Shear is good for reduce tonnage, reduce slug pulling and reduce noise.

Flat punch tip (no shear) is fine for A and B station tool since tonnage would be small. For blanking process, flat punch tip should be used.

Slug ejector

The slug ejector is good for slug pulling problem.

It will be installed to over Ø4 for RO and over 6 width for shaped as our standard.
Please process without slug ejector when processing thick sheet with small punch dimension. In that case, please instruct us "No need slug ejector".
