Product Parameters

Product Features

High-Precision Temperature Control:

The equipment adopts intelligent microcomputer PID control algorithms. Each temperature zone is independently controlled, and the temperature difference inside the furnace is controlled within ±1.5℃.

High Cleanliness:

Built-in high-efficiency Class 100/Class 1000 air filtration system effectively prevents dust particles from falling onto the uncured film surface.

Tension Control:

Equipped with a micro-tension constant-speed conveying system to prevent film stretching, deformation, or scratching under high-temperature baking conditions.

Energy Saving and Environmental Protection:

The special thermal insulation structure combined with the hot air circulation reuse system reduces overall energy consumption by more than 20%.

FAQ

Q1: How does this tunnel furnace ensure that no bubbles or pinholes appear on the film surface during drying?

A1: The equipment adopts a gradient temperature control design. The film passes through the low-temperature preheating zone, medium-temperature evaporation zone, and high-temperature curing zone sequentially. This allows solvents to evaporate slowly from the inside to the outside, preventing premature surface skin formation and avoiding bubbles.

Q2: Can the equipment adapt to films with different thicknesses and materials?

A2: Yes. The conveyor speed supports stepless variable frequency adjustment, and each temperature zone can be independently adjusted. Users can set customized "speed-temperature" process curves for PET or PVC films with different thicknesses.

Q3: How is the dust prevention problem solved in high-cleanliness film processing?

A3: The interior of the tunnel furnace adopts a full stainless steel mirror-finished panel structure. The air duct outlets are equipped with high-temperature resistant high-efficiency particulate air filters (HEPA), forming a micro-positive pressure laminar flow clean environment to prevent dust contamination.

Q4: What is the energy consumption of this equipment? Does it have energy-saving designs?

A4: The equipment adopts a high-density high-quality rock wool insulation layer, keeping the outer shell temperature close to room temperature. The hot air system is equipped with internal circulating return air function, fully utilizing waste heat and saving approximately 25% electricity compared with traditional ovens.

Q5: Does the equipment have safety alarms and emergency functions?

A5: Yes. The system integrates over-temperature power-off alarms, transmission fault alarms, leakage protection, and emergency stop buttons at the front and rear ends, ensuring safe production operation.
