Core Analysis of the Fully Automatic Rail-mounted ETFE Membrane Material Heat Sealing Machine

1. Equipment definition and functional positioning
The fully automatic track-type ETFE film heat sealing machine is a high-precision welding equipment designed for ethylene-tetrafluoroethylene copolymer (ETFE) film materials. Through high-frequency electromagnetic field or hot air heating technology, the film material is molten and then pressure is applied to complete the bonding. Its core functions include:

Automatic welding: The track-type walking mechanism realizes continuous welding, reduces manual intervention, and improves efficiency.
Precise control: The temperature, pressure, and speed are adjustable to adapt to ETFE film materials of different thicknesses (0.1-5mm) and characteristics.
Multi-scenario adaptation: supports complex curved surface welding needs such as building curtain walls, inflatable membrane structures, and stadium domes.
2. Application scenarios and industry cases
Building curtain wall field
Case: Beijing Daxing International Airport ETFE skylight, using a track-type heat sealing machine to achieve seamless welding of 200,000 square meters of film materials, with a light transmittance of 95%.
Technical requirements: welding strength ≥ 80% of the parent material, air tightness ≤ 0.5L/(m²·h).
Stadium dome
Case: Qatar World Cup Lusail Stadium, 120,000 square meters of ETFE membrane material welding was completed through high-frequency heat sealing machine, and the wind pressure resistance reached 12kPa.
Innovation: The use of dual-track synchronous welding technology reduces the number of joints by 30%.
Inflatable membrane structure
Case: Shanghai Disney "Bubble House" project uses a continuous hot press to achieve PE/ETFE composite membrane material welding, and the air tightness is improved by 50%.

3. Technology development trend
Modular design: supports rapid replacement of welding heads to meet the welding needs of multiple materials such as PVC and PTFE.

Conclusion
The fully automatic track-type ETFE membrane material heat sealing machine is the core equipment of modern membrane structure engineering, and its technological iteration is developing in the direction of efficiency, precision and intelligence. When purchasing, it is necessary to combine the project scale, budget and long-term maintenance cost for comprehensive evaluation, and give priority to equipment with closed-loop control and high degree of automation to cope with the increasingly complex membrane material welding needs.
