FAQ

Q1: How does this tunnel furnace ensure uniform heat shrinking for products of different sizes?

A1: The equipment is equipped with a bidirectional hot air circulation system and adjustable air outlets. Combined with high-precision PID temperature control, it ensures that all sides of the products receive uniform heating, preventing wrinkles or uneven shrinkage.

Q2: Can the conveyor speed and temperature be adjusted together?

A2: Yes. The control panel supports independent adjustment of temperature and conveyor speed. Operators can flexibly match the optimal heating time and conveying speed according to the material type and thickness.

Q3: Can this equipment be used for precise temperature control of biodegradable materials such as PLA?

A3: Yes. The equipment provides temperature control accuracy of ±1°C, strictly meeting the process requirements of biodegradable materials that are highly sensitive to temperature ranges, effectively preventing material failure caused by overheating.

Q4: Does the tunnel furnace consume a lot of electricity? What energy-saving designs are included?

A4: The equipment adopts a thickened insulation layer and internal hot air circulation mechanism to reduce heat loss. After reaching the preset temperature, the heater switches to pulse intermittent heating mode, significantly reducing energy consumption.

Q5: Does the equipment have safety protection if materials become jammed on the production line?

A5: Yes. The equipment is equipped with conveyor overload protection, and prominent emergency stop buttons are installed at both the feeding and discharging ends. In case of abnormal conditions, the conveying and heating systems can be stopped immediately with one button to protect operators and materials.
