Burr-free Type

When an element (aluminum foil) is wound around the lead terminal, the element is sometimes torn off at the point contacting with the corner of the lead terminal.

Kohoku Kogyo has improved the press process and achieved the production method that does not occurr burrs on the corners of the lead terminal during punching.

When a comparison is made between the sectional views, spiny burrs are generated on the corner of the standard type (upper), but no burr is occurred on any corner of the burr-free type (lower).
