In modern high-precision manufacturing, sliding mechanisms, plastic molds, and non-ferrous metal forming dies face intense operational stress. Standard hard coatings often fail to provide sufficient lubrication, leading to severe adhesive wear, material sticking, and high friction.

To overcome these extreme tribological challenges, Jiangsu Juchuang Automation Technology Co., Ltd. engineered the E-ACT High-Frequency Pulsed Sputtering PVD / PACVD (DLC) Equipment. As our premier hybrid deposition platform, the E-ACT series integrates advanced high-frequency magnetron sputtering with Plasma-Assisted Chemical Vapor Deposition (PACVD). This system is designed specifically to deposit high-performance Diamond-Like Carbon (DLC) and advanced carbon-based composite coatings, delivering a glass-smooth surface with an ultra-low friction coefficient.

1. Core Technical Strengths

The E-ACT system represents a major leap forward in low-temperature vacuum coating technology, offering five core operational advantages:

Strong Coating Adhesion

Historically, DLC coatings suffered from internal stress, leading to delamination on steel substrates. The E-ACT series utilizes high-energy pulsed ion cleaning and advanced gradient layer transition designs to secure an exceptionally strong atomic bond between the substrate and the outer carbon layer.

High Coating Density

By combining high-frequency pulsed power supplies with proprietary magnetic field arrangements, the system significantly boosts the gas ionization rate. This creates highly dense, defect-free coatings that provide superb protection against micro-abrasion and oxidation.

Extreme Low Friction Coefficient

The deposited DLC layers feature a dry lubrication effect, dropping the friction coefficient to less than 0.1. This drastically reduces mechanical drag and prevents sliding components from sticking or seizing during operation.

Outstanding Anti-Sticking and Anti-Corrosion Properties

The carbon-based structure is highly inert, preventing cold-welding and adhesive material transfer (such as aluminum or copper sticking to mold surfaces). Additionally, it forms an outstanding barrier against chemical attack and acidic plastic outgassing.

Stable Performance Under Extreme Workloads

Even under high speed, high load, and dry running conditions, the E-ACT coatings preserve their high surface hardness and structural integrity. This guarantees long-term operational stability for your production lines.

2. Diverse Industrial Application Scenarios

The E-ACT PVD/PACVD system is the ideal choice for high-yield job shops, automotive suppliers, and precision tooling manufacturers:

• Aluminum and Non-Ferrous Stamping Molds: Prevents material dragging and cold-welding on high-speed punching, drawing, and forming dies for aluminum, copper, and zinc alloys.

• Precision Plastic and Injection Molds: Protects mirror-finish core pins and ejector sleeves, ensuring easy part release without the need for toxic liquid release agents.

• Rubber Mold Manufacturing: Extends the working life of complex rubber compression molds by preventing polymer residue buildup and easing the cleaning cycle.

• Critical Sliding Mechanical Parts: Minimizes friction and wear on heavy-duty engine valvetrains, hydraulic piston rods, precision pump impellers, and robot joint transmission gears.

3. Key Technical Specifications and Parameters

Every E-ACT system is engineered with high-precision vacuum controls and smart power supplies to guarantee repeatable, batch-to-batch consistency:

• Effective Vacuum Chamber Size: Diameter of 930 mm by a height of 1000 mm. This spacious vertical configuration is optimized for bulk batches of automotive parts and large plastic molds.

• Maximum Loading Capacity: Supports up to 800 kg of workpieces on a heavy-duty rotating carousel.

• Coating Batch Cycle Time: Approximately 5 hours per batch, delivering rapid turnaround times for high-volume contract coating shops.

• Deposition System Technology: High-frequency pulsed magnetron sputtering coupled with high-efficiency PACVD, running our proprietary control software for automated process execution.

4. Hardware Integration and Layout

The physical architecture of the E-ACT system is built for industrial durability and space efficiency. The equipment features a fully integrated, dual-cabinet design:

• Left-Side Processing Zone: Comprises the main cylindrical vacuum chamber with a highly automated vertical door. This configuration allows for quick crane-loading of heavy mold blocks up to 800 kg.

• Right-Side Power and Gas Cabinet: Houses the proprietary high-frequency pulsed generators, high-precision Mass Flow Controllers (MFCs) for process gases, and the centralized PLC cabinet.

• Central Control Terminal: Features an interactive industrial touch screen running Juchuang's intelligent software, displaying real-time pressure, temperature, and plasma discharge curves.
