Polypropylene webbing heat sealing machine ultrasonic welding machine

The polypropylene webbing heat sealing machine, also known as an ultrasonic plastic welding machine or nylon hook and loop fastener welding machine, is a device that utilizes ultrasonic vibration energy for plastic welding. This machine welds hook and loop fasteners made of materials such as nylon and polyester without the need for any adhesives, fillers, or solvents, and does not consume a large amount of heat. It offers advantages such as high efficiency, environmental friendliness, and ease of operation.

Working Principle

The polypropylene webbing heat sealing ultrasonic welding machine generates high-frequency electrical energy through an ultrasonic generator. This electrical energy is converted into mechanical vibration energy of ultrasound and transmitted to the welding head. The welding head directly applies this mechanical vibration energy to the surface of the product to be bonded, generating high-frequency vibrations and frictional heat. This causes the plastic to melt and solidify under pressure, forming strong molecular bonds to achieve welding.

Main Features

High Efficiency and Energy Saving: The welding process is fast, typically completed in less than a second, and does not consume a large amount of heat.

Environmentally Friendly and Healthy: No adhesives, fillers, or solvents are required, reducing environmental pollution and health risks for operators.

High Welding Quality: The welding strength is close to that of the raw material, and the welded surface is aesthetically pleasing and durable.

Easy Operation: Highly automated, requiring only simple operations to complete the welding process.

Wide Range of Applications: Suitable not only for welding hook and loop fasteners made of materials like nylon and polyester but also for welding other thermoplastic products.
