Sheet metal process hole is to not to pull material, in the process of sheet metal bending when sheet metal bending line across the point or line of sheet metal bending and sheet metal edge closer to and smaller than 2 times of thickness, the need to increase the sheet metal bending process hole to avoid bending puller, hole bending process is generally used in bending of sheet metal pieces of the package edge, edge bending is not package, can need not open hole.

If you want to know more details, we are glad to tell you.Supported by ingenious team, Bergek CNC has highly recommended service team.
Do not open the disadvantages of the process hole: so that the edge will be less material thickness, welding filler, but also easy to cause welding deformation.
Advantages of open process hole: in the case of wrapping, the bending process hole can make the wrapping edge smoothly bend in place, and not bend and pull material.

How to determine the size of the process hole?
The size of the sheet metal process hole depends on the position of the process hole. If the process hole is at the intersection of two lines, the process hole is 2 times the thickness of the plate. The minimum sheet metal thickness must be 1.5 times. Sheet metal thick plate bending, considering bending rounded corner, the process hole should be appropriately increased.
The shortcomings of this process hole: the process hole made in this way, after bending, especially thick plate, bending Angle deficit is very serious, not beautiful and not good welding. At this time, it is necessary to improve the method of making process holes.
Optimization method of process hole:
Can be determined according to the bending side of the bag, considering the
thickness of the plate, bending round corner to determine the sheet metal
