UV Vacuum Metallization: Advanced Surface Finishing Technology

Lencolo 2025-09-15 7

In modern manufacturing, surface finishing is no longer just about aesthetics—it represents brand value, product durability, and overall performance. While traditional electroplating can deliver a metallic appearance, it often falls short in terms of environmental compliance, efficiency, and long-term stability. With stricter environmental regulations and rising consumer demand for premium finishes, UV Vacuum Metallization is rapidly becoming the preferred solution for high-end surface treatment.

Process Overview

UV Vacuum Metallization is an integrated surface finishing technology consisting of three key stages:

1.Vacuum Metallization

In a high-vacuum chamber, aluminum or other metals are evaporated and deposited onto the substrate, forming a dense and uniform metallic layer with excellent reflectivity and brilliance.

2.UV Coating Application

A specially formulated UV-curable coating is applied on top of the metal layer to provide both protective and decorative functions.

3.UV Curing

The coating is instantly cured under ultraviolet light, creating a highly crosslinked film with superior adhesion, scratch resistance, and chemical durability.

Technical Advantages

Environmentally Friendly: Free of heavy-metal electrolytes, low VOC emissions, fully compliant with RoHS and REACH regulations.

High Production Efficiency: UV curing completes within seconds, significantly reducing cycle times.

Versatile Finishes: Enables mirror-like metallization, matte effects, colorful coatings, and partial decorative designs.

Enhanced Performance: Delivers high surface hardness, wear resistance, weatherability, and chemical stability.

Application Fields

UV Vacuum Metallization is widely adopted across industries where both aesthetics and performance matter:

Consumer Electronics: Mobile phone housings, earphone parts, home appliance covers

Automotive Components: Interior trims, decorative strips, functional buttons

Cosmetic Packaging: Bottle caps, pumps, compact cases

Premium Home & Lighting: Lamps, furniture accessories, decorative pieces
