HIPOWER has specialized in high-frequency welding equipment R&D and manufacturing for over 27 years, providing customized solutions for customers in more than 60 countries worldwide.
For projection screen film and high-end PVC membrane manufacturers, weld quality directly determines product performance and appearance. Traditional high-frequency welders often cause material warping, discoloration, and uneven seams, which seriously affect the projection effect and service life of finished products.
To solve these industry pain points, Dongguan HIPOWER has launched the HR-15KW-FL high-frequency welding machine, a purpose-built solution optimized for projection screen film and coated fabric welding. In this article, we will introduce its core technical features, complete technical specifications, application scenarios, and customization options to help you choose the right welding equipment for your production line.
The HR-15KW-FL is equipped with a 15KW high-frequency oscillator and a premium 8T85RB electron tube, operating at the global industry-standard 27.12MHz frequency. This configuration ensures consistent and stable power output even during 24/7 continuous production.
For buyers, this means uniform heat distribution across the entire welding seam, eliminating hot spots that cause material discoloration and deformation—critical for high-quality projection screen film production.
The machine adopts a European-standard square high-frequency oscillatory box, which delivers stronger output power and lower energy loss compared to traditional circular oscillators. Its robust structure ensures long-term reliability with minimal maintenance requirements.
This design significantly improves welding strength, making the weld seam nearly as strong as the base material itself, providing excellent waterproofing and tear resistance for all finished products.
A standard high-sensitivity 5557 anti-spark protection system instantly cuts off high-frequency output within milliseconds when abnormal sparking occurs. This effectively protects both the welding mold and internal electronic components from damage.
For manufacturers, this reduces production waste, minimizes equipment downtime, and lowers overall operating costs.
The machine comes with a built-in laser light position guidance system, which projects a clear alignment line onto the worktable. This helps operators accurately position materials before welding, ensuring consistent seam placement every time.
This feature improves welding precision by up to 30% and reduces the learning curve for new operators, making it easy to achieve professional results with minimal training.
We understand that every production line has unique requirements. The HR-15KW-FL supports comprehensive non-standard customization, including custom lower electrode shapes, sizes, and configurations. Multiple electrode types are available to match any special product design. ODM and OEM services are also available for private label manufacturing.
This flexibility allows the machine to adapt to a wide range of products and production processes, maximizing your investment value.
Safety is our top priority. The ground-press platen is positioned behind the welding mold, completely eliminating the risk of hand injuries to operators during operation. An input air-filtering system protects internal electronic parts from dust and contaminants, extending the service life of the equipment.
The worktable is designed for easy material loading and unloading, improving overall operational efficiency and reducing operator fatigue.
The HR-15KW-FL is designed for high-frequency heat sealing of the following materials and end products:
Projection screen films and large-format advertising banners
Outdoor membrane structures and architectural tensile membranes
PVC tarpaulins, truck covers, and agricultural canvas
Tents, awnings, parking canopies, and sunshades
Inflatable boats, flexible tanks, and gas storage bags
Stretched ceiling structures and exhibition displays
All other PVC/TPU-based thermoplastic-coated fabrics
