MSK510L-4680 Hydraulic Sealing Machine for 46 mm Diameter Cylindrical Cells
The MSK510L-4680 is engineered specifically for the hydraulic sealing of large-diameter cylindrical battery cells such as 4680, 46100, and 46120 formats. This equipment addresses the critical need for reliable and contamination-free sealing of cylindrical cells during battery assembly, particularly in research and development environments.
The system comprises two separate hydraulic crimping units that perform a three-stage sealing process. The first unit performs initial cap crimping and edge smoothing, while the second unit adjusts the height and edge to ensure a perfect seal. Its compact footprint allows placement inside a glove box, minimizing electrolyte contamination risks. Operation is manual with hydraulic pressing force up to 5 tons, and the crimping pressure is adjustable between 80 and 1000 kg/cm².
Key Features
- Dual hydraulic crimpers included for a three-step sealing process enhancing seal quality.
- Manual hydraulic pressing with maximum force of 5 tons for precise control.
- Adjustable crimping pressure range from 80 to 1000 kg/cm² to accommodate various cell specifications.
- Crimping dies made of SUS 304 stainless steel with hardness ≥ HRC 58 for durability.
- Compact design suitable for glove box integration to prevent electrolyte contamination.
- Maximum crimping distance of 40 mm to support thick cell caps.
- CE certified; no electrical components, so NRTL certification is not required.

Typical Applications
This sealing machine is ideal for battery R&D labs and pilot production lines working with large cylindrical cells such as 4680 and related formats. It ensures consistent, contamination-free sealing critical for cell performance and safety testing.
Configuration & Operating Notes
Before sealing, the cylindrical cell case opening must be grooved using the MSK-500L grooving machine to prepare the cell for crimping. Each cell type requires a specific crimping die set; users should select the appropriate die model for their cell format. The equipment includes two crimping units but crimping dies for different cell sizes are optional and must be ordered separately. The manual hydraulic operation includes safety protection features for user convenience and quick mastery of the sealing process.
