Structure and Specifications
The DLC-1112 series is a large-scale vacuum ion coating system designed for diamond-like carbon (DLC) and low-friction functional coatings. The chamber has an internal dimension of 1100 × 1200 mm (H) and an effective coating area of 900 × 900 mm (H), allowing simultaneous processing of multiple large components. The cylindrical chamber, combined with a dual-layer water-cooling system, provides precise temperature control and uniform heat distribution during deposition, ensuring film density and thickness uniformity. This design is particularly suitable for industrial components that demand exceptional wear resistance, hardness, and adhesion.

Ion Source and Process Configuration

The DLC-1112 series supports multiple ion source configurations to accommodate various DLC types (a-C, a-C:H, ta-C) and composite coating processes. Two standard models are available:

DLC-1112A

• Equipped with four anode-layer ion sources (1500 V / 10 kW each)

• Configured with four magnetron cathodes
  This setup generates high-energy ion beams capable of forming extremely dense and hard DLC films with superior adhesion, suitable for components requiring extreme hardness and wear resistance.

DLC-1112B

• Equipped with two anode ionization sources (10 kW each)

• Configured with four cylindrical magnetron targets
  This configuration balances hardness with toughness and adhesion, making it ideal for impact-resistant and wear-critical applications such as automotive components, cutting tools, and mold surfaces.

Power System Configuration

• Type A: Two magnetron power supplies + one single-pulse bias power supply

• Type B: Four magnetron power supplies (20 kW) + one single-pulse bias power supply
  The flexible power combination enables quick adaptation between high-hardness and high-toughness coating processes, ensuring optimal performance for diverse application requirements.

Vacuum and Control System
The system employs a high-performance turbomolecular pump group in combination with a mechanical backing pump, allowing rapid evacuation and stable high-vacuum conditions. This minimizes contamination and oxidation, ensuring film purity and consistency.
An intelligent fully automatic control platform manages key process parameters such as ion source power, bias voltage, gas ratio, and target power. Real-time monitoring and data recording functions enable full traceability and multi-recipe storage, ideal for continuous batch production.

Film Performance

• Type A: Coating hardness ≥3000 HV; thickness 2–3 μm; highly dense and extremely wear-resistant, ideal for high-load and high-friction environments.

• Type B: Coating hardness ≥2500–2800 HV; excellent toughness and impact resistance, suitable for precision molds and mechanical parts.

Application Fields
The DLC-1112 series is widely applicable across the following industries:

• Mold Surface Protection:
  For stamping, injection, and die-casting molds to enhance surface hardness, reduce wear and adhesion, and extend tool life.

• Cutting Tools:
  For turning tools, milling cutters, drills, and gear cutters to reduce cutting friction, increase speed, and improve stability.

• Mechanical Components:
  For bearings, piston rings, valves, and cams to minimize energy loss, reduce wear, and extend mechanical lifespan.

• Decorative Coatings:
  For watches, jewelry, and electronic casings, providing black, gray, or metallic DLC finishes that combine aesthetic appeal with durability.

By integrating anode-layer ion sources with magnetron sputtering technology, the DLC-1112 series enables flexible control of coating structure and performance to achieve high hardness, excellent adhesion, and outstanding tribological properties. With its large chamber, high-vacuum stability, and intelligent process control, the DLC-1112 is an ideal solution for producing premium-quality DLC coatings for molds, precision machinery, automotive parts, and high-end decorative applications.
