How It Works
Functioning as a precise mold, the KINTEK sealing die applies controlled pressure to compress and hermetically seal button battery components. This process is crucial for protecting the battery's internal materials from environmental factors and maintaining its structural integrity, leading to optimal performance and safety. Its robust design also allows for the careful dismantling of cells when analysis or component recovery is required.
Operation Steps (Sealing & Dismantling)

1. Assemble the case of the button cell.

2. Put the assembled button cell in the hole in the packing die.

3. Put on the flat punch.

4. Put the die in the hydraulic press.

5. Increase the pressure to about 1000kg for sealing.

6. Take out the packed button cell.

7. For dismantling, place the button cell in the die's disassembly hole.

8. Put on the tapered punch for dismantling.

9. Increase pressure to about 400 kg for dismantling.

10. Take out the disassembled button cell components.
