In heavy-duty machinery, wind power generation, marine engineering, and aerospace manufacturing, components are getting larger, heavier, and more complex. Consequently, hardening these massive parts without causing thermal warping or bending is a major challenge for factory managers.
To solve this problem, Jiangsu Juchuang Automation Technology Co., Ltd. engineered the E-MAX Large Horizontal High-Frequency Pulsed Plasma Nitriding Furnace. As our flagship vacuum thermal processing system, the E-MAX is built specifically for ultra-large, high-precision steel parts. It combines massive power, high heating efficiency, and unmatched temperature uniformity to deliver zero-deformation surface hardening.
Key Technical Strengths of the E-MAX Series
The E-MAX horizontal system is a major leap forward in vacuum surface engineering, offering four core technical advantages:
1. Ultra-High Power Pulsed Power Supply
At the heart of the system is our proprietary high-frequency pulsed power supply. Running at a frequency of 20 kHz with a maximum power output of 800 kW, this advanced power unit quickly ionizes nitrogen gas. It delivers a stable, intense plasma field that wraps evenly around complex geometries, preventing localized edge burns and ensuring uniform hardness.
2. Energy-Saving Insulated Furnace Body
Heating a massive vacuum furnace can consume a lot of electricity. Therefore, the E-MAX features a highly optimized thermal insulation structure. By improving internal gas circulation and heat retention, this design saves up to 25% in electricity consumption and speeds up temperature ramp-up times by 30%. Consequently, your workshop can lower its operating costs while running more batches per day.
3. Flexible Direct Temperature Measurement
Traditional nitriding systems often measure the air inside the chamber rather than the actual part. In contrast, the E-MAX utilizes flexible thermocouple sensors that attach directly to the workpieces. This direct feedback allows our intelligent control system to adjust heating elements in real time, maintaining a highly uniform temperature distribution of ±5°C across the entire hot zone.
4. Intelligent Process & Rapid Cooling System
The E-MAX furnace is managed by our advanced DLV-Control system, allowing operators to execute complex cycles with a single button. It fully supports specialized processes, such as mirror-finish nitriding and textured mold nitriding, preserving the original surface shine without requiring post-heat polishing. In addition, the active cooling design improves cooling speeds by over 50%, shortening the overall turnaround time.
