Which large-scale heat sealing machines are used in membrane structure buildings

Types of Large High-Frequency (HF) Thermal Fusion Machines for Membrane Structures
In membrane structure construction, the following types of high-frequency thermal fusion machines are widely used, each designed for specific applications:

1. C-Frame HF Membrane Welding Machine

Features:

• Wide Power Range: 8kW–25kW, adaptable to welding tasks of varying scales.
• Robust Structure: C-frame steel construction with rear-mounted grounding for safety.
• Large Workspace: C-shaped material compartment (1150mm width) with roller-assisted feeding for handling wide-span materials.
• High Stability: Powerful output for welding PVC, TPU, mesh-reinforced fabrics, and coated textiles.

Applications:

• Joining PVC biogas digesters and water storage tanks.
• Fabricating awnings, tensile membranes, retractable canopies, outdoor banners, and truck tarps.

2. Track-Guided HF Fusion Machine

Features:

• Customizable Track Length: Supports continuous welding of large membrane sheets.
• High-Efficiency Design: Ideal for industrial-scale production with powerful output.
• Precision Welding: Track-guided movement ensures accurate seam alignment, minimizing manual adjustments.

Applications:

• Seaming membranes for large-scale structures (e.g., sports arenas, parking sheds).
• Mass production of tents and temporary shelters.

3. Roller-Fed Automatic Fusion Machine

Features:

• Automated Feeding: Roller-driven system for continuous material handling.
• Adjustable Speed: Adaptable to materials of varying thicknesses.
• Tension Control: Maintains flat, wrinkle-free welding for uniform results.

Applications:

• Edge sealing for long-strip membrane structures.
• Automated production of advertising banners and tarps.

4. PTFE/ETFE Membrane-Specific Fusion Machine

Features:

• Specialized Design: Optimized for high-performance PTFE and ETFE membranes, including coated variants.
• Precision Temperature Control: Prevents overheating damage to sensitive surfaces.
• Durable Seals: High bond strength for long-term outdoor durability.

Applications:

• Joining ETFE membrane structures (e.g., air-supported domes, daylighting roofs).
• Welding PTFE membranes in tensioned fabric architectures.

5. Rotary Multi-Station HF Fusion Machine

Features:

• Automatic Turntable: Enables multi-station parallel processing for high throughput.
• Robotic Handling: Integrated robotic arms for automatic loading/unloading during welding.
• Precision Indexing: Ensures accurate alignment via precision indexing mechanisms.

Applications:

• Batch welding of standardized components (e.g., connectors, mounts) for membrane structures.
• Mass production of automotive covers and tents.
