Blister Shell High Frequency Heat Sealing Machine

The blister shell high-frequency heat sealing machine is a specialized device used for sealing PVC double-sided blister cards. Its working principle and characteristics are as follows:

Working Principle

The blister shell high-frequency heat sealing machine typically operates using the principle of high-frequency electromagnetic induction heating. A high-frequency electromagnetic field is generated between the upper and lower electrodes of the device. Under the influence of this electromagnetic field, the internal molecules of the processed plastic undergo polarization and intense movement, thereby generating heat. Under the pressure of the mold, the plastic reaches a molten state, completing the sealing and welding process.

Main Characteristics

Efficiency: The device uses high-frequency electromagnetic induction heating, which heats up quickly, enabling rapid completion of sealing and welding, thereby improving production efficiency.

Precision: Through high-precision digital temperature controllers and mold design, it ensures the accuracy and consistency of the sealing and welding process.

Stability: The device offers stable performance and can operate continuously for extended periods, ensuring smooth production line operation.

Customizability: Some devices support custom processing and can be designed and manufactured according to specific customer requirements.

Environmental Friendliness: The welding process does not require the addition of any chemical solvents or adhesives, meeting environmental requirements.

Scope of Application

The blister shell high-frequency heat sealing machine is widely used in various fields requiring PVC blister packaging, such as stationery supplies, electronic products, toys, gifts, and hardware tools. It can tightly seal PVC blisters with paper cards, achieving effects such as moisture resistance, dust prevention, aesthetics, and enhanced product quality.

Device Parameters

Different models and brands of blister shell high-frequency heat sealing machines may vary in parameters, but they generally include the following aspects:

Output Power: Typically ranges from 5KW to 10KW, depending on the device model and purpose.

Power Supply Voltage: Generally 380V, though some devices support other voltage specifications.

Frequency: Usually high-frequency, such as 27.12MHz or 40.68MHz.

Welding Area: Determined by the device model and mold design, capable of meeting sealing requirements for different sizes and shapes.

Heat Sealing Time: Adjustable as needed, generally ranging from 0 to 10 seconds.
