This machine is used for sealing coin cells and capacitors in laboratory R&D sample preparation and factory small-batch trial production. Equipped with interchangeable molds, it also supports cell disassembly, electrode pressing and powder cake forming.

Key Features

Lower die fitted with a high-precision positioning ring to limit sealing height and prevent damage to cells and sealing cups caused by unstable excessive pressure
Screw spring ejector mechanism inside the upper sealing cup; stuck coin cells can be ejected by turning the top screw
Dual air supply modes: compressed air or inert gas cylinder; external exhaust design avoids contamination of the glove box atmosphere
Precision molds deliver accurate and reliable sealing; solid steel frame ensures stable and safe operation
Fully pneumatic operation without power supply for convenient use
Operates under an air pressure of 0.4 MPa for sealing
