High Frequency Heat Laminating Machine for Flat Panel Protective Cover

Flat protective cover high frequency thermal laminating machine is a kind of key equipment specially used in the production of flat protective cover, which uses the heat generated by high frequency electromagnetic field to achieve the thermal lamination and encapsulation of materials. The following is a detailed analysis of the flat protective cover high-frequency heat sealing machine:

I. Equipment Overview

Flat protective cover high-frequency thermal laminating machine through the role of high-frequency electromagnetic field, so that the surface of plastic, rubber and other materials to rapidly warm up and reach a molten state, and then through the external pressure to achieve the thermal lamination and encapsulation of the material. This kind of equipment can ensure the sealing, abrasion resistance and durability of the products in the production process of flat protective cover, and meet the market demand.

Second, the working principle

High-frequency electromagnetic field generation: the high-frequency generator inside the equipment generates high-frequency electromagnetic field, usually working frequency is 27.12MHz or higher.

Electromagnetic field into thermal energy: high-frequency electromagnetic field acts on the surface of the material, so that the polar molecules inside the material produce high-frequency vibration, which is then converted into thermal energy.

Material melting and thermal bonding: under the action of high-frequency thermal energy, the surface of the material rapidly warms up and reaches a molten state, at which time the two or more pieces of material are tightly fitted by external pressure to achieve thermal bonding and encapsulation.

Third, the main features

High efficiency: high-frequency thermal lamination is fast and can complete the production of a large number of flat-panel protective covers in a short time.

Precision: through precise control of temperature, pressure and time and other parameters, to ensure the stability and consistency of the quality of heat bonding.

Environmental protection: no need to use glue and other adhesives in the process of high frequency heat lamination, reducing the pollution of the environment.

Multi-functionality: suitable for thermal lamination and encapsulation of various materials, such as PVC, TPU, etc.

IV. Technical parameters (example)

Power: According to the different models of equipment, the power range can vary from a few kilowatts to tens of kilowatts. For example, the power of Yongyuan flat plate protective cover high-frequency thermal laminating machine is 8KW.

Operating frequency: usually high-frequency range, such as 27.12MHz.

Heating time: according to the material thickness and process requirements, the heating time can be adjusted, usually a few seconds to tens of seconds.

Pressure: External pressure is provided by pneumatic or hydraulic device to ensure that the material is tightly fitted.

V. Application Fields

Tablet protective cover high-frequency thermal laminating machine is widely used in the production of protective covers for mobile phones, tablet PCs, e-book readers and other electronic products. With the popularity of electronic products and consumer demand for product quality, the market demand for high-frequency heat laminating machine for flat-panel protective cover is also increasing.

Sixth, the use of precautions

Safe operation: before operation, should ensure that the equipment is well grounded, wear good protective gear to avoid electric shock and scalding and other safety accidents.

Parameter setting: according to the production materials and process requirements, reasonable setting of heating time, temperature, pressure and other parameters.

Regular maintenance: regular cleaning, lubrication and inspection of the equipment to ensure the normal operation of the equipment and extend the service life.

To sum up, flat protective cover high-frequency thermal laminating machine is a kind of high efficiency, accurate and environmentally friendly production equipment, which plays an important role in the production of electronic products protective cover.
