1.Vacuum Chamber Preparation: The chamber is evacuated to high vacuum to remove air and moisture.
2.Substrate Pre-Treatment: Metal workpieces are cleaned via ion bombardment and heated.
3.Sputtering Process: Argon gas is injected into the chamber; high voltage ionizes argon into plasma. Under the action of a strong magnetic field, plasma ions are accelerated to bombard the sputtering target, ejecting target atoms.
4.Coating Deposition: Target atoms uniformly deposit on the rotating metal workpieces, forming a dense, thin coating.
5.Cooling & Unloading: After coating, the chamber is vented; workpieces are cooled to room temperature and unloaded—ready for use or post-processing.
Exceptional Adhesion: Adopts metal substrate pre-treatment to ensure coating-substrate bonding strength reaches ASTM 5B level. Even for high-hardness metals, the coating remains intact after 10,000+ times of friction testing.
Extreme Durability: Supports deposition of wear-resistant coatings with surface hardness up to HV 4000—3x harder than traditional electroplated chromium. Metal tools coated with TiAlN can extend service life by 5–10x; auto engine parts can withstand 500°C high temperatures without coating degradation.
Strong Corrosion Resistance: Ceramic-based coatings and nitride coatings enable metal parts to pass 2,000-hour neutral salt spray testing—ideal for marine, automotive, and outdoor metal components.
Fast Deposition Rate: Equipped with high-power magnetron targets and optimized magnetic field design, deposition rate reaches 300–800 nm/min—2–4x faster than conventional PVD machines. For thin decorative coatings (50–200 nm), a single batch of metal parts can be coated in 15–30 minutes.
High Target Utilization: Closed-field unbalanced magnetron structure increases target material utilization from 15% (traditional) to 45%, reducing raw material waste. For high-cost metal targets, this cuts annual target consumption costs by 30%.
Large Batch Capacity: Configurable planetary workpiece racks can hold metal parts of various sizes—from small screws to large auto wheels. Single-batch capacity ranges from 100–500 pieces, meeting industrial-scale output.
Fully adapts to all common metal substrates, solving the problem of "poor coating adaptability for special metals":
Ferrous Metals: Stainless steel, carbon steel, cast iron.
Non-Ferrous Metals: Aluminum alloy, titanium alloy, copper alloy, magnesium alloy .
Special Metals: Tungsten, molybdenum, nickel-based superalloys .
Intelligent Process Management: 12-inch touchscreen HMI with 200+ customizable process recipes. Parameters like vacuum level, sputtering power, gas flow, and coating thickness are automatically controlled, reducing human error to <0.5%.
Real-Time Quality Monitoring: Built-in film thickness sensor and vacuum leak detection system. If parameters deviate, the machine triggers an alarm and pauses operation—ensuring consistent coating quality for each batch of metal parts.
24/7 Continuous Operation: Robust vacuum system and wear-resistant target holders enable stable operation for 3,000+ hours without major maintenance—matching the high-load production rhythm of metal factories.
Zero Pollution: Pure physical deposition process—no cyanide, heavy metals, or volatile organic compounds (VOCs) emitted. Complies with EU RoHS, REACH, and Chinese GB 21900 environmental standards, helping metal enterprises avoid environmental penalties.
Energy-Saving Design: Adopts DC pulse sputtering technology and heat recovery system, energy consumption is 40% lower than electroplating machines and 25% lower than thermal evaporation PVD machines. For a 2-shift daily operation, it saves ~300 kWh of electricity monthly.
