What are the advantages of the TPU airbag heat sealing machine for hand massage devices

I. Core Advantages of the TPU Inner Cap Heat Sealing Machine

**Precise Temperature Control and Efficient Molding:** The melting point of TPU hot melt adhesive film typically ranges from 110℃ to 140℃. The heat sealing machine can precisely control the temperature, avoiding damage to the TPU material (such as the airbag components of Philips hand massagers), while achieving rapid hot pressing molding in 5-15 seconds, increasing efficiency by 80% compared to traditional processes.

**High Elasticity and Fatigue Resistance:** TPU materials (such as BASF 1190A) have high elongation (>500%) and abrasion resistance (15% reduction in coefficient of friction). The airbag processed by the heat sealing machine can withstand 100,000 bends without delamination, ensuring the durability of the massager during long-term use.

**Environmentally Friendly and Safe Compliance:** The heat sealing process requires no solvents, complying with environmental standards such as REACH and FDA, avoiding VOC pollution problems associated with traditional adhesives. It is suitable for manufacturing medical-grade hand massage devices (such as the Philips 42°C hot compress model).

**Environmentally Friendly and Safe Compliance:** The heat sealing process requires no solvents, complying with environmental standards such as REACH and FDA, avoiding VOC pollution problems associated with traditional adhesives. II. Technical Adaptability and Application Scenarios

Complex Structure Bonding: The heat sealing machine can handle the precision welding of segmented finger airbags (such as independent airbags for fingers and palms) in Philips massagers, ensuring the realization of the 3D kneading function.

Weather Resistance Guarantee: TPU heat-sealed parts remain stable in environments ranging from -40℃ to 130℃, meeting the requirements of the massager's heat therapy function (42℃) and extreme storage conditions.

III. Breakthrough Compared to Traditional Processes

Comparison Items: TPU Heat Sealing Machine Process Traditional Adhesive Process

Bond Strength: Peel strength > 8N/mm; Susceptible to humidity, uneven strength

Environmental Protection: Solvent-free, FDA certified; Contains VOCs, requires additional treatment

Production Efficiency: Single-piece hot pressing time < 15 seconds; Curing takes several minutes to several hours

Note: TPU airbag components in Philips and other brand hand massagers require seamless sealing via heat sealing to ensure the airtightness and safety of the 42° heat therapy function.
