Tabless Cylindrical Cell Flattening Machine for 4680/ 32140/ 21700/ 18650 Battery | Kneading & End Face Shaping Equipment
Model: MR-RP-SY-21A
Products Description
Tabless Cylindrical Cell Flattening Machine (MR-RP-SY-21A)
The Tabless Cylindrical Cell Flattening Machine is specially designed for end-face shaping of tabless cylindrical lithium-ion battery cells such as 4680, 21700, 18650, 32140, and 60-series formats.
By utilizing a rotary kneading process, the machine ensures uniform electrode distribution and a flat surface, which is essential for reliable laser welding and improved current collection.
Key Features
* Suitable for multiple cylindrical cell formats (18, 21, 32, 46, 60 series)
* Rotary flattening process for uniform end-face shaping
* Automatic operation after manual loading
* High-precision positioning for consistent flattening results
* Built-in fault detection system with alarm and touchscreen display
* Open parameter settings for flexible process adjustment
* Adjustable positioning mechanism to meet different requirements
* Single-operator operation for improved efficiency

Tabless Cylindrical Cell End-Face Flattening – Before & After
Before Flattening: The end surface of the tabless cylindrical cell is uneven after winding, which may lead to poor welding contact, higher internal resistance, and increased heat generation.
After Flattening: The cell ends are uniformly flattened and shaped, ensuring even current collector distribution and optimal preparation for laser welding. This improves welding quality, reduces internal resistance, and enhances overall cell performance.
Operation Process
1. Load the cell manually into the fixture at the feeding station
2. Press the start button to initiate automatic operation
3. The transfer mechanism moves the cell to the positioning station
4. The positioning system aligns the cell automatically
5. The flattening mechanism performs the kneading process (one cell per cycle)
6. The finished cell is transferred to the unloading station
7. The operator removes the processed cell

Tabless Cylindrical Cell Manufacturing Process
Why This Machine Is Essential (Core Value)
Features of Tabless Battery Cells (e.g., 4680):
No traditional tabs
Current is conducted through the entire end surface
Problem:
The cell ends after winding are uneven
Consequences:
Poor welding contact
High internal resistance
Severe heating
Solution:
Flattening / compressing / shaping of the cell ends is required
Working Principle (How It Works)
The core mechanism is: dual-end rotation + servo pressing + roller friction forming
Process:
Place the cell into the fixture
Automatic clamping of the cell
Rotating end shaping heads start to rotate
Rollers contact the cell ends
One side rotates clockwise, the other rotates counterclockwise
Slow feeding → pressing → shaping
Final Effect:
End surfaces are flat
Current collector is evenly distributed
Ready for precise laser welding
