Common repair methods of car body depression in automotive sheet metal;

One: hammering is a common treatment method to repair concave-convex deformation. For the deformation, indentation and bending of column parts, tools such as wood block, mallet, pry plate, hammer and jacking iron can be used flexibly to directly knock the deformed parts to reset them. The pry plate is beneficial to the dressing of leather parts. For weak parts, you must choose wooden mats or mallets and rubber hammers, so as to avoid secondary injuries caused by the repair of body parts.

The other: suction method and manual traction method, in which the deformed part is firmly sucked on the outside by vacuum sucker and pulled back by hand or inertia hammer. There is also an electromagnetic sucker that has the same function. Use a manual lever to correct and reset local depressions. This method not only avoids the trouble of disassembling and assembling the inner panel, interior decoration, door and window roller, but also reduces the damaged surface.
