SF-5030E Short-cavity double-circulation heat shrink packaging machine

Key Features

1. Short-Cavity Dual-Circulation Hot Air Lightweight and Energy-Saving Design: The SF-5030E is equipped with dual imported SURFON circulating fans, ensuring bidirectional convection circulation of hot air within the furnace. This results in uniform temperature distribution within the furnace without any hot or cold gaps. The short furnace structure significantly reduces overall energy consumption; a rated power of only 18kW is sufficient to achieve a full and compact heat shrinking effect, leading to lower long-term electricity costs compared to long tunnel models. The standard internal cavity dimensions are 1000×500×300mm, allowing for a maximum single-pass volume of goods up to 700×400×200mm. The conveying speed is infinitely adjustable from 0–15m/min, and the temperature control range is 0–300℃. It can accommodate thin PE film, PVC film, and environmentally friendly POF film, making it suitable for small-batch and medium-capacity production lines. Weighing only 309kg, the separate floor-standing support with omnidirectional casters allows for easy relocation and leveling by a single person, making it flexible for placement in small to medium-sized workshops with limited space.

2. A rechargeable solid steel bar conveyor system, suitable for small workpieces without jamming: The conveyor uses a solid steel bar chain structure, with the outer layer of the steel bars covered by a thickened imported high-temperature resistant silicone sleeve, making it wear-resistant and heat-resistant, and preventing scratches on the printed film and smooth product surfaces. For small parts, mini cartons, and other easily dropped materials, an upgraded densely arranged steel roller configuration can be used to reduce roller gaps and eliminate jamming and dropping problems, accommodating both large cartons and small accessories. The entire machine's workbench has a uniform industry standard height of 820±50mm, allowing direct connection to semi-automatic cuff sealing machines and fully automatic side sealing machines without the need for additional elevation modifications to the production line. The loading and unloading height is tailored to manual operation habits.

3. Complete set of international electrical components, stepless speed regulation and precise temperature control: The core electrical components of the entire machine are all from internationally renowned brands: Schneider Electric frequency converters, circuit breakers, and power supply components from France provide stepless speed regulation and circuit safety protection; Autonics high-precision temperature controllers from South Korea monitor the furnace temperature in real time; and GPG geared motors and SURFON circulating fans from Taiwan ensure continuous and stable operation. The entire electrical control system is highly responsive, with independent adjustment of conveyor speed and furnace temperature. Different film thicknesses do not require repeated shutdowns for debugging; one-click matching of adaptation parameters ensures stable temperature during long-term mass production, resulting in a lower defect rate. The equipment supports 220V single-phase and 380V three-phase 50/60Hz universal power supply, allowing direct production in factories both domestically and internationally.

4. Integrated enclosed insulated furnace body, safe and easy to maintain: The entire machine adopts a fully enclosed sheet metal insulated furnace cavity with thickened internal insulation cotton to lock in heat and reduce hot air leakage loss; ventilation windows are reserved on both sides of the furnace body, balancing insulation and equipment heat dissipation, preventing the machine body from overheating and aging. The electrical control panel is centrally located at the front, with emergency stop, temperature control, and speed adjustment buttons conveniently arranged, allowing operators to adjust parameters without having to walk around the machine. The equipment features multiple safety interlocks for motor overload, over-temperature, and emergency stop, automatically shutting down in abnormal conditions to avoid the risks of burns from high temperatures and electrical malfunctions. The modular assembly structure of the entire machine makes disassembly and assembly of the fan, heating element, and conveyor components simple, minimizing daily cleaning and parts replacement time and reducing production line downtime.

5. Multi-film material compatibility + comprehensive after-sales support: The equipment is compatible with PE, PVC, and POF, three mainstream heat-shrinkable films on the market, providing a wider range of consumable options for food packaging and industrial packaging scenarios. Film materials can be switched without changing the internal structure. The manufacturer provides a one-year warranty on the entire machine, free replacement of non-human-caused damage parts (excluding easily damaged parts), and lifetime online technical consultation and troubleshooting guidance services. Internal roller spacing and power configuration can be adjusted according to customer product size and production line conditions, supporting simple non-standard modification needs.

Applications: The SF-5030E lightweight hot air shrink tunnel is a mid-range, economical heat shrink equipment. It needs to be paired with various sealing and cutting main units to form a complete packaging production line, primarily for heat shrinking small to medium-sized, neat single items and multi-item bundles. It is widely applicable to bottled beverages, dairy products, snacks, boxed daily chemicals, small medicine boxes, 3C digital accessories, small hardware parts, decorative panels, small furniture parts, and small automotive parts. It can accommodate both palletized and palletless packaging modes, allowing for individual wrapping to enhance product display quality, as well as bundled packaging of multiple items to prevent scattering during warehousing and transportation. Its short-cavity, lightweight design is particularly suitable for small to medium-sized processing plants, e-commerce packaging workshops, offline gift packaging stores, and small building material processing workshops. It provides stable output for medium-capacity production, with low procurement and operating costs. The film provides all-around dust and moisture protection, as well as scratch and impact resistance, catering to both domestic mass production and export-oriented small-to-medium-sized production line needs.
