Off-set Up-Spring Type

SPCC : 0.6 - 2.3mm SUS : 0.6 - 1.5mm

Relatively larger off-set is created by one operation. One operation creates 2 bends together and this saves material Lturn-over and one bend. There is no limit for the flange length.

Necessary Tonnage Calculation

SPCC Tonnage /m above x1.0 x product length(mm)÷1000
SUS Tonnage /m above x1.5 x product length(mm)÷1000
AL Tonnage /m above x0.6 x product length(mm)÷1000

Cautions

Marring

Marring appears on both sides.

Off-set Up-Spring Type Slide Marring

Check Machine Capacity

Be sure that required tonnage gained by equation above does not exceed the machine capacity.

Product Accuracy

Product height accuracy becomes ± 0.2mm.
