Evaporation Plastic Metallizing Vacuum Coating Machine Nickel Chrome Plating PVD Coating Machine

I. Core Functions & Process Principles

1. Types of Evaporation Sources

• Resistance Heating: Suitable for low-melting-point metals (e.g., Al, Ag, Ni, Cr). It uses tungsten or molybdenum boats heated by electric current to vaporize materials. The equipment has low costs and simple operation, making it ideal for small-to-medium batch production.
• Electron Beam Heating: Utilizes high-energy electron beams to bombard metal targets. It can evaporate high-melting-point materials (e.g., W, Ta, Mo) and produce films with high purity (99.9%-99.99%) and high thermal efficiency. It is suitable for manufacturing high-precision optical films or functional films.

2. Process Advantages

• High-Purity Coating: The vacuum environment (ultimate vacuum ≤ 5×10⁻⁴ Pa) prevents oxidation and impurity contamination. It is particularly suitable for optical films with high purity requirements (e.g., anti-reflective (AR) films, optical filters).
• Rapid Deposition: The metal evaporation rate can reach 50-500 nm/min, significantly enhancing production efficiency. It is suitable for decorative coating (e.g., metal-like appearance).
• Broad Substrate Compatibility: Supports non-metallic substrates such as plastics (ABS, PC, PP), glass, and ceramics, as well as some metallic substrates.

III. Typical Application Fields

1. Consumer Electronics & Decoration

• Mobile Phone/Tablet Casings: Nickel, chromium, aluminum, or other metal films are coated to achieve mirror effects or metallic textures, enhancing product quality.
• Smart Home Accessories: Bathroom hardware (faucets, door handles) and furniture trim strips are coated with nickel-chromium alloys. This replaces traditional electroplating, offering both aesthetics and rust resistance.
• Crafts & Packaging: Ceramics and glass surfaces are coated with aluminum or gold-like films for gifts and cosmetic packaging, enhancing visual appeal.

2. Optical & Functional Films

• Optical Lenses: Dielectric films such as silicon dioxide (SiO₂) and titanium oxide (TiO₂) are coated to achieve anti-reflective, reflective, or light-filtering functions. They are used in camera lenses and eyeglass lenses.
• Solar Cells: Silver or aluminum electrodes are evaporated onto glass or flexible substrates to improve photoelectric conversion efficiency, with material utilization rates exceeding 90%.
• Anti-Counterfeiting Labels: Multi-layer metal-dielectric film designs are used to create photochromic anti-counterfeiting effects, supporting traceability of high-end products.

3. Automotive & Industrial Sectors

• Automotive Headlight Reflectors: Aluminum films are coated to achieve a reflectivity of ≥95%, enhancing lighting effects. Plasma-assisted coating (optional) improves weather resistance.
• Plastic Automotive Trim: Instrument panels and air conditioning vents are coated with nickel-chromium, replacing electroplating to reduce production costs and pollution.
• Metallized Films: Aluminum layers are evaporated onto PET or PC films for use in electromagnetic shielding materials or flexible electronic devices.
