Shrink Packaging Tunnel Oven

Dingfeng, as a professional manufacturer, has equipped six 1.5-kilowatt stainless steel heaters in its high-quality Shrink Packaging Tunnel Oven. The heaters are equipped with specialized heat dissipation fins. Through our independently developed 8-inch stainless steel volute fan, the heat can be evenly transferred to the product surface. The internal-external curing logic shortens the heating time and extends the constant temperature time, which can prevent surface defects. Existing and new customers can place bulk orders through us.

Furnace cover design

The outer plate of Shrink Packaging Tunnel Oven is made by bending and forming of national standard 1.5mm cold plate. The inner liner is assembled and welded with national standard 1.2mm mirror-finish stainless steel plates. The joint parts are fully welded with all argon arc. The heating system is equipped with 6 stainless steel heating tubes with 1.5KW power each, with heat dissipation spikes. The hot air circulation uses an 8-inch specially made stainless steel shell. The air outlet is equipped with a wind guide plate. The inside of the furnace cover is filled with 120K silica-alumina insulation rock wool. The inner liner has an air insulation layer. The dual-function insulation design effectively reduces the surface temperature of the equipment.

Core advantage

The overall appearance of the Shrink Packaging Tunnel Oven is made of a high-gloss pure white high-temperature baked paint body with black decorations. It can also be customized in color as per requirements. The structure adopts a modular design, capable of supporting 24-hour uninterrupted smooth operation. It is equipped with an RKC digital temperature controller and SSR solid-state relay, along with stainless steel heating tubes and variable frequency motor drives. This enables ±5°C uniform temperature control, long-life heating, and smooth, stepless speed adjustment. It is equipped with a one-button start/stop function and uses a Teflon mesh belt conveyor combined with a deviation prevention device.

Frequently Asked Questions

Q1: How do the heat dissipation fins on the heating tube improve the shrinkage quality?

Answer: The standard tube has a limited surface area, which can lead to hotspots. The heating tube with fins increases the contact area with the circulating air, resulting in more uniform heating.

Q2: Is the 6000N electric lifting system suitable for frequent maintenance?

Answer: Of course. When used in combination with the nickel-plated mechanical safety guard, it has a dual locking system. Even in the event of a power outage, the mechanical guard can prevent the lid from falling and ensure the safety of technicians during cleaning or inspection.

Q3: Can this oven be integrated into an automated conveying line?

Answer: Yes. Equipped with a frequency converter with a digital interface, you can synchronize the speed of the tunnel with the upstream bagging equipment or the downstream labeling equipment. We also provide reserved connection points in the PLC to achieve seamless industrial 4.0 connection.
