Comparison between ultrasonic cutting knives and traditional cutting knives

 

Ultrasonic cutting:

 

Ultrasonic cutting utilizes the energy of ultrasonic waves to melt the local heating of the material to be cut, thereby achieving the purpose of cutting the material. Due to the ultrasonic vibration of the cutting blade, the frictional resistance is very small, and the cutting material is not easily adhered to the blade. It is particularly suitable for cutting sticky and elastic materials, frozen materials (such as food, rubber, etc.), or objects that are not easily pressurized.

 

 

 

The advantages of ultrasonic cutting:

 

1. High cutting accuracy, material does not deform.

2. The cutting surface has good smoothness and adhesion performance.

3. Easy to apply to automated production.

4. Fast speed, high efficiency, and pollution-free.

5. Low friction improves the production efficiency of cutting operations.

6. Ensure that the incision is neat, smooth, and not deformed, enhancing the appearance and value of the product.

7. The blade body is made of titanium alloy material, which is durable and long-lasting.

8. Continuous cutting can be maintained to further improve production efficiency.

9. It can easily cut materials or products that are difficult to cut using ordinary cutting methods.

10. Easy to operate: Turn on the switch to perform cutting.

11. Small size, installation does not require special equipment.

 

Application of ultrasonic cutting knife:

 

Commonly used for cutting materials that are difficult to cut, such as thermoplastic resin boards, sheets, films, and laminated materials, carbon fiber composites, fabrics, as well as rubber, food, etc.

 

 

 

Traditional cutting:

 

Traditional cutting utilizes cutting tools with sharp edges to concentrate a significant amount of pressure on the cutting edge, pressing against the material being cut. When the pressure exceeds the shear strength of the material being cut, the molecular binding of the material is pulled apart, thus achieving cutting. Due to the material being pulled apart by strong pressure, the cutting edge of the cutting tool must be very sharp, and the material itself must also withstand a considerable amount of pressure. Therefore, the cutting effect is not good for soft and elastic materials, and it is more difficult for viscous materials.

 

Common problems with traditional cutting:

 

1. Need sharp blades and increase the requirement for blades;

2. Cutting cloth cannot seal the edges, as cutting edges can easily cause edge collapse and damage;

3. Sticky objects are not easy to cut and are prone to sticking to the knife, which affects the cutting effect and efficiency;

4. When cutting, pressure needs to be applied to the object, which can easily deform soft or fragile food;

When cutting some items, a large amount of particles and fragments will be generated, increasing waste.
