Help Needed Metalworking Question

Hello All,

I'm working on 18 ga. sheet metal project where a stamped recess in the sheet metal has become distorted and flattened (no recess). I would like to know how I can restore the recess back into the sheet metal. The recess dimensions are approximately 1 1/8" x 1 1/4". I've attached photos showing the damaged flattened recess and an undamaged recess. Any help is appreciated.

thank you

cross

It looks like the material has been worked and stretched. The problem is the more hammering or bending you do the more it stretches the metal and makes it curl like a potato chip. There are metal shrinking tools but it's best to avoid the situation in the first place since it's difficult to remove.

You would need to make a frame of heavy steel around the perimeter then using a hammer and metal block force the metal down.

Not to difficult to do but making the tools to form will take more time than the repair.

Many solutions depending on how much one wants to spend. What function does the recess area perform that you are trying to straighten out the sheet metal distorted by heat and pressure?
