Product Overview


This continuous thermal processing system represents a significant advancement in pilot-scale manufacturing and industrial R&D. By utilizing a mesh-type conveyor belt design, the equipment transitions materials through seven independently controlled heating zones, allowing for precise thermal profiling that batch furnaces cannot replicate. It is engineered for the continuous production of electronic components, thick film firing, and advanced sintering of ceramic and metallic materials, providing a seamless bridge between laboratory research and full-scale industrial production.
The system is designed to provide a highly controlled atmosphere, making it ideal for processes requiring protective gases or specific chemical reactions. Target industries include the photovoltaic sector for cell metallization, microelectronics for component fabrication, and advanced materials engineering for the purification and calcination of specialized powders. The robustness of the mesh belt, combined with the modular heating architecture, ensures that this unit remains a versatile asset in high-throughput environments where consistency and uptime are critical metrics.
Built with premium thermal components and high-purity insulating materials, the equipment offers exceptional reliability under demanding conditions. The integration of dual-layer insulation and forced cooling ensures both energy efficiency and operator safety, maintaining a low external casing temperature even during peak operation. By utilizing high-grade heating elements and a redundant thermocouple monitoring system, the unit delivers the repeatable performance necessary for the most rigorous material science protocols and quality-controlled industrial workflows.
Key Features
- Seven Independent Heating Zones: The furnace features a total heating length of 2100mm divided into seven discrete modules. Each 300mm zone is independently controlled, allowing for the creation of complex temperature ramps and soak profiles required for multi-stage chemical reactions or controlled sintering processes.
- Precision Atmosphere Management: This equipment is engineered to handle protective gas atmospheres, facilitating gas-solid reactions, purification, and carbonization. The entrance and exit configurations are designed to maintain internal environment stability, ensuring consistent results for sensitive photovoltaic and semiconductor applications.
- Premium Thermal Elements: Utilizing genuine Kanthal heating wire and Omega thermocouples, the system guarantees long-term durability and accurate thermal transfer. These high-end components are selected for their resistance to oxidative stress and their ability to maintain precise thermal gradients across the entire processing path.
- Advanced Dual-Thermocouple Monitoring: The system employs 15 individual K-type thermocouples—7 dedicated to precise PID control and 8 dedicated to real-time temperature monitoring. This redundancy ensures that any thermal drift is detected immediately, providing an extra layer of security for high-value industrial batches.
- Energy-Efficient Multi-Layer Insulation: High-purity fibrous alumina insulation is utilized between each heating module to minimize heat loss and cross-zone thermal interference. A dual-layer insulation design further ensures that the exterior casing remains below 70°C, enhancing safety and reducing the cooling load on the laboratory environment.
- Intelligent Touchscreen Control: A centralized large-format touchscreen interface provides a comprehensive overview of all seven zones. Users can program individual profiles, monitor real-time data, and manage the conveyor speed from a single remote-operable control unit, streamlining the operation of complex thermal cycles.
- Durable Mesh Conveyor System: The 130mm wide mesh belt is supported by a series of high-quality quartz supports throughout the furnace interior. This design prevents belt sagging and reduces friction, ensuring smooth movement of workpieces and extending the operational lifespan of the drive mechanism.
- Integrated Cooling Section: A 300mm long cooling zone is integrated at the furnace discharge. This allow for the controlled reduction of material temperature before unloading, which is essential for preventing thermal shock in ceramics and ensuring the structural integrity of metallized electronic components.
- Modular and Customizable Architecture: The modular design allows for the heating models to be adapted to specific production needs. While the standard configuration offers 2100mm of heating length, the system can be customized from 300mm to 2100mm, with options to increase the belt width up to 12 inches for larger throughput requirements.
