Billy NANO is a prefix meaning extremely small. The Symbol is = n

Examples are nanofossil - nanotechnology -
nanomoulding

Haven't heard of nanoextrusion, but did extrude a 0.006 ID x 0.009 OD fluorocarbon tube used in a blood gas analyzer machine. That was back in 1976 before NANO became popular as a prefix. We got by with single syllable words back then, like "small."

Do you have any experience in this type of injection moulding? How do you machine this nano cavities?

We have injection molded parts as small as .27 gr. We do not publish our methods for the tooling of these tiny parts as we consider it proprietary. :)

I guess this machining is done by lasers or electrons...

Billy,
Machining is done verry carefully.

billy,
you must first assemble these little teeennny robots that have little teeennny walkie talkies so that you can communicate your wishes to them.
Then you instruct them to make wicked teeennny little lathes, three axis millers, grinders and EDMs (ooops,) edms.
then they. Wait, no, no, first you must remember to whisper into the walkie talkies so as not to hurt their wittle little ears.
then...........

I'll let the other guys finish this fairy tale

lets master "micro molding" first before we invent new tortures for moldmakers.

j:D

Billy,

How are electrons used in mold making?:confused:

Al,
can I answer?
we use photons (similar) in laser milling
and we use the heavier guys Protons and such in plasma cutting.
we also use electrons to create fields that push our motors around in milling machines:D

When moderators get the power to move threads to the appropriate forums, I think I will move this one to the <b>Silly Poly Questions</b> forum. It's reached it's critical silly mass :)

I am aware of micro (10 <sup>-6</sup>) injection moulding where the components are of a size that you will get two per polymer granule.

You are talking about nano (10 <sup>-9</sup>) injection moulding - that is 1000 times smaller. What kind of components are these that you will get 2000 of them per granule?

Nanomolding is a new one on me.

Micromolding is a term in common use to describe injection molding of very small parts weighing a fraction of a gram, and the prefix 'micro' strictly means one millionth. As Peter points out, 'nano' means one billionth - a thousand times smaller. So if logic has anything to do with it, nanomolding should refer to molding parts that are very small compared even to micromoldings. The only thing I can think of that qualifies is LIGA technology. This predates micromolding; it has been around since the 1980s. Maybe it is being retrospectively dubbed nanomolding to aviod confusion with micromolding. Or maybe a marketing manager is moving in.

There is a reasonable amount of information about LIGA on the web, for example at <a href="http://www.imm-mainz.de/content.html" target="_blank">The Institute of Microtechnology Mainz</a>, <a href="http://www.sei.co.jp/RandD/harima/ligatech/ligatech.htm" target="_blank">Sumitomo Electric</a>, <a href="http://daytona.ca.sandia.gov/LIGA/tech.html" target="_blank">Sandia National Laboratories</a> and <a href="http://www.microparts.de/english/index.html" target="_blank">Steag</a>.
