Tension correction：The shape of the processed substrate is poor, such as in the middle of the wave edge

Function: To make the plate shape flat

Electrostatic oiling：

Apply electrostatic oil to the tinplate sheets after production to prevent rusting and transportation scratches

Pinhole detector:

Both the tin plating production line and the shearing production line are equipped with pinhole testers, which can detect pinhole problems on the tinplate surface during the production process and select problematic tinplate
