Outstanding Elasticity and Abrasion Resistance:
TPU material exhibits excellent elasticity and flexibility, maintaining stable performance across varying temperatures. This makes it ideal for manufacturing lumbar support airbags that require frequent inflation and deflation.
High Wear Resistance and Toughness:
TPU material resists daily wear and deformation, ensuring long-term stability of the airbag.
Welding Machine for TPU Pneumatic Lumbar Supports
For welding TPU pneumatic lumbar supports, high-frequency thermal welding machines are typically used. These machines generate heat through high-frequency electric fields, causing molecular movement within the TPU material to melt and bond layers together. When selecting a high-frequency welder, production capacity must be considered. For example, the double-sliding table push-plate high-frequency welding machine is favored by airbag manufacturers due to its dual workstations, automated welding process, and high efficiency.
Processing Techniques for TPU Pneumatic Lumbar Supports
The manufacturing process for TPU pneumatic lumbar supports includes the following steps:
Material Preparation:
Select TPU material meeting specifications, then cut and pretreat it according to product design.
High-Frequency Welding:
Use a high-frequency welding machine to bond TPU layers into the airbag structure. Parameters such as temperature, pressure, and welding time must be tightly controlled to ensure weld quality.
Valve Welding:
Attach the inflation valve using a high-frequency tube welding machine to guarantee airtightness and connection stability. This method effectively prevents air leakage.
Assembly and Testing:
Assemble the welded airbag with other components (e.g., valves, control mechanisms) and conduct quality tests. Tests include airbag sealing performance, inflation speed, and support effectiveness.
Packaging and Shipping:
Certified products are packaged and prepared for delivery.
Key Factors for Performance and Quality
The material selection, welding equipment, and processing techniques are critical to ensuring the performance and reliability of TPU pneumatic lumbar supports. By choosing appropriate materials, advanced machinery, and optimized processes, manufacturers can produce high-quality, durable TPU lumbar support products.
