Ultrasound Knife for Rubber

Product Description:

The ultrasound knife for rubber is an industrial cutting system specifically designed for rubber, silicone, and elastomeric plastics. Unlike traditional cutting methods that rely on forceful mechanical compression and shearing, this tool utilizes high-frequency ultrasonic vibration energy for the cutting process. Traditional blades cut by forcefully pressing into and tearing the material-often causing soft rubber to deform, stick to the blade, or develop rough edges-whereas ultrasonic cutting operates in the exact opposite manner. An ultrasonic generator converts mains electricity into high-frequency, high-voltage power (20 kHz or 40 kHz), and a piezoelectric transducer transforms this electrical energy into high-frequency mechanical vibrations at the micron scale. A booster amplifies the vibration amplitude and stably transmits the energy to the cutting tip; the titanium alloy tip vibrates at high frequency against the rubber surface, causing localized, instantaneous softening and molecular chain separation, allowing for cutting with minimal pressure. Simultaneously, the cut edge undergoes micro-fusion sealing, preventing issues such as stringing, edge chipping, or material adhesion.

Application of Ultrasound Knife for Rubber:

Automotive: Cutting of tire treads, rubber weatherstrips, and silicone shock-absorbing components
Electronics: Thermal conductive silicone pads, waterproof sealing rings, and conductive adhesive sheets
Rubber & Plastics: Slitting of rubber compounds and sheets; cutting of rubber hoses
Home Appliances / Medical: Medical-grade silicone accessories, silicone keypads, and sealing rings

FAQ：

What's the maximum cutting thickness of rubber?

It depends on the ultrasonic frequency and power configuration of the ultrasound knife for rubber:
20kHz high-power system: Suitable for thick rubber materials, max cutting thickness reaches 10–20 mm, ideal for thick rubber strips, tire rubber and dense hard rubber.

40kHz high-precision system: Designed for thin delicate silicone sheets and soft gaskets, applicable thickness 0.1–8 mm.

To guarantee perfect cutting effect without melting deformation, we will match the most suitable frequency and cutter head after you provide your rubber samples and actual thickness data.

Can I choose different blade widths?

Yes, we offer multiple standard blade widths for different production demands. Narrow sharp blades are for trimming small rubber gaskets and tiny precision parts; wide flat blades are perfect for slitting large rubber sheets and long rubber strips. All cutter heads are made of wear-resistant titanium alloy with long service life. Besides standard sizes, customized blade width and shape are fully supported according to your workpiece specifications.

Do your ultrasound knife for rubber have CE, RoHS, FCC certificates?

Yes, all our complete ultrasound knife for rubber has passed CE, RoHS and FCC certifications. It fully complies with electrical safety standards for EU, US and most global markets. We can provide full certificate documents for your customs clearance and product inspection upon request.
