FAQ 

Q1: What types of adhesives can this tunnel furnace cure?

A: The equipment is widely applicable for thermal curing of common potting materials used in instrument manufacturing, including epoxy resin (EPOXY), silicone (SILICONE), polyurethane (PU), and other room-temperature or medium-temperature curing adhesives.

Q2: How does the equipment ensure temperature uniformity in different areas of the furnace?

A: The equipment is equipped with powerful circulation fans and specially designed air ducts to create uniform airflow inside the furnace. The temperature uniformity in the working area can be maintained within ±2℃.

Q3: Can the conveyor speed and temperature be adjusted simultaneously?

A: Yes. The PLC control system supports digital parameter setting. According to the potting thickness and curing requirements of different instruments, the optimal combination of heating temperature and conveyor speed can be adjusted automatically.

Q4: How is the safety of continuous operation guaranteed?

A: The equipment is equipped with an independent over-temperature power-off protection system, abnormal alarm buzzer, and transmission overload protection system, ensuring safe and reliable 24-hour continuous automated operation.

Q5: Can the length and width of the tunnel furnace be customized according to factory space?

A: Yes. All drying tunnel furnaces are customized products. The furnace dimensions, conveyor structure, temperature zones, and production configuration can be specially designed according to product size, production capacity requirements, and workshop layout.
