[Industry/Application]
Electrical parts (for mass production)
Automotive keyless button battery parts

[Feature]
As shown in the photo, the terminal part is thin and only about 0.7mm wide.
Since it is a battery terminal, the dimensions must be stabilized because the grounding to the button battery will be uneven if the variation, such as spring back, is not suppressed.
Furthermore, this is a button battery part for automotive keyless entry. After plating, the assembly is performed on the molded product and delivered in a specific tray.
This product is plated by a cooperating company and inserted into the molded product in-house after progressive press working.

In addition to pressed products, We can also deliver molded products through integrated production by utilizing our entire network.
