Split Type Top Side Pouch Cell Sealing Machine

Product Overview

This split-type heat sealing system is designed for sealing the top and side edges of lithium-ion pouch cells. It applies heat and controlled pressure to aluminum-plastic packaging film, softening the material toward its fusion state so the layers can be compression-bonded into a clean, consistent seal. The same equipment supports both top sealing and side sealing without changing the sealing head.

The unit is suited to pouch-cell fabrication workflows in lithium battery research, pilot-scale development, and laboratory production. Its separated configuration allows the heat-sealing section to be placed inside a glovebox, supporting processes that require a controlled working environment while keeping the operating controls accessible.

Copper sealing heads, pneumatic actuation, linear-guide alignment, adjustable pressure, and independently adjustable upper and lower temperatures provide the process control needed for repeatable sealing. The compact equipment is built to deliver flat, uniform seal marks and visually neat edge profiles across different pouch-cell sizes.

Key Features

• Split-Type Glovebox Compatibility: The heat-sealing section is separated from the main unit and can be placed inside a glovebox for controlled-environment pouch-cell sealing operations. This configuration helps laboratories integrate the equipment into existing protected-atmosphere workflows.

• Top and Side Sealing Without Tool Changes: The sealing arrangement performs both top-edge and side-edge sealing without replacing the mold or sealing head. This reduces setup work when production steps require different pouch-edge sealing orientations.

• Copper Heat-Sealing Heads: The sealing heads are manufactured from copper to promote effective heat transfer from the resistance heating elements to the packaging film. Efficient thermal conduction reduces energy consumption and supports productive, stable operation.

• Independently Adjustable Head Temperatures: Upper and lower sealing-head temperatures can be set through the temperature-controller panel buttons, while the current temperature value is displayed for process monitoring. Standard upper and lower head settings are both 180℃.

• Adjustable Pneumatic Sealing Pressure: A pressure-regulating valve allows operators to adjust the pressure applied by the upper and lower sealing heads. This enables the equipment to accommodate different process parameter requirements for aluminum-plastic film bonding.

• Pneumatic Motion With Linear Guidance: The upper and lower sealing heads are cylinder-driven and guided by two linear guide sleeves. This arrangement provides flexible vertical motion and accurate guidance, helping maintain the parallelism required after edge sealing.

• Adjustable Sealing Dwell Time: Standard sealing time is 2S-3S, with an adjustable range of 0-99s. The broad dwell-time setting range gives process teams a practical control point when establishing or refining sealing conditions.

• Flexible Cell-Size Adaptation: The equipment can be used with pouch cells of different specifications, with simple adjustment and no need to change the sealing heads. This supports laboratories that work across multiple cell formats or development stages.

• Compact, Clean Sealing Results: The compact structure is intended to produce smooth and uniform seal impressions with a neat finished edge appearance. Consistent head guidance and controlled pressure support a more presentable pouch-cell package finish.

Why Choose This Product

• Process-Focused Mechanical Design: Copper sealing heads, pneumatic drive, and dual linear guide sleeves combine thermal efficiency with accurately guided sealing-head movement. The resulting arrangement is designed around consistent compression alignment and clean pouch-edge finishing.

• Practical Control of Critical Variables: Temperature, pressure, and sealing time are adjustable from the equipment controls and pneumatic regulation system. This gives process teams direct access to the parameters that govern thermal compression sealing conditions.

• Reduced Setup Burden: One sealing-head arrangement handles both top and side sealing, while different pouch-cell specifications can be accommodated without changing the sealing heads. This simplifies routine adjustment across varied laboratory cell formats.

• Built for Controlled-Environment Work: The separated heat-sealing section can operate inside a glovebox, making the equipment a practical choice for lithium-battery workflows that need the sealing process positioned within a protected workspace.

• Efficient and Professional Finish: Copper heat transfer supports energy-efficient operation, while controlled guided motion helps achieve the flat, uniform seal marks and neat edge appearance expected in pouch-cell packaging work.
