Glove Box Compatible Automatic Cylindrical Battery Sealing Machine

Product Overview

This automatic cylindrical battery sealing machine is designed for automated sealing and material transfer of cylindrical cells. Its split configuration allows the sealing unit to operate inside a glove box, supporting controlled-atmosphere battery assembly and reducing manual intervention during critical sealing operations. The system performs first, second, and third-stage squat sealing to produce smooth sealing edges, reliable airtightness, accurate dimensions, and consistent forming quality.

The equipment is suited to cylindrical battery research, pilot-scale cell fabrication, and advanced materials laboratories working with formats such as 18650 and 21700 cells. With interchangeable sealing molds, the unit can be adapted to additional cylindrical battery specifications. Automated loading and unloading, PLC touchscreen control, compact construction, and straightforward parameter adjustment help improve workflow efficiency while maintaining repeatable production results.

A rigid steel structure, precision mold design, and stable pneumatic operation support dependable performance under demanding laboratory and production conditions. The sealing system is engineered for long service life, with a mold lifespan exceeding 3 million cycles. Its compact footprint, accessible controls, and simplified maintenance make it practical for frequent operation in research and manufacturing environments.

Key Features

• Glove Box Compatible Split Design: The split structure allows the sealing section to be installed and operated inside a glove box, supporting cylindrical cell assembly under controlled environmental conditions.

• Automated Loading and Unloading: Automatic feeding and discharge reduce manual handling, improve process continuity, and support more consistent cell-to-cell production.

• Three-Stage Squat Sealing: First, second, and third-stage sealing operations form the cylindrical cell progressively, helping produce smooth edges, reliable airtightness, accurate dimensions, and stable sealing quality.

• PLC Touchscreen Operation: The integrated PLC touchscreen interface makes operating parameters easy to set and supports a high level of automation for repeatable production workflows.

• Precision Mold Engineering: Carefully designed sealing molds help control forming geometry and deliver accurate, reliable sealing results across repeated production cycles.

• High Structural Stability: A robust steel frame provides a stable operating foundation, helping maintain equipment safety, forming consistency, and dependable performance during continuous use.

• Interchangeable Battery Molds: The standard configuration includes an 18650-series sealing mold, while optional molds can support other cylindrical cell specifications, including 21700 formats.

• Compact and Serviceable Construction: The unit combines a compact footprint with convenient operation, attractive industrial design, and simplified maintenance access for laboratory and pilot-line environments.

Applications

Technical Specifications

The sealing pressure reaches a maximum of 3000 kg, providing the forming force required for controlled cylindrical cell sealing. A processing accuracy of ±0.1 mm helps maintain dimensional repeatability across production batches. These characteristics are particularly important when sealing quality affects cell integrity, downstream testing, and comparative research results.

The three-stage sealing sequence is designed to progressively shape the sealing edge rather than relying on a single forming action. This operating method supports a smooth finished edge, reliable airtightness, and consistent dimensions. For laboratories developing or comparing cylindrical cells, repeatable sealing geometry can help reduce process-related variation and improve confidence in subsequent electrical and safety evaluations.

The standard 18650-series mold provides a practical starting configuration for common cylindrical cell research. When a different cell format is required, the mold can be replaced with an optional configuration. This approach allows one compact system to support multiple cylindrical battery development programs while preserving the core sealing and control architecture.

With a production capacity of 6 PCS/min, the equipment is appropriate for repeated laboratory batches and pilot-scale work. The automatic loading and unloading functions help maintain a continuous workflow, while PLC touchscreen control allows operators to set process parameters efficiently. The 220 V / 50 Hz power configuration and 0.5 kW rated power support installation in standard laboratory or pilot-line utility environments, subject to site verification.

The compressed air requirement is 0.5 MPa–0.7 MPa. A stable pneumatic supply should be provided to help maintain consistent sealing pressure and repeatable operation. The compact dimensions of L550 × W420 × H800 mm allow the unit to fit into space-constrained research areas, glove box integration layouts, and pilot production workstations. The 150 kg net weight provides a stable equipment base while remaining practical for planned installation and relocation.
