Pouch Cell Corner Sealing Machine

Product Overview

This corner sealing system is designed for pre-sealing the bottom corner of pouch lithium battery cells. It combines a dedicated corner-form sealing head, adjustable thermal control, pneumatic actuation, and foot-switch initiation in a compact unit. The process positions the cell against a locating baffle so its bottom corner aligns directly with the sealing head before the equipment automatically performs the corner-sealing action.

The equipment is suited to pouch-cell manufacturing workflows where bottom-corner geometry, thermal conditions, and sealing-head alignment require controlled handling. It accommodates compact cell formats within a defined length, width, and thickness envelope, making it relevant to laboratory battery development, process verification, and controlled production operations involving aluminum-plastic film pouch cells.

With sealing-head parallelism specified to ±0.02 mm and temperature deviation specified to ±2.5°C, this unit provides measurable process controls for demanding cell-packaging work. Its 250 mm heating element, R3 mm quarter-circular corner profile, and pneumatic power configuration support a clearly defined operation for repeatable bottom-corner pre-sealing.

Key Features

• Dedicated Bottom-Corner Pre-Sealing: The equipment is specifically configured for the bottom-corner pre-sealing operation of pouch lithium battery cells. The cell side is located against a battery baffle, while the bottom corner is aligned with the dedicated corner-sealing head.

• Automated Foot-Switch Cycle: After the operator places and aligns the cell, a foot switch starts the machine and initiates the automatic corner-sealing action. This sequence keeps the operator focused on accurate cell positioning at the sealing station.

• R3 mm Quarter-Circular Seal Geometry: The sealing head forms an R3 mm 1/4 circular arc corner. This defined head profile supports a consistent corner shape for the specified pouch-cell packaging process.

• Adjustable Thermal Operation: Temperature is adjustable up to 250°C, with a stated deviation of ±2.5°C. The controllable thermal range enables the sealing condition to be set for the applicable aluminum-plastic film and process requirement.

• Precision Head Alignment: Sealing-head parallelism is specified at ±0.02 mm. This alignment parameter is important where uniform contact across the sealing area is required during the bottom-corner operation.

• 250 mm Heating Element: A 250 mm heating element provides the thermal source for the sealing assembly. The defined heater length is a practical procurement parameter when assessing the equipment layout and service requirements.

• Film-Dependent Thickness Groove: The sealing-thickness groove is provided according to the aluminum-plastic film thickness required by the customer. This allows the groove configuration to be matched to the supplied packaging-film requirement rather than using a single unspecified arrangement.

• Defined Pouch-Cell Compatibility: The unit is specified for products within L x W x H dimensions of (10-200) x (5-200) x (2-15). This published envelope gives engineering and procurement teams a direct basis for confirming cell-format suitability before installation.

• Pneumatic Operating Configuration: The equipment requires compressed air of at least 0.6 MPa at 6 L/Min. This stated utility requirement supports installation planning and confirms that the sealing action is designed around a pneumatic power source.

• Compact Equipment Footprint: With dimensions of 413 x 365 x 530 mm (L x W x H) and an approximate weight of 35 Kg, this unit is sized for integration into a dedicated pouch-cell processing station where bench or workstation space must be planned carefully.

Applications

Technical Specifications

The following specifications are derived from the product reference data. Item number RB28 identifies this site-facing equipment configuration. Compatibility should be reviewed against the complete cell dimensions, required aluminum-plastic film thickness, available electrical supply, and compressed-air provision before procurement.

For procurement review, the core process criteria are the supported pouch-cell size range, adjustable temperature condition, sealing-head parallelism, and the required R3 mm quarter-circular corner geometry. Installation planning should also account for the stated 220V/50Hz electrical supply, 1.8KW power requirement, compressed-air demand, and the physical equipment envelope.

The process sequence is deliberately direct: the operator loads the cell, references the cell side against the baffle, aligns the bottom corner to the sealing head, and activates the foot switch. The unit then carries out the automatic corner-sealing movement. This makes the physical handoff points in the operation clear for work-instruction development, station layout, and operator process training.

The specified thickness-groove provision should be addressed during configuration because it is based on the aluminum-plastic film thickness required. Providing the applicable film information enables the groove requirement to be defined against the actual packaging material used in the intended pouch-cell process.

Why Choose This Product

• Defined process geometry: The R3 mm 1/4 circular arc corner, 250 mm heating-element length, and dedicated bottom-corner application provide a clearly specified basis for evaluating suitability for pouch-cell pre-sealing.

• Measurable precision criteria: Adjustable temperature up to 250°C with ±2.5°C deviation and sealing-head parallelism of ±0.02 mm give technical teams concrete parameters for process review and acceptance planning.

• Configuration aligned to packaging material: The sealing-thickness groove is determined according to the required aluminum-plastic film thickness, allowing the equipment configuration to reflect the relevant film requirement.

• Practical installation data: Published electrical, pneumatic, size, and approximate weight information supports realistic planning for a battery laboratory or production work station.

• Straightforward operating sequence: Cell location against the baffle, direct corner alignment, and foot-switch activation establish an understandable workflow before the automated sealing action is performed.
