The advantages of high-frequency welding in TPU flexible connections

1. Efficient and Precise Welding Control

HFW directly applies a high-frequency electromagnetic field to TPU molecules, causing them to reach a molten state within milliseconds. This process significantly outpaces traditional methods like heat pressing or adhesive bonding.
Example: In surgical robot TPU protective cover production, HFW achieves single-point welding times as short as X seconds, with weld strength exceeding 80% of the base material's strength, drastically improving production efficiency.


2. Seamless Welding and Sealing Assurance

Through molecular friction-induced heating, HFW enables molecular-level fusion of TPU materials in their molten state, forming seamless joints. This is critical in medical applications.
Example: For TPU IV fluid bags, HFW ensures helium leak rates below X cc/min, complying with ISO 11607 medical packaging standards for airtightness.


3. Broad Material Compatibility

HFW accommodates TPU materials of varying thicknesses and imposes no restrictions on color or transparency.
Example: In automotive electronics, HFW simultaneously bonds black conductive TPU with transparent non-conductive TPU, meeting requirements for EMI shielding and visual inspection.


4. Environmental and Cost Benefits

  • Zero VOC emissions: No adhesives or solvents required, aligning with RoHS and REACH regulations.
  • Energy efficiency: Consumes 30-50% less energy than laser welding, reducing per-unit costs in mass production.
