Ultrasonic Round Hole Punching Machine

The ultrasonic circular hole punching and pressing machine is a composite equipment that combines ultrasonic welding and punching functions, suitable for processing circular or shaped components of materials such as plastics and non-woven fabrics. It features high efficiency, environmental friendliness, and high precision. Below is a detailed introduction to this equipment:

I. Equipment Principle

The ultrasonic circular hole punching and pressing machine converts electrical energy into high-frequency vibrations (typically 20-40kHz) through an ultrasonic generator. These vibrations are then transformed into mechanical vibrations via a transducer and transmitted to the welding mold. Under pressure, the mold contacts the material, generating heat through friction to locally melt the material, achieving welding or punching. Its core advantages include:

No-melt welding: Achieves molecular-level fusion through high-frequency vibrations, with welding strength close to that of the original material, avoiding thermal damage.

Cold cutting technology: The punching process occurs at low temperatures, reducing material deformation and maintaining smooth edges.

II. Equipment Functions

Welding function: Suitable for welding circular or shaped components of materials such as plastics and non-woven fabrics, such as towel embossing and electronic component encapsulation.

High welding strength and excellent airtightness, making it ideal for scenarios requiring sealing or high-strength connections.

Punching function: Capable of simultaneously cutting circular or shaped components, such as welding and cutting ear straps for non-woven masks.

Smooth punching edges eliminate the need for secondary processing, enhancing production efficiency.

Composite process: Some equipment supports integrated welding and punching operations, reducing process transition time and lowering costs.

III. Technical Parameters and Performance

Frequency and power: Frequency range: 20-40kHz, with common models operating at 20kHz or 35kHz.

Power range: 900W to 5600W, catering to workpieces of different sizes. For example, the 2600W model uses a coaxial direct-pressure design to improve welding precision, while the 5600W model can handle large products.

Pressure and precision: Wide adjustable pressure range, adaptable to various materials such as microfiber, cotton, and synthetic fibers.

Welding precision reaches the micron level, making it suitable for manufacturing precision components, such as medical device parts and microelectronic components.

Efficiency and automation: Welding speed can reach 40 pieces per minute, far exceeding traditional processes.

Supports PLC control systems and robotic automatic material handling, enabling fully automated production.
