The sandwich-style blister packaging machine, dual-blister card blister sealer, is an advanced packaging equipment that combines high-frequency heating technology, pressing technology, and automated control systems. It is primarily used for the heat sealing and welding of plastic materials such as PVC, TPU, EVA, PET, etc. Below is a detailed introduction to the dual-blister high-frequency edge welding and trimming sealer:

I. Working Principle

The sandwich-style blister packaging machine, dual-blister card blister sealer, utilizes high-frequency equipment to generate an electromagnetic wave current field instantly through high-voltage rectification and self-excited high-frequency electron tube oscillation. The processed plastic materials, within the electromagnetic wave field, experience internal molecular polarization friction, generating heat. Combined with a certain amount of pressure, this achieves the melting and sealing effect required for the plastic products to be welded.

II. Application Areas

This equipment is widely used in blister card packaging for stationery products, electronic product packaging (such as MP3, MP4, MP5, etc.), toothbrush packaging, dental floss packaging, toy packaging, gift packaging, hardware tool packaging, USB drive packaging, and other similar fields. Additionally, it can be used for PVC soft wire box forming, plastic welding, PVC processing, and other applications.

III. Main Features

High Efficiency and Automation: The equipment is equipped with an advanced control system that can precisely regulate parameters such as heating temperature, time, and pressure, enabling fully automated operation, reducing manual intervention, and improving production efficiency.

High-Quality Sealing: Through the combination of high-frequency heating and mechanical pressure, it forms a strong and aesthetically pleasing sealed edge structure, enhancing the packaging's sealability and durability.

Precision: With precise mold design and control systems, it ensures that the forming and sealing effects of each product meet design requirements.

Environmental Friendliness: No need for chemical adhesives or solvents, reducing environmental pollution.

Adaptability: Suitable for PVC sheets and card attachments of various sizes, shapes, and thicknesses.

IV. Main Parameters

Power: Depending on the model and specifications, the power generally ranges from 5000W to 25000W.

Power Supply Voltage: Typically 380V, supporting three-phase power.

Frequency: The frequency of high-frequency electromagnetic waves is generally around 27.12MHz.

Sealing Speed: Depending on the equipment model and set parameters, it can complete the sealing of multiple products per minute.

Heat Press Time: Adjustable between 3 to 8 seconds, determined by material thickness and sealing requirements.
