Product Overview
This laboratory manual cylindrical battery sealing machine is designed for the third sealing operation, also known as bottom or recessed crimping, of cylindrical cells. Its hydraulic drive applies controlled forming pressure through a precision sealing die, producing smooth sealing edges, reliable airtightness, accurate dimensions, and consistent results across repeated laboratory operations.
The equipment is supplied with a die for 18650 cylindrical battery third sealing and can be configured with other cylindrical battery sealing dies when required. Its compact footprint, low manual operating effort, and glovebox-compatible design make it suitable for battery R&D laboratories, pilot-scale cell fabrication, academic research, and advanced materials development.
A rigid high-strength chromium steel structure, environmentally treated surface, precision die construction, and integrated pressure gauge support stable operation under demanding conditions. The hydraulic mechanism is designed for low-vibration sealing and efficient force transmission, helping reduce the risk of liquid leakage and improving process repeatability.
Key Features
-
Purpose-Built Third Sealing: Designed specifically for the third sealing operation of cylindrical batteries, with the standard configuration supporting 18650 cell formats and optional dies available for other cylindrical battery sizes.
-
Controlled Hydraulic Forming: Hydraulic drive provides a maximum pressure of up to 8 tons, enabling firm and stable sealing without vibration during cell forming.
-
Integrated Pressure Monitoring: The built-in pressure gauge allows operators to observe sealing pressure directly and control the forming process with greater accuracy.
-
Smooth and Airtight Sealing: Precision forming helps create even sealing edges, strong airtightness, accurate dimensions, and consistent finished-cell geometry.
-
Low Manual Operating Effort: The specially designed hydraulic structure reduces the force required at the hand lever, with a handle operating force below 6 kg for practical laboratory use.
-
Precision Die Construction: Carefully engineered tooling supports reliable forming accuracy and secure cell retention throughout the sealing cycle.
-
Rigid Corrosion-Resistant Frame: High-strength chromium steel structural components are treated with environmentally friendly electroplating and coating processes to resist rust and support long service life.
-
Compact Glovebox-Compatible Design: The small machine footprint allows installation inside a glovebox, supporting controlled-atmosphere battery assembly and sealing workflows.
-
Simple Maintenance and Operation: The compact layout, straightforward manual control, and accessible structure make daily use and routine maintenance convenient for laboratory personnel.

The standard tooling is configured for 18650 cylindrical battery third sealing. If a project requires another cylindrical cell format, optional sealing dies can be selected to match the intended battery dimensions and forming process. Pressure should be operated within the normal gauge range for standard cell sealing. When a special application requires increased pressure, the setting must be confirmed with the manufacturer before adjustment.
