The advantages of Oscillating  knife cutting machine compared to laser cutting machine in felt cutting

定台振刀切割机

1、 Environmental and safety advantages

The vibration knife cutting machine adopts a physical cutting method, which directly contacts the material through high-frequency vibration blades (tens of thousands of times per minute) for cutting, without high temperature participation throughout the process, avoiding smoke, odor or material carbonization problems caused by high temperature in laser cutting machines. For example, when laser cutting felt, high temperatures may cause yellowing or even burning of the edges, affecting aesthetics. In addition, the vibrating knife does not require complex exhaust gas treatment equipment and meets strict environmental requirements, especially suitable for indoor production environments that are sensitive to air quality.

2、 Cutting quality and material integrity

1、Smooth edges without damage
The high-frequency vibration technology of the vibrating knife enables the blade to cut materials with small displacements, resulting in a smooth and burr free cut, especially suitable for materials such as felt that are prone to fiber scattering. In contrast, the thermal effect of laser cutting may cause hardening or deformation of the felt edge, affecting its flexibility and subsequent processing performance.

2、Multi layer cutting capability
The vibrating knife can cut multiple layers of felt sheets (such as car mats or composite felt boards) at once, significantly improving efficiency; However, laser cutting machines are limited by thermal conduction and can usually only operate in a single layer, making it difficult to handle thick materials.

3、No heat affected zone
The cold cutting characteristics of the vibrating knife avoid physical or chemical changes in the material caused by high temperatures, ensuring that the original properties of the felt (such as sound absorption and insulation effects) are not damaged.

3、 Material adaptability and process flexibility

1、Wide compatibility
The vibrating knife can adapt to felt materials of different thicknesses and hardness by replacing the cutting head (such as round knife, oblique cutting knife, milling cutter, etc.). For example, thick felt boards require deep cutting with milling cutters, while thin felt sheets are suitable for fine cutting with round knives. Laser cutting machines have significant limitations on material thickness, and excessively thick felt may not be able to fully penetrate.

2、Breathable material adaptation
The vibrating blade felt belt (cutting machine worktable) has excellent breathable and suction functions, which can stably adsorb felt sheets, prevent displacement during processing, and thus improve accuracy. Laser cutting machines have higher requirements for material fixation, and insufficient vacuum adsorption can easily lead to cutting deviation.

4、 Comparison of Efficiency and Economy

1、Cutting speed advantage
The cutting speed of the vibrating knife can reach 1500mm per second, which is several times that of the laser machine, especially suitable for large-scale production. For example, in the automotive interior industry, vibrating knives can quickly cut complex shaped felt, significantly reducing delivery times.

2、Low energy consumption and maintenance costs
The power consumption of the vibrating knife is only 5-10 degrees per hour, far lower than the 30 degrees of the laser machine; The cost of tool replacement is also lower than the frequent maintenance cost of the laser head. Although the initial investment in equipment is relatively high, the long-term operating cost is more advantageous.

3、Reduce material waste
The high-precision typesetting function of the vibrating knife can maximize the use of felt materials, optimize cutting paths with intelligent software, and reduce waste rates.

5、 Targeted application scenarios

For felt processing that requires high precision, environmental friendliness, and multi-layer cutting (such as customized home soft furnishings and automotive interior parts), vibration knives are a better choice. Laser cutting machines are more suitable for fast sampling of single-layer thin felt or scenarios that do not require fine edge processing, but their environmental limitations and thermal effects still need to be carefully considered.

conclusion

The vibration knife cutting machine, with its environmental friendliness, high precision, material adaptability, and economy, has demonstrated comprehensive advantages in the processing of felt sheets and felt boards, especially suitable for enterprises with high requirements for production efficiency and product quality. With the advancement of intelligent manufacturing technology, the application of vibration knives in the field of felt processing will further expand, promoting the industry’s transformation towards efficiency and green direction. When selecting equipment, enterprises can prioritize vibration knife cutting solutions based on production scale, material characteristics, and environmental requirements.
