Correct.



It is because while steel melts at much higher temperatures; aluminum conducts electricity much better than steel. When you heat metal with induction, you can essentially think of the...

Induction generators will have different rated capacities based on the metal intended to be melted.

They sell the generator - its up to you to make the work coil and size the crucible, etc. -...

Quite true. Casting large items still involves its own work as well though - more hands on than running a robot unless you are the big foundries that do use plenty of automation.



Below is a...

I believe they call it 15KW because that is how much power is in the work coil at resonance.

That said, mine will even pull 45 amps running at 240V - that is over 10KW.

I have no idea about the...

I mostly use it for carving out EPS foam and wood for patterns for metal casting.

It will also machine aluminum if I am not in too much of a hurry.

Let me know if you need anything big carved!...

Well if people are going to ignore the warnings there, people are going to ignore them elsewhere too I suppose.


The point I have been trying to make, is, I wasn’t like look just stick something...

Actually swashing around 700 amps in the primary coil and many thousands of amps in the secondary (work) coil at 30-85 thousand times a second at 230 V input without blowing up is quite...

Actually - I won't tell anyone to duplicate my efforts - that isn't the purpose of the video. The description for the video reads in part: "WARNING: This is for informational purposes only. Fire,...

A 15KW or more powerful one? I would like to see that!

I've only see toy sized ones "easily" made. The amount of hardware alone needed to build a 15KW induction furnace is anything but trivial.

My point is there is a lot more to it than someone just seeing a video like this and duplicating my efforts. They are going to have set out to make a whole foundry. It can't just be copied on a whim....

It is an informational video of what we do here. We go out of our way to discourage others from trying it at home.

How many of these people that you have in mind, just happen to have an induction...

For staters they are sand castings - which will never quite have the same detail as investment castings. You are incorrect about any crisp detail being lost - many of the original print lines are...

That is correct as well.



The the pour tube is called a "Sprue". It is both tapered and oversized to help build up as much hydrostatic pressure as possible (also makes it easier to pour into)....

Thank you!

What is different is that with traditional sand casting the pattern is removed from the sand before the metal is poured. Since it has to be removable without damaging the fragile sand...
