Ultrasonic Knife for Rubber Cut

Product Description:

The ultrasonic knife for rubber cut is composed of ultrasonic transducer, ultrasound horn, ultrasonic cutter head and ultrasonic driving power supply. Its working principle is as follows: The ultrasonic generator converts industrial-frequency mains electricity (50/60 Hz) into high-frequency electrical energy at 20 kHz or 40 kHz. This is then transformed by a piezoelectric transducer into microscopic mechanical vibrations of 20,000 to 40,000 times per second at the micron level. The amplitude is amplified by a booster (horn) and transmitted to a titanium alloy cutting blade. The blade rubs against the rubber cutting surface at high frequency, causing localized instant heating that softens and melt-fuses the rubber molecular chains. As a result, the material can be cut with very little pressure. The heat is concentrated only along the cutting seam, so the overall base material does not experience high-temperature aging or deformation.

Features of Ultrasonic Knife for Rubber Cut

1. Features intelligent automatic frequency tracking; automatically matches the resonant frequency upon startup and compensates power for load fluctuations.
2. Equipped with multiple protection functions-including over-voltage, over-current, over-temperature, and no-load protection-ensuring stable operation and a low failure rate.
3. Utilizes a specially designed titanium alloy ultrasonic cutting blade, offering precise frequency and high wear resistance.
4. The blade is wear-resistant, fatigue-resistant, and ensures uniform heat conduction; the cutting head offers a service life far exceeding that of standard steel blades.
5. Supports integration with PLCs, servo modules, robotic arms, and extrusion lines; can be paired with conveyor belts or CNC motion platforms to achieve fully automated, continuous in-line cutting.

FAQ：

What should be paid attention to when using ultrasonic knife for rubber cut?

1. Although the ultrasonic cutting knife with good quality has good protection, due to the high-voltage circuit inside the equipment, the ground power connector should be prepared when using to avoid danger. At the same time, the operator should not disassemble and refit the ultrasonic cutting knife without authorization, which to avoid accidental risk caused by improper operation.

2. When using the ultrasonic cutter, the operator should pay attention not to let the equipment contact with water. When cleaning the ultrasonic cutter, the operator should also pay attention not to let water enter the interior of the cutter, so as to avoid short circuit and accidents.

How is ultrasonic cutting different from traditional rubber cutting?

Traditional cutting uses a sharp blade and high pressure to shear or tear the rubber. This creates friction, generates dust, leaves sticky residue, and often requires lubrication.

Ultrasonic cutting is fundamentally different. It vibrates the blade at 20,000–40,000 times per second. Instead of tearing, it locally melts the rubber at a molecular level. The result: no dust, no sticking, a smooth sealed edge, and no need for lubricants. It's also much gentler, requiring very little downward pressure, so soft or uncured rubber won't deform.

What is the blade life, and how often does it need replacement?

Blade life is not a fixed number - it depends on three main factors:

1.Material abrasiveness:Soft rubber (e.g., silicone) is gentle on blades. Hard or filled rubber (e.g., carbon-black or glass-filled compounds) accelerates wear.

2.Cutting thickness & frequency:Thicker stacks or continuous 24/7 operation will shorten blade life.

3.Maintenance:Keeping the blade clean and operating at the correct amplitude extends life significantly.

Realistic estimates for our ultrasonic knife for rubber cut:

What happens when blade life ends?
The cut edge will gradually become less clean - you may see slight sticking or unevenness. This is your signal to replace or re-sharpen the blade.
