What are the rebound compensation methods for sheet metal parts?
Mold repair compensation, elastic material compensation.

1. Mould trimming compensation: Trim the mould to compensate the springback of sheet metal parts. Specifically, some structures (such as protrusions or depressions) can be added or reduced on the die to change the shape of the sheet metal part and make it conform to the design.

2. Compensation of elastic materials: sheet metal parts are made of elastic materials, such as rubber and silica gel. These materials will deform under pressure, but when the pressure disappears, they will gradually return to their original state. By choosing suitable elastic material and thickness, the springback of sheet metal parts can be compensated.
