Ultrasonic Rubber Cutting Knife | Precision Rubber Cutter Manufacturer

What Is an Ultrasonic Rubber Cutting Knife?

An ultrasonic rubber cutting knife is a high-frequency cutting device that uses ultrasonic vibration energy to achieve fast, clean, and precise cutting of rubber, silicone, and other elastomeric materials. Unlike traditional mechanical cutting, the ultrasonic cutter converts electrical energy into high-frequency mechanical vibrations, allowing the blade to pass through soft or sticky materials effortlessly, without deformation, sticking, or residue.

This technology is widely used in rubber product manufacturing, tire industry, automotive parts, gasket production, silicone sealing materials, and composite rubber processing.

How Does the Ultrasonic Cutter Work?

The ultrasonic rubber cutting system consists of an ultrasonic generator, transducer, booster, and cutting blade.

When the generator outputs a high-frequency signal (typically 20kHz–40kHz), it drives the transducer to convert electrical energy into mechanical vibration. The blade vibrates tens of thousands of times per second, effectively reducing the friction between the blade and material, ensuring smooth, precise, and burr-free cuts.

Key working principles:

The ultrasonic blade vibrates longitudinally at 20,000–40,000 times per second.

The vibration energy breaks molecular bonds of the material along the cutting line.

Minimal cutting resistance and no deformation of the rubber surface.
