How do they put the flux in solder?

[tub...@myshop.com]

I have a box of 18 gauge solder that says it has 5 cores. Putting one
core in solder that thin seems impossible. and this has five. How do
they make it?

[Rheilly Phoull]

Google "Extrusion"

A lot like putting stripes on toothpaste, which is also clearly impossible.

I don't actually know, but I'm wondering if it is done by starting with a
big bar and then rolling and stretching it, kind of like wire drawing.
It seems extrusion won't work, as that would leave the holes in the
solder wire empty. But, maybe there's a trick to it. The nozzles that
fill the holes would have to be REALLY tiny, and then hollow for the flux?
Seems like it would never work.

I'm still trying to figure out how they put the filling in the Cadbury
Caramel bars...

It starts, as you suggest, as a much larger tube, and then is drawn to the correct diameter.

https://static.makeuseof.com/wp-content/uploads/2015/04/rosin-core-solder-640x240.jpg Is a picture of single-core solder. 5-core takes a little bit more care, and will not be possible with the more brittle formulas.

The key is keeping the tin/lead admixture annealed during the entire drawing process, yet not so warm as to melt. Noble metals do much better at this than others, and lead is very nearly a metaloid in any case - so this is not a casual exercise. The multiple cores serve to spread the rosin more evenly, so it is not just hype.

Form the caramel bars, freeze them, dip in a vat of hot chocolate and lay
flat on a cold surface until set?

There was an musical ad in the 70s that asked that question as I
recall...but I can't remember how it went other something like "How do
they put the caramel in Cadbury's bar?"

"An enrober operates by first dipping the bottom part of a confection in a bath of liquid (chocolate is the primary coating used with such equipment). The item then passes through a curtain of liquid to complete the task."

[Martin Gregorie]

Yes, that makes sense, both as a way to get a coating on the underside
and of the shape or the top and side coating.

Do you know whether the core needs to be chilled? I'm just thinking that
some fillings are very soft and that chilling them would stop them
deforming while being coated and then while the chocolate is setting.

[tabb...@gmail.com]

Some fillings are chilled - ice cream certainly has to be

As interesting as all this confectioners lore is, it has
absolutely NOTHING to do with flux cored solder....

I don't think that's true. Why, just the other day I was brushing my
teeth with striped toothpaste after eating some some hard candy discs
that had a valentine heart shape that went clean through the candy and
it got me to thinking about multi core solder and how they make the
stuff. So there.

AFAIK the two usual methods for that sort of job are co-extrusion (as in
Blackpool Rock candy sticks, where the writing went all the way through
from one end to the other) and drawing down a preform through a
succession of wire dies. For solder, drawing down would be my guess.

This sort of gets off the topic of solder, but others explained that
fairly well. however I imagine they fill the candy the same way jelly
filled donut (sweet rolls) are filled. I once asked a baker how they do
it, and he said it's injected with a device similar to a syringe. A
plastic point is shoved into the donut and the jelly injected.

A large object like a donut or candy seems a lot more easy than that
thin solder.

That's exactly how flux cored solder is made. Same for hypodermic
tubing. Similar process for the very small diameter glass tubing used
for injecting stuff into living cells. Except the glass is just drawn
out from a larger tube, it doesn't go through a die.

I believe your guess is correct. I saw a marketing blurb by Ersin
Multicore, talking about their process, and they specifically
mentioned the use of a progressively-smaller series of dies.

They said that some "fake" multi-core solder (by their competitors)
uses a single nozzle with five openings to extrude the flux. Although
they didn't say so specifically, this implies to me that their own
process uses five separate nozzles as part of the initial extrusion
process.

there's more than 1 way to interpret that.

surely it doesn't imply that. Any why and in what sense would another mfrs 5 core solder be 'fake'?

I often care less about the how than I am about the "who"..

For example, who put the ram in the rama lama ding dong?

And here lies the problem. Far too much reality shows on TV, and every
other craft television show is made intentionally (well, at least here
in the UK) devoid of technical content, so the audience can be shown yet
another "who" instead of "how". Andy Warhol was right.

I hope you're not suggesting that the UK has more mindless drivel "reality" shows than we do here in the Colonies. Them's fighting words.

**Cadbury chocolate. :PUKE:
Not the worst chocolate on the planet (that honour goes to Hershey, or
some of the Asian makers), but not far behind. They generally make
pretty decent TV ads though. Gotta give 'em that. Loved the gorilla one.
