The force must exceed the material s yield strength to achieve a plastic deformation.
Binding sheet metal to hard plastioc.
You can see this in the fogging of some clear plastics on the outside surface.
Bend the metal with your mallet.
Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.
This is done through the application of force on a workpiece.
All this occurs on a molecular level.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
Holding the sheet material evenly with both hands both in protective gloves push the sheet up gently bending it against the line of the jig as shown in the photo above.
To prevent damage or unsightly dents it s best to use a rubber plastic or rawhide mallet to gently tap the metal.
When a bend is made in sheet metal or plastic the outside of the material structure expands while the inside compresses.
Do this until it bends toward the form block and achieves your desired angle gradually and evenly.
Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.
