New Product Development: Drilling thin laminate question

Jan 31, 2006 9 Replies

Hello everyone,



I am currently working an developing a new house hold product. The product is in Patent Pending status.



I am interested in locating a manufacturer (preferably close to Atlanta) that has the capability to drill a field of holes in a very thin laminate described below: Simply stated, the laminate is "plastic coated aluminum foil".



Top Layer: Plastic: 0.85 - 2 mil thickness. I have built prototypes using both 0.85 and 2 mil plastic. The source of the 0.85 mil plastic is the standard "generic" garbage bag - just to give you an idea of the type of plastic I'm using.



Center Layer: 0.93 mil +/- 10%. This is standard heavy duty aluminum foil.



Bottom Layer: Same as Top Layer.



In the perfect world, the laminate would be available in roll format. Perhaps there is a machine that would pull the laminate from the roll while drilling.



Alternatively, the laminate could be cut down into individual sheets that could be fed to a machine that would drill each sheet ... or several sheets could be stacked on top of each other and drilled through - it all depends on the drilling machine.



The perfect width of the laminate is 17 inches. The field of holes is at least 10 1/2 inches wide, which could run the entire length of the laminate. The field of holes is centered, so there is approximately 3



1/4 inches of undrilled laminate on each side.

The diameter of each hole is 1/8 inch. The spacing between holes in approximately 1/2 inch.



Any thoughts, advice, etc. is sincerely appreciated. I will also be happy to answer questions that would not require a non-disclosure agreement.



Thanks in advance!

Seems like you need a hole puncher, not an actual drilling. Hole punchers can make cleaner holes in thin materials like such drills can get pretty messy on such thin material.

I am sorry to say, I do not know companies that offer such a service. It seems it may be up to you. :(

Hmmm...looks like you disclosed the idea. Anyway - there's a high volume method - feed through a roll with dies and a roll with punches in register to pop all the holes at once, or as a slow speed prototype use a row of dies, with a row of punches - perforate and step on.

Brian Whatcott Altus OK

Any Printed Circuit Board shop can do that kind of work

This method sounds very interesting - greatly appreciated. --Ed

Thanks for the thought on hole punchers. I agree that drilling is not as clean, and even at slow RPM (about 5000) I still see (although very infrequently) some evidence of melting. Should have seen the first prototype get destroyed when drilling at 30000 RPM - LOL! I also attribute the destruction to using an inferior adhesive, but I learned from that one.

Very interesting - never would have thought have that! Thanks, --Ed

Really??? I never would have thought of that... Thanks! --Ed

Ed, There are a lot of companies that specialize in custom perforating metals and plastics. A few examples are:

There may be a company in the Atlanta area that can produce your prototype. Go to

and search under "Plastics: Perforated" or "Metals: Perforated".

You might also get lucky and find a company that already has a suitable perforated plastic/metal laminate in stock!

Good Luck
