High level of Design with Fine edge Bend R

Normal bend R

Fine edge R

Big size Press brake is necessary for Hemming

High Power is required for Hemming. The tip of the hemming is swell up

V-Cut process

Acute bend

Hemming

Hemming load is only 1/3 by V-Cut

Example hemming bend with 1.5 mm stainless steel 

Load 950 kN/m ~ Height 3.23 mm

Load 300 kN/m ~ Height 2.96 mm

Effective for hole deformation and shorter flange

Normal bending = Deformation into the holes

With V-Cut = No hole deformation

1.5mm stainless steel = 7mm flange length

1.5mm stainless steel = 4mm flange length
