1. Working Principle of the Ultrasonic Punching System: "Gentle Cutting" with High-Frequency Vibration
Unlike traditional mechanical punching systems, which rely on immense pressure to "squeeze" materials, the core principle of ultrasonic punching systems is the use of high-frequency mechanical vibrations to achieve precise material separation. Its workflow can be divided into three key steps:
Energy Conversion: The ultrasonic generator in the system converts industrial-frequency electrical energy into high-frequency alternating current (20-40kHz), which is then transmitted to the transducer;
Vibration Generation: The transducer further converts the high-frequency electrical energy into mechanical vibrations of the same frequency (typically with an amplitude of 10-50μm), amplifying the vibration energy through a horn;
Punching Execution: The vibration energy is transmitted to the punching die, which contacts the material in a high-frequency vibration state, instantly inducing localized internal stress fatigue in the material, completing the cut or blanking process with minimal pressure.
This "vibration cutting" mode avoids the extrusion deformation of materials caused by traditional punching and is particularly suitable for flexible or brittle materials such as plastics, rubber, and fabrics.
II. Multi-Industry Applications: From Flexible Materials to Precision Components
Ultrasonic punching systems are highly adaptable and have been widely used in 3C electronics, automotive manufacturing, medical consumables, packaging and printing, and other fields, solving processing challenges that are difficult to overcome with traditional processes:
1. 3C Electronics Industry: Precision Component Processing
Applications: Mobile phone earpiece dust screens, camera module light shields, and flexible printed circuit (FPC) punching.
Technical Advantages: Punching accuracy reaches ±0.02mm, eliminating burrs and deformation, avoiding damage to FPC circuitry caused by traditional punching, and increasing the pass rate to over 99.5%.
2. Medical Consumables Industry: Sterile, Stress-Free Processing
Applications: Punching earloop holes for disposable masks, cutting special shapes for medical dressings (such as Band-Aids), and precision cutting of IV tubing connectors.
Technical Advantages: High-frequency vibration creates a "thermal cutting" effect, resulting in a smooth, sealed cut surface that prevents fiber shedding and meets medical sterility standards.
3. Automotive Manufacturing Industry: Batch Processing of Flexible Materials
Applications: Automotive interior sound insulation, door sealant punching, and lithium battery separator cutting.
Technical Advantages: Supports continuous punching of wide-web materials (maximum processing width up to 2m) at speeds up to 60 punches per second, increasing efficiency by 30% compared to traditional mechanical punching and reducing mold wear by 50%.
