnetron sputtering, reactive arc deposition, and RF methods that create highly durable functional coatings such as Titanium Nitride, Zirconium Nitride, and sputtered metals for EMI-RFI shielding. Providence Metallizing offers both processes, allowing us to select the optimal method for your specific application requirements.

The vacuum coating process at Providence Metallizing includes four key steps: Pre-treatment using advanced techniques to ensure coating adhesion on the substrate; Basecoat application using thermal or UV systems; Metallization where aluminum or other materials are evaporated or sputtered onto the part in vacuum chambers; and UV Topcoat to protect the metal layer and enable tinting to colors like gold, copper, or rose gold. This systematic approach delivers brilliant finishes with superior adhesion and durability for cosmetic, industrial, and architectural applications.

Providence Metallizing has 60+ years of experience coating a wide range of substrates including plastics (ABS, Polypropylene, PC/ABS, Ultem, Nylon, LCP, HDPE), metals (brass, steel, zinc, white metal, aluminum), and glass bottles and containers. Our advanced pre-treatment and plasma treatment capabilities allow us to successfully coat even difficult-to-adhere materials that other finishers cannot handle. We can match finishes across different substrate materials, critical for applications requiring metal and plastic components in the same assembly.

Lead times vary based on part complexity, finish requirements, and order volume. However, Providence Metallizing is known for fast turnaround, moving parts from sampling to production in half the normal industry lead times thanks to our in-house custom tooling design and build capability. Our 200,000+ sq.ft. facility operates 24-5 with capacity to process over a million parts per week. We offer free sampling services for most applications to establish process parameters before production runs begin.

We serve diverse industries including cosmetics and personal care (approved supplier to Estée Lauder, L'Oreal, Avon, Elizabeth Arden), jewelry manufacturing, automotive components, electronic and medical devices, plumbing and hardware finishes, lamp and lighting, architectural finishing, fragrance packaging, writing instruments, tableware, and hi-tech applications requiring EMI-RFI shielding. Our ability to produce over 30 different finishes on multiple substrate types makes us uniquely capable of meeting specialized requirements across these markets.

Yes, matching finishes on metal and plastic components is a core capability at Providence Metallizing. Our electroplating systems and vacuum metallizing processes can produce identical finishes including gold (14K-24K), silver, chrome, white bronze, brushed stainless, satin nickel, antique brass, and oil-rubbed bronze on both metal and plastic substrates. This is critical for electronic, medical, plumbing, and hardware industries where assemblies combine different materials but require a unified aesthetic appearance.

Absolutely. Providence Metallizing offers free sampling services for most customers and applications. We built our reputation on being amazingly responsive, able to move parts from sampling to production faster than competitors. Our separate in-house tooling design and build company adds capacity and efficiency, allowing us to create custom fixtures and processes tailored to your specific parts. This integrated approach ensures consistent results when transitioning from prototype samples to high-volume production runs.
