AI Overview
Pneumatic sealing machines for batteries are specialized tools used primarily in laboratory research and small-batch production to seal battery casings securely. They utilize compressed air or inert gas cylinders to drive a cylinder that crimps, seals, or hot-presses battery components, such as cylindrical cells (18650, 21700) or pouch cells, ensuring an airtight, leak-proof finish.
Here are the main types and key examples based on battery type:
1. Pneumatic Sealing Machines for Cylindrical Cells
These are designed for sealing the cap on cylindrical cans (e.g., 18650, 26650, 32650) after electrolyte filling.
- MSE PRO Pneumatic Sealing Machine (BR0448): A compact machine suitable for inside a glove box, offering a max sealing pressure of 1 MPa, with a 30 mm sealing trip.
- AOT-QF650 Pneumatic Sealing Machine: Features two-step sealing for better performance, with a 0.6–0.8 MPa gas supply and a weight of 34 kg.
2. Pneumatic Sealing Machines for Pouch Cells
These machines, often called vacuum sealers or heat sealers, are used for sealing the sides and top of soft-pack batteries.
- MSE PRO All-in-One Sealing Machine (BR0332): Combines vacuum, electrolyte degassing, and final sealing. It has a sealing temperature range of Room Temperature (RT)–250°C.
- ACEY-VPS200 Pouch Cell Vacuum Pre-sealing Machine: A pneumatic, heat-sealing device for small-medium pouch cells, capable of operating in a glove box, with a 200 mm length sealing head.
3. Pneumatic Sealing Machines for Coin/Button Cells
These are used for crimping and sealing button cell batteries (CR2016, CR2032, etc.).
- Labideal Coin Cell Pneumatic Sealing Machine: Provides electric/pneumatic, effortless operation with high-precision positioning for consistent sealing height.
- Xmacey Pneumatic Sealing Machine for Button Battery: Designed for lab R&D, these machines are compatible with inert gas, preventing contamination in the atmosphere of the glove box.
Key Features and Specifications
- Glove Box Compatibility: Compact designs are generally designed to fit inside argon or nitrogen glove boxes to maintain low moisture/oxygen levels.
- Gas Supply: Driven by 0.6–0.8 MPa compressed air or inert gas cylinders.
- Accuracy: Sealing pressure typically features an accuracy within .
- Safety: Most machines are equipped with protection features like safety curtains or two-button operation.
- Modular Molds: Many machines allow for custom or interchangeable dies to accommodate different battery sizes (e.g., swapping between 18650 and 21700).
