Hardware Mold Tunnel Furnace Drying Line
The 9-Meter Hardware Mold Tunnel Furnace Drying Line is a high-efficiency continuous heat treatment system specially designed for industrial hardware components and large-scale molds. The equipment adopts a tunnel-type structure combined with an automated conveying system, enabling workpieces to achieve uniform heat transfer while continuously passing through the heating zones. It is widely used for large-batch, standardized production line drying and curing processes.
Applications
Coating Curing:
Used for high-temperature baking and curing of surface coatings on hardware molds, including spray painting, powder coating, and PTFE coating treatments.
Moisture Drying:
Used for rapid dehydration and drying of hardware components after cleaning, electroplating, pickling, degreasing, and other processes.
Stress Relief and Hydrogen Removal:
Used for gentle low-temperature heat treatment of molds after machining or electroplating to eliminate internal residual stress and reduce hydrogen embrittlement risks.
Preheating Treatment:
Used for preheating large hardware molds before welding, assembly, or rubber coating processes.

Features
Uniform Heating:
Adopts multi-zone independent air circulation design combined with powerful circulation fans to ensure no dead zones inside the furnace and maintain minimal temperature differences.
High Efficiency and Energy Saving:
The furnace body uses high-density rock wool insulation with a thickness of 100–150 mm, effectively reducing heat loss and improving energy efficiency.
Intelligent Control:
Equipped with PLC touch screen and intelligent temperature controllers, supporting temperature curve recording, process monitoring, and over-temperature alarms.
Strong Load-Bearing Capacity:
The conveying system is specially reinforced for heavy hardware molds, ensuring stable operation without jamming under high-load conditions.
Comprehensive Safety Protection:
Equipped with multiple safety mechanisms, including leakage protection, motor overload protection, abnormal over-temperature power-off protection, and other safety functions.
