HWF100-10NH type atmosphere sintering furnace, made in China

Model: HWF100-10NH

Designed for medium-temperature heat treatment of electronic products, including electronic ceramics, dielectric materials, and conductors, under nitrogen/hydrogen protective atmospheres.

• Energy Efficiency: Equipped with FEC ceramic fiber heaters for fast heating, excellent thermal insulation, and low energy consumption.
• High-Precision Temperature Control: 3 independent control zones + 9 programmable segments enable precise temperature management with stability of ±1°C and uniformity better than ±5°C, meeting demanding process requirements.
• Protective Atmosphere Compatibility: Supports nitrogen/hydrogen atmospheres, ideal for heat treatment of oxidation-sensitive materials, enhancing product performance and quality.
• Intelligent Control System: Utilizes Yokogawa (Japan) intelligent temperature controller integrated with PLC and touchscreen interface, offering easy operation and PID auto-tuning for complex process profiles.
• Safety and Reliability: Multiple protection features including over-temperature and thermocouple breakage alarms, audio-visual alerts, and automatic power cut-off for enhanced operational safety.
• Robust Design: Compact furnace chamber suitable for small to medium batch production; low surface temperature rise ensures safe handling and reduced external heat emission.

• Sintering of electronic ceramics
• Heat treatment of dielectric materials
• Hydrogen/nitrogen-protected annealing of conductive materials
• Atmosphere-controlled heat treatment processes (e.g., reduction, inert atmosphere protection, etc.)

• Power supply - capacity greater than 40KVA, 3-phase 5-wire, 220/380VAC, 50Hz.
• Nitrogen - high-purity nitrogen with a purity of 99.999%, operating pressure of 0.2-0.4 MPa, and a supply flow rate of 2-6 m3/h.
• Hydrogen - Pressure: 0.1 to 0.3 MPa, Supply Flow: 2 to 6 m3/h.
• Cooling water - clean and non-corrosive, water temperature below 25°C, supply flow rate ≥ 0.5m3/h, customers need to use open water return system.

• The device must be installed indoors, in an environment with a temperature range of 0°C to 40°C, and free from flammable gases, corrosive gases, and steam.
