Laser cutting technology for magnetic shielding materials

The magnetic isolation sheet laser cutting machine uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated area of the material to quickly reach the melting point, causing it to melt and ablate, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving a thermal cutting method that cuts the workpiece.
Magnetic isolation sheet is a flexible material made of absorbing material, which is mainly used to solve the problem that metal generates eddy current due to skin effect, which weakens the radio frequency signal, interferes with the signal strength of the radio frequency card reader, and causes the card reading failure. Magnetic isolation sheet can effectively reduce the interference of clutter on the equipment, and at the same time protect the electromagnetic waves of the equipment from harming the human body.
Magnetic isolation sheets can be divided into two types: hard magnetic sheets and soft magnetic sheets. Hard magnetic sheets are made of ferrite sheets sintered at high temperature and have high magnetic permeability. Soft magnetic sheets are made by adding alloy magnetic powder to plastic or rubber and then processing and forming. The material is soft and very thin. According to different applications, magnetic isolation sheets need to be cut into different shapes and sizes. Since ferrite magnetic isolation sheets are a kind of magnetic sheet material with higher hardness, the incoming material is in block form and needs to be cut after lamination. The material is hard and it is easy to damage the knife using traditional processing methods, and the processing efficiency of the sheet is low. Therefore, the use of laser processing has become a new trend in ferrite processing. Today, the editor introduces a model, a model commonly used for cutting magnetic isolation sheets—laser cutting machine.

The magnetic isolation sheet laser cutting machine uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated area of the material quickly reaches the melting point, melts and ablates it, and blows away the molten material with the help of a high-speed airflow coaxial with the beam, thereby realizing a thermal cutting method of cutting the workpiece.

Advantages of magnetic isolation sheet laser cutting machine:

★ Narrow slit (0.11 mm ~ 0.15 mm), saving materials;

★ Small thermal deformation of the workpiece;

★ Only positioning is required without clamping or marking, and the workpiece has no mechanical stress and surface damage;

★ Can cut brittle materials and extremely soft and hard materials;

★ The incision has good parallelism and clean cutting edges, and can be directly used for welding;

★ High cutting speed (up to 10 m/min or more);

★ Easy to realize CNC or computer control, and can be operated in multiple stations, etc.
