Customized design of high-frequency molds is crucial for achieving personalized lumbar support functionality. Through the application of high-frequency copper molds, cutting/sealing steel molds, and composite structure molds, complex shaping of lumbar support airbags can be achieved to meet diverse user needs regarding support zones, intensity, and range. Examples include:

- Copper Molds: Suitable for applications such as door panel embossing. Aluminum plates secure copper sheets with strict parallelism tolerance control to ensure mold precision, supporting personalized designs like curved or wave-shaped lumbar support airbags.
- Cutting/Sealing Steel Molds: Enhanced hardness through heat treatment, ideal for high-strength applications such as sunshade cutting/sealing. These molds enable precise edge trimming of lumbar support airbags, preventing burr formation.
- Composite Structure Molds: For instance, two-stage spring molds optimize material compression through a layered pressure mechanism, improving forming accuracy and surface quality of lumbar support airbags.
Process Optimization: Enhancing Sealability and Durability of Lumbar Support Airbags
High-frequency equipment significantly improves the sealability and durability of lumbar support airbags through process optimization, ensuring long-term leak-free and deformation-resistant performance.
- Integrated Welding: Utilizing dual high-frequency cylinders and copper electrode current guidance rods, integrated welding of airbags and tube ports is achieved. This eliminates potential sealing issues associated with traditional two-step processes (single-side welding + tube port welding), increasing welding efficiency by over 50%.
- Multi-Layer Material Welding: High-frequency technology enables the welding of multi-layer thermoplastic materials such as TPU, PVC, and EVA, meeting comprehensive requirements for breathability, elasticity, and durability. For example, welding TPU-nylon composites enhances the airbag’s anti-aging and low-temperature resistance.
- Edge Treatment Technology: Synchronized cutting/sealing mold designs optimize upper and lower mold bodies, reducing burr residue and improving edge smoothness and aesthetics of lumbar support airbags.
