MSK-PN510 Pneumatic Crimping Machine for Cylindrical Battery Cases
The MSK-PN510 is engineered to perform precise crimping and sealing of cylindrical battery cases, a critical step in battery assembly and packaging. It is particularly suited for sealing 18650 battery cases using its standard die, with the flexibility to accommodate other cylindrical cell sizes such as 21700, 26650, and 32650 by replacing the crimping dies. This machine is ideal for laboratory and small-scale production environments where consistent, wrinkle-free seals are required.
The crimping process is powered by a pneumatic cylinder, which provides adjustable sealing pressure controlled manually via a valve. The maximum pressure is 1 MPa, with a recommended operating pressure of 0.7 MPa and an accuracy of ±0.5%. The machine is designed to operate with compressed dry air or inert gases such as argon or nitrogen, especially when used inside glove boxes to maintain atmosphere purity. The built-in pressure gauge ensures consistent pressure during operation.
Key Features
- Compact and lightweight design suitable for glove box integration through front window access.
- Pneumatic cylinder-driven sealing die with adjustable pressure for precise crimping.
- Standard 18650 crimping die included; optional dies available for CR123, 21700, 26650, 32650, AA, and AAA sizes.
- Pure pneumatic operation without electrical components, enhancing safety and ease of use.
- Built-in pressure gauge to monitor and maintain consistent sealing pressure.
- Recommended use of high purity inert gases inside glove boxes to preserve atmosphere integrity.
- Two-step precision crimping dies available for wrinkle-free sealing on 18650 and 21700 batteries (MSK-510M update).

Typical Applications
The MSK-PN510 is used primarily for sealing cylindrical battery cases in battery research and development labs, pilot production lines, and quality control processes. It is essential for preparing battery cases before cell assembly, ensuring airtight and wrinkle-free seals that maintain battery integrity and safety.
Configuration & Operating Notes
The machine includes the standard 18650 crimping die; other dies must be ordered separately and installed by qualified personnel to avoid damage. It is necessary to groove the cylindrical case opening using a compatible grooving machine (e.g., MSK-500) before crimping. When operating inside a glove box, use high purity inert gases such as argon to maintain atmosphere purity. If using a gas cylinder instead of an air compressor, a two-stage pressure regulator must be installed to ensure safe and consistent pressure. Hydraulic crimpers are not recommended inside glove boxes due to potential oil leakage.
