As shown in Figure 3, holes in the direction of shorter sides of the plate show a zigzag pattern, and the longer sides are feed direction.
Figure 4 shows a punching method different from that in Figure 3.

In the case of series punching, if the hole interval has no problem, a one-line mold is used as shown in Figure 5.
When the pitch is extremely narrow because of the relation between plate thickness and holes, processing may be difficult. In such a case, we use a skipping-type mold as shown in the figure before punching. Even after skipping-type punching, it is possible to manually fill holes to create a non-skipping pattern.

After punching, it is possible to maintain margins at the edges of the material.
There is a case where four margins remain at the four sides of the material and a case where margins remain partially such as in width direction.
Regarding margin size, please designate the distance from hole edge to material edge or from hole center to material edge. It may be necessary to modify size requested by customer because of limitation in terms of mold size or punching pattern.
