Equipment Description
This equipment is mainly used for the pressure testing of cylindrical-battery combination caps and the air-tightness inspection of the sealed cap-to-can joint. Test functions include: air-tightness testing (measuring the pressure value of the cap and the sealed head), pull-strength testing of the welded joint between the cap connector and the explosion-proof disc, and printing of the test results.
