Types of heat sealing equipment for different membrane materials

In the production of inflatable massagers, high-frequency heat sealing equipment can be used for different film materials, employing the following equipment types and technical solutions:

I. PVC Film Material Heat Sealing Equipment

Equipment Types: Puxiong High-Frequency Synchronous Welding Machine, Single-Head Push-Panel High-Frequency Machine.

Applicable Scenarios: Welding of PVC air bags (such as leg and waist massage air bags).

Technical Parameters:

Frequency: 27.12MHz or 40.68MHz (International Industrial Band Standard).

Power: 5-8KW (adjustable according to mold size and PVC thickness).

Welding Strength: Peel strength ≥15N/15mm, weld width ≥8mm.

Core Advantages:
High-Efficiency Welding: High-frequency vibration polarizes PVC molecules, generating heat through friction. Welding is completed within 0-10 seconds, supporting alternating operation of dual workstations, with a daily output of thousands of pieces.

Precise Control: The PLC touchscreen control system, combined with a time-based system, maximizes output and welds products in the shortest time, increasing production volume.

Safety Protection:
* Spark Protection: The NL5557 spark protection system automatically cuts off the high-frequency circuit to prevent mold burn-out.

Current Limiting Protection: Cuts off the high-frequency output when the output force is excessively high to protect the electron tube.

Typical Cases:
* Medical Leg Cover Airbag: A multi-cavity airbag structure is formed through high-frequency welding, achieving foot acupoint massage and blood circulation promotion functions.
* Car Seat Massage Module: Utilizes a dual-head hydraulic high-frequency machine to simultaneously complete the welding and cutting of TPU airbags and leather fabric, withstanding extreme temperature environments from -30℃ to 80℃.

II. TPU Membrane Heat Sealing Equipment
* Equipment Type: Puxiong High-Frequency Membrane Structure Welding Machine, Dual-Head Hydraulic High-Frequency Machine.
* Applicable Scenarios: TPU airbag welding (such as massage chair back airbags), soft line indentation punching forming.
* Technical Parameters:
* Frequency: 13.56MHz or 27.12MHz (optional).
* Power: 8-25KW (Supports large-size membrane welding).

Welding Speed: 5-10 meters/minute (servo drive system control).

Core Advantages:

Compatibility: Supports processing TPU hybrid materials containing more than 10% PVC, adaptable to different hardness requirements.

Intelligent Features:
* Laser Positioning System: Precisely positions the welding location, reducing errors.
* European-style High-Frequency Oscillating Chamber: Stable output, uniform welding without knife marks.

Environmentally Friendly: ISO9001 and CE certified, meets medical-grade environmental standards (e.g., APET film folding).

Typical Cases:
* Air Wave Pressure Massager: High-frequency welding of TPU pressure bands forms evenly distributed air chambers, ensuring precise transmission of massage pressure.
* Outdoor Inflatable Massage Mat: Employs an anti-interference high-frequency machine to weld TPU fabric and a waterproof coating, resistant to UV rays and humid environments.

III. Special Membrane Heat Sealing Equipment

Equipment Type: Puxiong Customized High-Frequency Machine (e.g., adjustable material trough span model).

Applicable Scenarios: Welding of polymer materials such as canvas and EVA (e.g., outer protective cover for massagers).

Technical Parameters:

Frequency: 27.12MHz (standard configuration).

Power: 3.5-5KW (lightweight design).

Mold Size: Customizable span (e.g., 750mm and above).

Core Advantages:

Flexibility: Adjustable depth and width of the material feeding slot, supporting large-area continuous splicing (e.g., full-coverage airbags for massagers).

Multifunctionality:

Simultaneous Welding: Welding and cutting are completed in one step, reducing processes.

Embossing Texture: Embossing textured patterns on the airbag surface enhances the massage feel.

Typical Cases:
Car Inflatable Massage Seat: Achieving a balance between lightweight and durability through high-frequency welding of the EVA cushioning layer and leather fabric.

Travel Inflatable Massage Pillow: Using a small high-frequency machine to weld TPU film, reducing volume by 50% after folding for easy portability.
