Pneumatic Coin Cell Crimping Machine

1. Product Introduction

Mainly used for laboratory battery material R&D sample preparation to assemble coin cells, capacitor cases, and also for small-scale pilot production in factories. With different molds, it can also be used for battery disassembly, electrode sheet pressing, and battery powder pellet pressing.

2. Standard Mold Configuration

Equipped with a standard mold for CR20 series coin cells. By replacing some mold components, it can also be used to seal CR16, CR24, CR30 series coin cells, etc.

3. Main Features

◎ The lower mold adopts a high-precision limit ring to control the sealing height of the battery cell, preventing excessive or unstable sealing pressure that may damage the cell or sealing cup;
◎ The upper mold and inner ring adopt a screw-spring ejection structure to ensure that the cell is not stuck inside the mold after sealing; it can be easily removed by turning the top screw knob;
◎ The crimping air supply can be provided by either gas cylinders or compressors, and the exhaust design prevents damage to glove boxes;
◎ Precision-designed molds ensure reliable sealing and forming accuracy. The robust steel structure design ensures stability and safety during use;
◎ Purely pneumatic operation, no electricity required, easy to operate and convenient.

4. Technical Specifications
