Vertical Plasma Nitriding Furnace｜47% Faster Heating & Cooling for Uniform Surface Hardening
DOWA Thermotech’s Vertical Plasma Nitriding Furnace delivers 47% improved heating and cooling efficiency, with precise temperature zone control for uniform nitriding ideal for complex-shaped automotive, aerospace, and precision parts. This furnace minimizes arcing by suppressing glow discharge from room temperature and improves energy savings by 20% with reflector-based insulation. Its vertical design supports mixed processing of parts with varied shapes and weights.
Key Features:
- Arc Suppression: Stable plasma discharge without premature glow from room temperature
- Uniform Processing: Multi-zone temperature control for even surface hardening
- Efficiency Boost: 47% improvement in thermal processing vs. previous models
- Energy Saving: Reflective insulation cuts energy use by approx. 20%
- Flexible Loading: Supports simultaneous treatment of varied part shapes
- Rapid Cooling: In-furnace fan + heat exchanger for faster cycle time
Technical Specifications:
- Vacuum Level: <60Pa (0.5 Torr)
- Temperature Range: 350 - 570°C (max 600°C)
- Effective Heating Sizes:
- DPN-5065: Φ500 × H650 mm
- DPN-9150: Φ900 × H1500 mm
- DPN-13200: Φ1300 × H2000 mm
- Max Load: 600 - 2000 kg (model dependent)
Applications:
- Automotive Parts: Gears, shafts, bearings requiring surface wear resistance
- Aerospace: Precision nitriding for lightweight and complex components
- Precision Machinery: Uniform hardening for high-tolerance metal parts
Why Choose This Furnace?
- Reduces processing time and energy consumption
- Ensures uniform treatment even for complex geometries
- Offers stable, arc-free plasma starting at low temperatures
- Ideal for multi-part, multi-shape processing in one cycle
The Vertical Plasma Nitriding Furnace is the smart choice for facilities aiming to combine high thermal performance, precision nitriding, and energy-efficient operation.
