Structure and Specifications
This high-precision decorative coating system is specifically designed for the mass production of premium 3C product housings, mobile phone casings, smartwatches, eyeglass frames, and decorative hardware components. It adopts a vertical front-opening structure with a well-organized internal layout, offering convenient loading and maintenance operations. The system ensures excellent sealing performance and thermal stability, maintaining uniform temperature and a stable vacuum environment throughout long deposition cycles. As a result, the coatings achieve consistent color tone, strong adhesion, and a smooth metallic finish.
Coating Process and Configuration
The equipment integrates multiple coating technologies—combining magnetron sputtering and cathodic arc deposition—to achieve high-adhesion, high-density decorative coatings. The core process configuration includes:
Mid-Frequency Cylindrical Magnetron Sputtering System: Provides a uniform deposition rate suitable for large-area, precision components requiring high-quality coatings.
Ion Source System: Performs substrate surface cleaning and enhances coating adhesion, improving film compactness and surface smoothness.
Cathodic Arc Pre-Coating Process: Forms a high-energy base layer prior to deposition, ensuring strong bonding between the metallic coating and the substrate while enhancing corrosion resistance and overall durability.
Vacuum System
The system features a high-performance vacuum pumping unit capable of rapidly achieving and maintaining high vacuum conditions. This prevents oxidation and contamination during deposition, ensuring coating purity and color stability. The automated vacuum control platform supports precise pressure regulation, flow adjustment, and process monitoring throughout each deposition stage.
Performance Parameters
Coating thickness range: 0.3–1.5 μm
Excellent coating adhesion and surface smoothness
High resistance to wear, corrosion, and oxidation
Stable color tone with strong metallic luster
Long-term color stability with anti-fingerprint performance
Depositable Materials and Color Options
The system supports the deposition of a wide range of decorative metallic compound coatings, including:
TiN – gold color
CrN – silver-gray color
ZrN – champagne gold color
