Key Features
1. Exclusive 1000mm ultra-wide cavity with three-fan three-dimensional hot air circulation design: The SF-10040E is a high-end heat shrink tunnel specifically designed for large-sized goods. The furnace cavity has a passage size of 2500×1000×400mm, and few models of the same power on the market have an ultra-wide 1-meter inner cavity, which can accommodate wide sheets, multi-row combined boxes, and small and medium-sized semi-palletized goods at one time. The top of the machine is equipped with three high-power circulating fans from Taiwan SURFON, forming a three-dimensional cross-flow air duct that ensures uniform temperature throughout the furnace without stratification. Large items will not suffer from defects such as film shrinkage and whitening, edge wrinkles, or loose adhesion on the sides and bottom. The machine has a rated power of 18kW, a temperature control range of 0–300℃, and an independently stepless speed regulation of 0–15m/min. It is compatible with various thicknesses of PE heat-shrink film, features an optimized airflow structure to improve heat utilization, and maintains controllable energy consumption during long-term continuous production. The machine weighs 1025kg, with a thickened, one-piece bent sheet metal body, ensuring no significant vibration or deformation during heavy-duty conveying.
2. A heavy-duty, thickened solid steel rod conveyor system supports optional dense rollers suitable for all types of goods: The conveyor structure uses a thickened solid steel rod chain drive, with the steel rods fully covered by imported thickened high-temperature resistant silicone tubing. This provides high temperature resistance, friction resistance, and strong load-bearing capacity, preventing the bending and collapse of wooden flooring, cases of beverages, and heavy hardware sheets, while also preventing scratches on product paint and printed films. Addressing the issue of small parts and mini gift boxes easily falling through the roller gaps, a densely arranged steel roller accessory can be upgraded to reduce the gap between rollers, making it suitable for both large, wide materials and small, scattered products. The workbench adopts the industry-standard height of 820±50mm, allowing direct connection to various large-width fully automatic edge sealing machines and cuff sealing and cutting equipment without requiring modifications to the production line. The machine is equipped with heavy-duty support feet and swivel casters, simplifying relocation and leveling in large factories, and is compatible with automated production lines using forklifts for loading and unloading.
3. A complete set of internationally renowned brand electrical control components ensures precise, stable, and reliable temperature and speed control: All core electrical components are imported from top-tier brands, suitable for global factory production conditions. French Schneider frequency converters, circuit breakers, and thermal overload relays control the conveyor speed, achieving smooth, stepless speed regulation and seamless start-stop. Japanese Omron high-precision temperature controllers monitor the furnace temperature in real time, with extremely low temperature control errors and no temperature drift during long-term mass production. Taiwanese GPG conveyor geared motors and three SURFON high-temperature circulating fans provide continuous and stable power output, while German Siemens switches and intermediate relays ensure circuit safety. The equipment is compatible with AC220V/380V three-phase 50/60Hz global power supply, allowing direct connection to domestic and international factory power grids. An independent external control cabinet centrally displays all operating buttons, with clear zones for emergency stop, temperature, fan speed, and speed adjustment. Operators can complete all parameter adjustments without needing to walk around the machine, making it extremely easy to learn.
4. Fully enclosed, thickened insulated furnace body with multiple safety interlocks extends equipment lifespan: The furnace cavity is filled with high-density, high-temperature resistant insulation cotton, and thickened red heat-insulating curtains are installed at the equipment inlet and outlet to firmly lock in the high temperature inside the furnace, significantly reducing hot air leakage and loss, lowering the surface temperature of the machine casing, and avoiding the risk of burns to operators. Evenly distributed ventilation holes on both sides of the machine body balance the high temperature inside the furnace with external heat dissipation, slowing down the aging of sheet metal and electrical components. The equipment is equipped with triple safety interlock protection: automatic over-temperature alarm, motor overload power-off, and emergency stop. In the event of abnormalities such as dry burning, motor jamming, or human error, the equipment immediately cuts off the heating and power supply, avoiding the safety hazards of short circuits and equipment damage. The entire machine adopts a modular, split-assembly structure; the fan, heating element, and conveyor rollers can all be disassembled individually. Routine cleaning of dust accumulation, replacement of vulnerable parts, and fault diagnosis do not require disassembling the entire machine, significantly reducing production line downtime.
5. Universal PE consumables combined with flexible customization services and comprehensive long-term after-sales support: The equipment is natively compatible with PE heat-shrinkable film. Market consumables have wide procurement channels and low unit prices. After simple electrical control debugging, it can also be used with PVC film. The manufacturer supports customization of internal roller spacing, heating power, and electrical control configuration as needed, and can perform simple non-standard modifications according to the customer's maximum product width and production line speed requirements. The machine comes with a standard one-year warranty. Original parts damaged due to non-human factors are replaced free of charge; customers only bear the shipping costs. After the warranty period, all spare parts are continuously supplied at factory prices. Lifetime online video and remote text technical consultations are provided for rapid troubleshooting. Remote commissioning guidance and on-site installation and commissioning services are also supported for overseas customers.
Applications: The SF-10040E one-meter ultra-wide extended hot air shrink tunnel is a dedicated back-end supporting equipment for large and medium-sized automated production lines. It needs to be used with wide-width fully automatic side-sealing machines and semi-automatic sealing and cutting machines to assemble a complete packaging production line. It is primarily used for heat shrink molding of wide sheets, multi-piece combined boxes, and small to medium-sized semi-palletized large items.
It widely covers large-item packaging scenarios across multiple industries: Food and beverage industry: pallets of mineral water, cases of alcohol, and multi-row gift boxes; Daily chemical industry: large personal care sets and cased cosmetics warehousing packaging; Building materials industry: wood flooring, decorative wall panels, long profiles, and small door and window accessories; Industrial manufacturing sector: complete sets of automotive parts, large hardware components, and electrical equipment housings; Small furniture items, wide-width plastic sheets, and cased chemical raw materials can all be reliably processed; It supports both palletized and palletless packaging modes, producing flat and compact heat-shrinkable finished products whether single wide-width large items are individually wrapped or multiple items are bundled side-by-side. The film completely wraps the goods, providing all-around dustproof, moisture-proof, rustproof, and protection against damage during transportation. The transparent film also enhances the appearance and quality of goods in warehousing and supermarket displays. The 1000mm ultra-wide cavity is particularly suitable for high-capacity production scenarios such as wood flooring processing plants, large beverage bottling workshops, building material profile production lines, large auto parts manufacturing plants, and large e-commerce warehouses. The equipment has CE, SGS, and ISO9001 international certifications and can meet the needs of domestic mass production and export factories in more than 100 countries around the world.
