A brief description of the high-frequency welding characteristics and advantages of anti-static TPU flexible connections

I. Core Features of High-Frequency Welding

1. Molecular-Level Fusion with Superior Sealing Performance
   High-frequency welding uses an electromagnetic field to generate frictional heat at the molecular chains of TPU, achieving molecular-level fusion under pressure to form seamless welds. This method requires no adhesives, and the weld strength approaches that of the base material. The resulting smooth, protrusion-free surface makes it ideal for applications demanding high cleanliness, such as medical and electronics industries.

2. Precise Temperature Control Prevents Thermal Damage
   The heat generated in high-frequency welding is concentrated within the welding zone, with an extremely small heat-affected area. This prevents overall material deformation or performance degradation. By adjusting frequency and power, welding depth can be precisely controlled to accommodate TPU materials of varying thickness and hardness.

3. Compatibility with Transparent and Functional Materials
   High-frequency welding is suitable for transparent TPU materials while maintaining high light transmittance after welding, meeting real-time monitoring requirements. Additionally, the welding process does not disrupt the distribution of anti-static agents, ensuring that the welded soft joints retain both conductivity and transparency.

II. Advantages of High-Frequency Welding for Anti-Static TPU Soft Joints

1. Durable and Stable Anti-Static Performance
   High-frequency welding does not damage the anti-static structure within the TPU. The surface resistance remains stable after welding, effectively preventing electrostatic accumulation and discharge. This is particularly critical in electronics manufacturing and chemical industries, where it mitigates risks of equipment failure or safety hazards caused by static electricity.

2. Excellent Chemical Resistance and Weathering Performance
   TPU inherently resists acids, alkalis, and oils. High-frequency welding further enhances the density of the weld seam, enabling soft joints to function reliably in harsh environments without leakage. Moreover, TPU’s exceptional low-temperature resistance ensures that the welded soft joints remain flexible even under extreme cold conditions.

3. High Production Efficiency and Controllable Costs

• Fast Welding Speed: Short processing time per welding point, combined with automated equipment, enables continuous production and significantly improves efficiency.
• High Yield Rate: The welding process introduces no mechanical stress, minimizing material deformation and risks of weak welds, thereby reducing the defect rate.
• Low Maintenance Costs: High-frequency welding equipment features a simple structure with long-lasting consumable parts, resulting in lower overall maintenance costs compared to other welding methods.

4. Environmentally Friendly and Compliant with Regulations
   High-frequency welding requires no solvents or adhesives, producing zero VOC emissions and complying with environmental regulations. Furthermore, anti-static TPU materials are non-toxic and odorless, meeting safety standards for industries such as food and healthcare.
