9-Meter 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.

Product 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.

Product Parameters

Product 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.

FAQ

Q1: What is the maximum heating temperature of this 9-meter tunnel furnace?

A1: The standard model has a maximum working temperature of 300℃. If your hardware molds require higher-temperature processes, customized models with temperatures up to 500℃ can be provided.

Q2: Will the conveyor system become stuck or deformed when carrying large and heavy hardware molds?

A2: No. This equipment is specially designed for heavy-duty hardware applications. The conveying system uses reinforced chains or thickened stainless steel mesh belts, with enhanced load-bearing structures to ensure stable operation under heavy loads.

Q3: How is the energy consumption of the equipment? Are there any energy-saving designs?

A3: The equipment uses a microcomputer PID automatic heating power adjustment system. After reaching the preset temperature, it automatically enters a low-power heat preservation mode. Combined with the 100–150 mm thick thermal insulation layer, it significantly reduces energy consumption.

Q4: Does the 9-meter length include the cooling section? Can the length of each section be adjusted freely?

A4: The 9-meter length refers to the total equipment length. The proportions of the feeding section, heating section, constant temperature section, and cooling section can be fully customized according to product process requirements, heating time, and factory layout.

Q5: How should the equipment be maintained during daily operation?

A5: Regularly clean debris inside the furnace and on the conveyor system. High-temperature lubricating oil should be applied to the transmission chain and high-temperature bearings every 1–3 months. Regular inspection of heating tube connections and temperature sensor wiring is also required to ensure reliable operation.
