Understanding Springback; Material Selection - Baileigh Industrial HSP-30M Operator's Manual

UNDERSTANDING SPRINGBACK

Springback, also known as elastic recovery, is the result of the metal wanting to return to its
original shape after undergoing compression and stretch. After the bending leaf is removed from
the metal and the load is released, the piece part relaxes, forcing the bent portion of the metal to
return slightly to its original shape. The key to obtaining the correct bend angle is to over bend
the metal a little and allow it to spring back to the desired angle. All metals exhibit a certain
amount of spring back.

MATERIAL SELECTION

CAUTION:
processed through the machine are NOT potentially hazardous to operator or
personnel working nearby.
When selecting materials keep these instructions in mind:
 Material must be clean and dry. (without oil)
 Material should have a smooth surface so it processes easily.
 Dimensional properties of material must be consistent and not exceed the machine capacity
values.
 Chemical structure of material must be consistent.
 Buy certificated steel from the same vendor when possible.
It must be determined by the customer that materials being
