Description
Pneumatic Punching Machine – Lab Electrode & Separator Puncher for Glove Box
The Pneumatic Punching Machine is a precision slicing equipment developed specifically for punching and cutting various materials in the battery research and production industry. It is designed to punch lithium battery cathodes, anodes, and separators with high accuracy and minimal burr formation.
Working Principle:
The material (electrode or separator) is placed on the lower cutting platform. Stepping on the foot valve activates the pneumatic system, causing the upper die to descend and punch through the material in a single, clean motion. The equipment returns to its ready position automatically after each cycle.
Key Features:
- Precision Cutting: Fine workmanship ensures minimal burrs and no indentation after punching.
- Versatile Die Compatibility: Interchangeable dies from Ø8mm to Ø24mm accommodate various battery sizes and components.
- Glove Box Compatible: Compact design (L110×W170×H380mm) allows easy placement inside standard glove boxes.
- Pure Pneumatic Operation: No electricity required; foot valve control for safe, hands-free operation.
- Easy Die Changes: Simple installation, disassembly, and replacement of dies.
- Durable Construction: Main materials SKD11 hardened steel for long-lasting precision.
- Compact & Portable: Small footprint, lightweight (13kg), easy to clean and maintain.
Die Selection Guide:
- Ø15mm – CR20xx series coin cell electrodes
- Ø19mm – CR20xx series coin cell cases & CR2325 anode electrodes
- Ø20mm – CR2450 electrodes, CR2325 cathode electrodes, CR20xx separators
