MSK-510L is one set (2 units) of hydraulic crimpers for sealing a large diameter of the cylindrical cell, such as 4680, 4695, 46100, 46120, and 50100. Two sealing machines are included for three times sealing. Video: How Tesla make 4680 cell The first crimping machine is used for the cap crimping and smooth edgesThe second crimping machine is used for height and edge adjustment, which will make perfect sealing for cylindrical cells. The compact design allows it to be easily placed inside a glove box and thus preventing contamination of the electrolyte materials during cell assembly. Simple operation with a safety protection feature allows customers to master the sealing procedure within 5 minutes.
