The core technology of TPU heat sealing machine in hand massage devices

1. The core technology of TPU heat sealing machine in hand massager

Precision hot pressing molding high frequency patented technology‌
The TPU heat sealing machine heating plate and temperature control chip achieve precise temperature control of ±0.5°C, ensuring that there is no risk of air leakage in the airbag after heat sealing. For example, the Philips 3101A hand massager adopts this technology for its TPU air bag. The heat sealing time is controlled at 5-15 seconds, and the production efficiency is 80% higher than the traditional glue process.

Multi-layer TPU composite process‌
Some high-end brands such as Xilakan use a 5-air bag and 8-zone design to achieve lamination and bonding of the TPU film and lining through a heat sealing machine. The peel strength exceeds 8N/mm and can withstand 100,000 bending tests. Philips' three-zone independent air control system (palm, fingers, wrist) uses a heat sealing machine to complete precision welding with 0.8Hz frequency pressure to ensure the airtightness of the 42°C hot compress function.

Environmental protection and durability optimization‌
The TPU heat sealing process does not require the use of solvents, fully complies with FDA certification, and avoids the VOCs pollution problem of traditional glue processes. At the same time, the heat-sealed parts can still maintain stable performance in extreme environments ranging from -40°C to 130°C, and are suitable for the hot compress function of the massager (such as Xilakan's two-level temperature control) and various storage conditions.

2. Technical characteristics of typical brands

Philips‌: Using three-zone independent air-controlled welding technology and medical-grade air-tight design, it is suitable for deep relaxation and hot compress physiotherapy scenarios. Its airbags have been flexed and tested for 100,000 times to ensure long-term durability.

Mofei‌: It features a glove-style finger-fitting design. The heat-sealing process ensures that the airbags perfectly match the fingers. It also supports fast charging function and is suitable for fragmented relaxation needs in office or home scenes.

Xilaikang‌: Through multi-air bag zoned heat sealing technology, combined with an intelligent temperature control system, it provides precise acupoint stimulation and is suitable for daily health care.

3. Technological breakthroughs and industry trends

The TPU heat sealing machine achieves efficient production of "hour-level curing", shortening the production time of a single piece to less than 15 seconds, and improving the efficiency of the traditional water-based adhesive process by 90%. In addition, thermal sealing technology can handle complex structures, such as the progressive shrinkage design of Philips finger straps to meet the needs of 3D kneading functions. In the future, with the advancement of intelligent temperature control and automation technology, TPU heat sealing technology will be further popularized in the field of hand massagers, promoting the development of products in a more efficient and environmentally friendly direction.
