Pneumatic Cylindrical Battery Sealing Machine for Laboratory Cell Research

Product Overview

This pneumatic cylindrical battery sealing machine is designed for laboratory preparation of cylindrical batteries and cylindrical capacitors. It provides controlled, repeatable sealing through a two-stage sealing process, helping researchers produce secure sample cells with accurate forming and dependable closure quality. The fully pneumatic design operates without electrical power, making the unit straightforward to use in laboratory environments where simple control, compact equipment, and compatible gas handling are important.

The equipment is suitable for battery material development, cylindrical cell assembly, capacitor research, and small-batch pilot production. It is supplied with an 18650 cylindrical battery sealing die set and can be configured with additional tooling for other cylindrical formats. A robust steel structure, adjustable sealing pressure, dedicated exhaust connection, and anti-short-circuit protection support safe and consistent operation during demanding research workflows.

Key Features

• Fully Pneumatic Operation: The unit uses pneumatic actuation and does not require electrical power. This reduces operational complexity and provides convenient manual control for laboratory technicians.

• Two-Stage Sealing Process: Two sealing stations complete the closure in separate operations, improving sealing formation and helping produce a more secure, uniform cylindrical battery package.

• Precision Die Design: Carefully engineered tooling supports accurate sealing geometry and reliable forming. The standard 18650 die set is suitable for common cylindrical battery research and sample preparation requirements.

• Adjustable Sealing Pressure: A regulating valve allows the operator to control sealing pressure according to the material, cell construction, and process requirements. The recommended operating pressure is 0.4 MPa.

• Flexible Gas Supply: The system can use argon or nitrogen from a gas cylinder, or compressed air. Inert gas operation is suitable for moisture- or oxygen-sensitive battery research, while compressed air provides a practical option outside controlled glovebox environments.

• External Exhaust Connection: A dedicated exhaust port can be connected externally through components such as KF40 fittings. This design helps prevent exhaust gas from disrupting the atmosphere inside a glovebox.

• Low Gas Consumption: Each sealing operation consumes approximately 1 L of gas, supporting economical operation during repeated laboratory sample production and small-batch trials.

• Rigid Steel Construction: The solid steel frame improves structural stability during sealing and supports dependable operation over extended laboratory use. The construction is designed for safe, stable forming under controlled pneumatic pressure.

• Compact and Serviceable Design: With a small installation footprint and straightforward operating arrangement, the equipment is easy to position in battery laboratories. Its simple structure also supports convenient routine maintenance.

• Anti-Short-Circuit Protection: The sealing mechanism incorporates a function designed to help prevent battery short circuits during the sealing process, adding an important safety consideration for cylindrical cell assembly.

Applications

Technical Specifications

The pneumatic configuration is particularly suitable for laboratories that need a controlled sealing process without adding electrical equipment to the workstation. Operators can regulate the pressure through the valve and use the recommended 0.4 MPa setting as a practical starting point for standard cylindrical cell sealing. The available pressure range of 0.4 MPa to 0.5 MPa provides adjustment flexibility for process development and tooling requirements.

The standard 18650 tooling addresses one of the most widely used cylindrical battery formats in laboratory research. For programs involving different cell sizes, optional dies can be selected or added for 21, 26, and 32 series cylindrical formats. This tooling flexibility allows one sealing platform to support multiple research projects rather than limiting the laboratory to a single cell geometry.

Gas management is another important consideration for battery and capacitor development. Argon and nitrogen gas cylinders can be used where inert processing is required. Compressed air is also supported for suitable non-glovebox applications, although it is not recommended inside a glovebox. The dedicated exhaust port can be routed externally through KF40 or similar components, helping protect the controlled atmosphere and reduce the risk of exhaust accumulation within the enclosure.

The two-stage sealing arrangement improves control over the forming sequence. Instead of relying on a single closure action, the process uses two sealing operations to improve the final sealing effect. Combined with precision die design and a 30 mm sealing stroke, this arrangement supports accurate forming and a secure cylindrical package for subsequent battery or capacitor testing.

The compact dimensions of 360 mm in length, 220 mm in width, and 490 mm in height make the equipment suitable for laboratory benches, pilot workstations, and specialized assembly areas. Its approximately 30 kg structure provides a stable base while remaining practical to position during laboratory layout changes. The steel construction is intended to withstand regular use and maintain stability during pneumatic forming operations.
