R-Bend Urethane Type
SPCC : 0.6 - 2.3mm SUS : 0.6 - 2.0mm
This urethane die is suitable for larger R bending. No marring appears on the component surface and helps prevent multiple-breakage. Also this tool has versatility and cost-performance because only punch is replaced for required radius.

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
No marring appears.
Check Machine Capacity
Be sure that required tonnage gained by equation above does not exceed the machine capacity.
Selection judgment
When urethane is selected product Inner Radius >30.
