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.

* Multiply x 1.5 to above figure for stainless steel, and x 0.6 to Al A5052.

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.
