Magnetron Sputtering PVD Vacuum Deposition Machine System for Plastic

1. Core Value: Addressing Key Pain Points of Plastic Substrates

1. Performance Enhancement: After coating, the surface hardness of plastics increases to 2-6H (depending on the target material), enabling scratch resistance and fingerprint resistance. It also enhances weather resistance (UV resistance, moisture and heat resistance) and chemical corrosion resistance (solvent resistance, sweat resistance).

2. Appearance Upgrading: It can achieve metallic textures (e.g., aluminum, chrome, titanium colors), colorful effects (e.g., gold, gunmetal gray, blue), or transparent conductive layers, meeting the demand for high-end appearances in industries such as 3C and automotive.

3. Environmental Compliance: Compared with traditional electroplating, it has no heavy metal (e.g., hexavalent chromium) emissions and extremely low VOCs emissions. It complies with international environmental standards such as RoHS and REACH, reducing environmental treatment costs.

2. Core Technology: Magnetron Sputtering Principle Adapted for Plastics

1. Vacuum Environment Construction: The ultimate vacuum degree of the vacuum chamber can reach 5×10⁻⁴Pa, eliminating air impurities and ensuring film purity and adhesion.

2. Low-Temperature Sputtering Design: By adjusting the sputtering power and target-substrate distance, the substrate temperature is controlled at 60-120°C to avoid plastic deformation or aging.

3. Multi-Target Compatibility: It supports metal targets (aluminum, chromium, titanium), alloy targets (stainless steel color), and compound targets (ITO transparent conductive layer, TiO₂ wear-resistant layer), enabling single-layer or multi-layer composite coating.

4. Substrate Pretreatment: Some models integrate a plasma cleaning module to remove oil and impurities from the plastic surface, improving film adhesion (peel strength ≥5N/25mm).

3. Typical Application Fields

• 3C Electronics: Metallic texture coating for mobile phone cases, earphone shells, and smart watch straps, or ITO conductive layers for transparent buttons.
• Automotive Industry: Wear-resistant decorative coating for automotive interior parts (e.g., air vents, steering wheel trim) and exterior parts (e.g., door handles).
• Packaging Industry: Barrier layer coating (e.g., aluminum layer) for PET and PP films used in food/cosmetics packaging to extend product shelf life.
• Medical Devices: Antibacterial and corrosion-resistant coating for plastic medical devices (e.g., syringe casings).
