The advantages of high-frequency welding in TPU flexible connections

I. Core Advantages of High-Frequency Welding

1. Efficient and Precise Welding Control
   High-frequency welding directly acts on TPU molecules via a high-frequency electromagnetic field, enabling them to reach a molten state within milliseconds. The welding speed far exceeds that of traditional heat pressing or adhesive bonding processes. For example, in the production of surgical robot TPU protective covers, high-frequency welding achieves single-point welding in an extremely short time, with welding strength reaching over 80% of the material's base strength, significantly enhancing production efficiency.

1. Seamless Welding and Airtightness Assurance
   High-frequency welding generates heat through molecular friction, allowing TPU materials to achieve molecular-level fusion in a molten state and form seamless connections. This characteristic is particularly critical in the medical field. For instance, in the welding of TPU infusion bags, the high-frequency process ensures minimal air permeability at the weld seams, complying with the ISO 11607 medical packaging standard.

2. Broad Material Adaptability
   High-frequency welding is suitable for TPU materials of varying thicknesses and imposes no special requirements on color or transparency. For example, in the automotive electronics sector, high-frequency welding can simultaneously handle the composite bonding of black conductive TPU and transparent non-conductive TPU, meeting both electromagnetic shielding and visual inspection needs.

3. Environmental and Cost Benefits
   High-frequency welding requires no adhesives or solvents, resulting in zero VOC emissions and compliance with RoHS and REACH environmental regulations. Additionally, its energy consumption is only 30%-50% of that of laser welding, reducing per-unit welding costs in mass production.
