Anybody who know how to make hole of outer housing?

Anybody who know how to make hole of outer housing?

"Echo" has so many holes around outer housing. I guess that it is impossible to make injection mold. it looks CNC.

Please let me know how to make this hole.

Update (01/07/2018)

Thank you your reply joe.

I have already seen 'Tear-down' and disassembled it myself.

My question is how do they make the holes in the outside.

Normally it is possible to process using a CNC machine, but it is presumed that it is not the case for ' Echo '.

Considering the cost of producing the parts of product, it is probably made from plastic injection, in my guess.

please tell me know how to make this holes on outer case.

I’m sure they are using a hydraulic punch. The tube is placed on an anvil which has holes located at the different locations, the center is hollow to allow the punched pieces to fall into a scrap bin. The punch either runs a few lines or it could do all of the holes at once. Think how a paper punch works just a more powerful press.

Thank you for your reply Dan.

These days, many products have this shape.

I always wondered how to make it, but I understood a little with your help this time.

If you have information that can understand more easily, let me know.

Thank you.
