I like how you showed the alignment of the EDM electrode over the mold. That is a detail that frequently gets left out of EDM videos (but its not like there are a lot of EDM vidoes to begin with 🙂). Keep up the great content.

Yay!

Whoa!!!! You can EDM the entire part surface at once? I thought EDM was always a wire passing through. This opens a whole new dimension!

Lol... nice pun.

your videos are getting better. Thanks for putting the time into them.

It is a microscopic detailed Video, nice.

Excellent video!! Thank you!

Great video!!! Thanks!!

It feels like with this much attention required for every part, creating all the parts for an RC car would take years.

Yea but once you make the first once, you can make like a thousand a day

G'day I love watching and learning from your experiences. Totally different to my work but fascinating. I would assume the setup costs are very high (labour, materials required for mould making etc) compared to the plastics unless of course it is a long moulding run. Cheers.

Hello Friend, what's up. I'm Dionisio Veloso, from Brazil, Manaus. I'm a Jabil's employee as role plastics parts development to Air conditioners. To my new role as Tooling development engineer , these video It's so interesting. Tanks a lot.

Do you like your new boy machines? I'm lookin into purchasing a 35e and a XS boy machine.

Great "training" video. You must be right in the glide path of your local airport. Does that ever cause problems with vibration for you? Thanks for your time.

Is there any content on your channel ( or anywhere that you know of ) regarding cooling lines and how they are machined into a & B plates and also at times into the core with o rings in the inserts ? . Thanks for excellent content , even though I'm a hobby use case that could never afford injection molding I find the subject fascinating where, as with most engineering the devil is in the detail and tons of mistakes can be made if you don't have years of experience

Hi Hedley, I will make sure to cove cooling lines in my up coming mold builds. I dont have much content on them now. I usually do 2 deep drill holes through the mold block and connect them with hose. Thanks for the kind feedback

@@DragonflyEngineering thanks - this is the video where I noticed cooling channels going from the a and b plates into the cavity and core inserts . They also have a term ‘ sub inserts ‘ - kzread.info/dash/bejne/doudk9itltCzhs4.html

The leader pin pattern is offset also on the 'O' corner. Did you consider a Melt Flipper runner design for your gating?

No. That's for specific applications dummy.

I wanted to edm a knife blank, what would be the ballpark cost for etching a knife from a blank of say 300mm x 60mm x 4mm.

*38:10** How'd that plumbing work turn out? Make a video?*

EDM is one of the things that seems like it shouldn't work, but it does. But what is so unique about graphite and copper that makes them so perfectly suited for EDM? Is it the conductivity? Or the heat resistance? In that case, would tungsten carbide also work?

There really are dumb questions, and dumb people.

я бы поставил 1 000 000 лайков, если бы это было возможно ))

Why use an edm machine, why not cnc the cavities

I wanted to play with my EDM machine for the most part. thanks for watching!

You will find that most of your material and cycle time will be wasted on your poorly designed runners. Pp has the worst heat capacity . Maybe talk to a toolmaker about runners and gate location. Good luck.

Nope. The engineers do it perfectly every time, you just don't understand the physics.

If you think there is a design problem, your probably right. You're a poor design.
