The application of high-frequency heat sealing machines in outdoor inflatable beds

Specific Applications of High-Frequency (HF) Welding Machines in Outdoor Airbed Production

Air Chamber Sealing Welding
Airbeds form sealed independent air chambers through thermal welding along the edges. HF welding machines enable precise control of weld widths between 0.5-2 mm, ensuring leak-free chamber integrity.
Case Study: A brand uses a 75KW HF welding machine to weld 0.8mm thick PVC-coated fabric, reducing per-unit production time to 2 minutes.

Complex Shape Processing
Equipped with dual-sliding tables or rotary multi-station systems, HF machines simultaneously weld complex air column structures (e.g., strip-shaped, cylindrical, honeycomb) to meet ergonomic design requirements.
Technical Parameters: Adjustable welding pressure (0.1-0.5 MPa), maximum working area of 2000×1800 mm, suitable for double-layer airbed production.

Multi-Layer Material Lamination
By adjusting power and time parameters, HF welding bonds multi-layer materials such as PVC-coated fabric, TPU films, and flocking layers, enhancing product comfort and durability.
Advantages: Weld strength ≥85% of base material, peel strength ≥15N/15mm, passes -30°C low-temperature crack resistance tests.

Technical Advantages of HF Welding Machines
Intelligent Control System
PLC-based human-machine interface stores 10+ welding programs, pre-setting power, time, and pressure parameters for rapid mold changes across product specifications.
Case Study: A manufacturer reduced product changeover time from 30 to 5 minutes using smart HF machines, increasing overall equipment utilization by 40%.

Safety Protection Mechanisms
Integrated spark protection systems (e.g., NL-5557 electronic thyratron) monitor current anomalies and automatically cut off high-frequency output to prevent mold damage.
Safety Design: EMI suppression devices reduce high-frequency interference below international standards, ensuring operator safety.

Modular Design
Customizable sliding table spans and material trough depths, compatible with automated robotic arms for seamless production line integration.
Efficiency Gain: Dual-head four-station models achieve 4,500 cycles/8 hours, tripling the output of single-head machines.
