Polymer Battery Simple Top Sealing Machine

Product Overview

This polymer battery top sealing machine is designed for the sealing stage of polymer battery fabrication. It combines a heated copper sealing head, guided fixture movement, pneumatic compression, and timed operation in one practical workstation. After the sealing head reaches the selected temperature, the operator positions the battery in the fixture, moves it along the guide rail, and activates the foot switch. The upper sealing head then applies pressure for the programmed duration before automatically returning to its raised position.

The equipment is suited to polymer battery development, pouch-cell preparation, laboratory-scale battery assembly, pilot production, and advanced materials research. Its maximum sealing length of 500 mm supports a broad range of battery formats, while the dedicated electrode-tab positioning block helps locate tabs more accurately before sealing. This makes the unit useful wherever repeatable pouch sealing and controlled operator workflow are essential.

A temperature alarm helps prevent operation before the equipment reaches the required setting, reducing the risk of incorrect sealing caused by premature activation. Pneumatic actuation provides a consistent pressing motion, while adjustable sealing time and temperature control support process development across different battery materials and pouch configurations. The copper sealing head edge is 5.5 mm, and the groove dimensions can be customized from customer drawings for application-specific sealing requirements.

Key Features

• Controlled Polymer Battery Sealing: The equipment is purpose-built for the battery sealing process, providing a dedicated workstation for polymer battery pouch and top-sealing operations.

• Maximum 500 mm Sealing Length: The unit accommodates batteries with a maximum sealing length of 500 mm, supporting small laboratory samples as well as larger development formats.

• Adjustable Sealing Time: Sealing time can be set freely from 1 to 99 seconds, allowing users to adapt dwell time to pouch materials, sealing conditions, and process-development requirements.

• High Timing Precision: Time accuracy is specified at ±0.1 seconds, supporting repeatable cycle control and helping operators maintain consistent sealing results across repeated batches.

• Heated Copper Sealing Head: The copper sealing head provides the direct contact interface for the sealing operation. Its 5.5 mm sealing edge is suitable for controlled top-seal formation.

• Temperature Alarm Protection: A temperature alarm helps prevent incorrect operation before the sealing head reaches the set temperature, supporting safer and more consistent process execution.

• Guided Fixture Movement: The battery fixture moves manually on a guide rail to the lower sealing-head position. This arrangement helps the operator bring the workpiece into a defined sealing location.

• Electrode Tab Positioning Block: An integrated positioning block supports more accurate electrode-tab placement before compression, helping reduce alignment variation during assembly.

• Pneumatic Upper-Head Actuation: When the foot switch is pressed, the cylinder drives the upper sealing head downward. Once the programmed sealing time ends, the cylinder automatically raises the head to complete the cycle.

• Application-Specific Groove Design: Groove dimensions can be customized according to customer-provided drawings, allowing the sealing interface to match specific battery designs and tooling requirements.

Applications

Technical Specifications

The maximum sealing length defines the largest stated battery sealing dimension supported by the equipment. Users should confirm the required fixture and groove configuration before ordering when working with a nonstandard pouch geometry or a sealing profile that differs from the standard interface.

Sealing time is adjustable from 1 to 99 seconds, giving process engineers control over the duration of heated compression. The specified time accuracy of ±0.1 seconds supports repeatable cycle timing during procedure development and routine operation. Actual process settings should be established according to the pouch material, battery design, sealing temperature, and validation results for the intended application.

The sealing head temperature range is listed in the reference specification as MAX 2500C, with temperature control accuracy listed as ±20C. These values should be confirmed with the supplier during technical review, particularly where the application requires a specific unit convention or validated thermal tolerance. The temperature alarm is intended to help prevent the operator from starting the sealing sequence before the head reaches the selected operating condition.

The fixture is positioned manually by pushing it along the integrated guide rail toward the lower sealing-head location. This arrangement keeps the operator involved in loading and alignment while providing a defined travel path for the workpiece. The electrode-tab positioning block gives the operator a dedicated reference for more accurate tab placement, which is important when the sealing area must remain clear of the tabs and other internal cell components.

During operation, the operator places the battery on the fixture and moves the fixture to the lower sealing-head position. Pressing the foot switch activates the pneumatic cylinder and lowers the upper head. The timer then controls the sealing interval. When the selected time expires, the upper cylinder rises automatically and the sealing cycle is complete. This sequence reduces the number of manual actions required during each cycle and supports a consistent operating routine.

The equipment requires an AC220V 2.2 KW power supply and compressed air at 0.6MP or above. The 800W heating tube supplies the heating function for the sealing head. A suitable installation should provide the specified electrical service, compressed-air supply, and enough working space for fixture loading, guided movement, and safe operator access. The listed equipment weight is approximately 120KG, so the supporting work surface and handling plan should be considered during installation.

The copper sealing head has a 5.5 mm sealing edge. Groove dimensions are customized according to customer-provided drawings, making the tooling interface adaptable to project-specific requirements. Buyers should provide accurate drawings and dimensional information during the quotation process so the sealing geometry can be reviewed before manufacture or configuration.
