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.
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.
