Can you add a hole to this finding
We can almost always add a hole to our findings, the question really is can
we add a hole the size, location, and quality that you need, in a manner that is
cost effective enough for you to use the particular finding in question to
solve your design and production problems, and the answer to this question
is...sometimes yes, sometimes, no.
- First let's deal with the size of the hole and the size limitations. It is
not effective to add a hole to a finding with the punching or piercing
method with a hole diameter that is less than the material is thick. For
example: if the finding is made of .025 material, you cannot add a hole of
.025 diameter. You could add a hole of .027 diameter, or you could add a
hole of .032 diameter, but not .024, .025, .020.
- The next concern is where on the finding you need the hole added. If the
surface front and back is flat where you want to add the hole, then
generally there is no problem. However when this is not the case when the
punch is driven through the piece into air before above the die you risk the
chance of the piece collapsing. Occasionally the piece is structured as such
that it will not collapse under the pressure of the piercing of the hole but
you will end up with an enlarged burr on the back of the piece.
- If you should decide to punch a hole from the back of the piece to the
front of the piece, in order to gain the support of the die, you may not
crush the piece, but you’re still going to have a burr, only this time the
burr will appear on the front or the embossed part of the piece.
So...how’s that for a complex answer to a simple question? In essence it's
almost impossible to answer this question in a broad, general terms. However, if
you have a specific finding and a specific hole size and location in mind, give
us a call. We’ll be glad to work out a quote and specifics with you.
