FAQ

Q1: How does the equipment prevent film wrinkles or deformation during drying?

A: The PLC control system precisely manages the step-by-step temperature increase of each heating zone. Combined with variable frequency speed regulation and tension control, the film can pass through the drying process smoothly without wrinkles or deformation.

Q2: What cleanliness level can the oven interior achieve?

A: The equipment adopts a fully welded stainless steel internal structure. High-efficiency air filters are installed in the air circulation system. According to configuration requirements, the cleanliness level can reach up to Class 100 clean environment standards.

Q3: Can the oven process coatings containing volatile organic compounds (VOCs)?

A: Yes. The equipment can be equipped with explosion-proof heating elements, powerful exhaust systems, and reserved exhaust gas recovery interfaces to ensure safe and environmentally friendly operation.

Q4: What maximum film width can the oven handle for continuous drying?

A: The equipment is a customized product. The effective conveyor width is typically between 300 mm and 2000 mm, and can be designed according to the customer's production line requirements.

Q5: What maintenance is required during daily operation?

A: Regular maintenance includes:

Inspecting and cleaning air filters

Removing residues from the conveyor belt

Checking heating element conditions

Applying high-temperature lubricant to transmission chains

These measures help maintain stable equipment performance and extend service life.
