Injection molding setup and run

[@AbhishekThakur-uo6il]

Thanks for sharing such detailed demonstration. A must watch for beginner injection molders!

[@Jeremy-iv9bc]

Man you have all the coolest toys.

[@alex_yates]

Great video. Thanks for sharing. It looked like you could've used an extra pair of hands mounting it to the machine 😂

[@pauldeeley669]

My dad was a technical service rep. for bulk molding compounds for Cyanamid, later sold to Rohm, back in the 70s and 80s. Interesting to see some of what he was involved in doing back in the day.

[@OscarFlores-gh2bs]

Blondi... sent me too 10 years molding exp. bring back memories 15 years back. Used van dorn machines.Plastic and Rubber.

[@serro_1990]

very lovely machine and a very in-depth informative video, well done! Hope to see more videos with setup's for different moulders

[@paulmace7910]

Would love to see more on mold design and fab. Robots, robots, robots.

[@KRSbumpbars]

couple of questions; 1. You pull the injector back with each shot, why not leave it against the mold? 2. Where do you establish a two hit on the ejector pin cycle? Great video series! - Kevin

[@DragonflyEngineering]

A few resons for 1, sometime the nozzle of the injection unit cools off when in contact with colder mold, it also breaks a plastic stringer that can follow the sprue out of the mold, it also helps with excess drool, sometime you want to break away from the sprue so a disk of plastic doesn't form a hole the sprue in place. 2, the multi eject is called different things in dif machines, but in the ejector page of you controller you can set the number of eject cycles, usually with delays etc, the Hitian calles it "vibrate" mode. Thanks for watching!

[@djwmunro]

Wow I learned so much about a process that we all depend on for all our modern stuff. Thanks for the great vid.

[@DragonflyEngineering]

Thanks David!

[@DudleyToolwright]

Fantastic. I'm totally hooked. I hope you do more molding videos in the future.

[@DragonflyEngineering]

The next one is a mold, just finished the molding run!

[@andresl.2641]

The best part is your machine it´s a beautiful BOY!!!! Thanks for share!

[@kichilllee]

Thanks for sharing and this is really good for us to easy know the details about this moulding industure, and we do the molding builing as well but very bigger for BMW ,VW etc ,and now we running PHILIPS items also , so I can learning from you 'dragonfly' ALSO ~~ CHEERS ~~

[@DragonflyEngineering]

Great, I'm glad you like the content. Thanks for watching. The next video is a mold too!

[@lucasflowers88]

This is awesome, I work in plastic injection molding. Thought this was cool

[@rantimijohnson9269]

This video was so helpful In my current research work in working with Boy 25e. My problem was the plasticizing screw wasn’t moving forward when I set it on semi automatic or automatic mode. Can you tell me what was wrong, please. Thanks.

[@DragonflyEngineering]

glad to help

[@luispalafox3821]

Great video and explanation Congrats !!!

[@nidhinfrancis123]

Nice efforts ❤

[@bhupeshgujrathi3265]

Very informative video. Thank you for detailed explanation!!

[@lexpro2239]

Your assistant lol Thanks for the video

[@nghia222]

Very helpful video but i have some concerns: during automatic mold, the injection unit keeps moving back and forth every cycle, why dont you keep it in the advance position always? and if it keeps repeating that does it have any bad effect to the nozzle or sprue bushing of the mold?

[@dharmendrakumartyagi4568]

Please make a video series on hot runner mold, I really need to understand about it .

[@dharmendrakumartyagi4568]

I also want to know that, does we have to do something with nozzle before starting or use it as it is.

[@outsidescrewball]

Great video...discussion/demonstration....very interesting

[@thayalanananthamoorthi4663]

Can you upload the kraussmaffei and the robots ?

[@NkosinathiMadondo-v6j]

Thanks for video

[@claster-mars]

what material was spilled? (transparent )

[@robertbushong1751]

Very interesting. Off subject, did you have relatives who worked in Honduras?

[@DragonflyEngineering]

Thanks, I'm also from Ohio, USA

[@urcdude]

Great video, very interesting... i need one of these !

[@ranieledasilvasantosroni8693]

[@iqbalmann4534]

Is cushion same as decompression ?

[@stgtvnews]

make bigger parts?

[@plasticman3952]

What's the temperature of the mold?

[@cornoadmin]

Why do you have to be so careful about squareness and perfect dimensions when you are just going to clamp the mold between those heat isolation pads that have to be at least a little bit conformable?

[@DragonflyEngineering]

the thermal isolators are pretty hard woven glass and epoxy, so they dont squish much. The big concern is the 6inch width of the mold, that length adds up and the lever action tipples the out of square that the machine tie rods see, so the rod seals will fail sooner from the tie rods in the machine being bent off axis. Thanks for watching

[@dwaynesykes694]

@@DragonflyEngineering stick one of those thermal isolators on the surface plate and check it. I suspect they're off by more than a thou over the same distance. I understand and fully support minimizing misalignment whenever and wherever possible, so I'm not criticizing the work on the mold like the original commenter, but instead wondering if there are more precise thermal isolation options? Perhaps phenolic composite (e.g. Garolite CE) checked/machined for flatness?

[@themotoworksinc5702]

can you recommend any books to learn how to run a machine like this? I am working on some molds for small plastic parts, having trouble finding shops willing to run them, and looking into getting a small machine in my shop to run my parts. I wouldn't even know where to start once I get the machine though...

[@DragonflyEngineering]

I don't' know of any particular books,, but I'm sure amazon has a bunch. You may want a morgen press to start depending on your numbers. If you buy a press new, usually you get a day or 2 of onsite free training and most places have a class room at their service center. Haitan or Boy will hook you up with training. For me, I started with a Morgen press, then purchased a used machine and dove in with a lot of head scratching at first.. good luck!

[@benjaminbentley6846]

There is also a variety of online training sources for beginner Injection Molding Process Technicians. Routsis and Paulson are two I know of off the top of my head if you are looking for a more in depth training.

[@thomasbraeking6225]

Best bet would be to make the acquaintance of one of us old molding technicians in your area. Injection Molding is in that fuzzy area between Art and Science. The Science tells what temps and pressures SHOULD give a decent part. The Art is where every mold/machine combination has its own quirks.

[@gokiburi-chan4255]

this is sick

[@robertbushong1751]

Is Big Yellow running in auto mode or does he have an assistant ( operator)? If so you have a lot of faith.

[@DragonflyEngineering]

She was in teach mode with my finger on the panic button! Thanks for watching

[@kichilllee]

BTW , you looks really like my daddy when his 40s~hahah , and he is also engineering burt mini injection mold .hahahaha , good job and thank you so much.

[@plasticman3952]

This machine has an auto-purge function.

[@cannon440]

Those machines look very expensive. Molding machine & robot $>100,000?

[@DragonflyEngineering]

Yes, molder new robot used. Molder is ~50K, robot was $40K. Thanks for watching!

[@greglandrum]

Is that a 22? 25?

[@DragonflyEngineering]

it is a 25 E.

[@szabifarkas1050]

hi I have a dr boy 22A and can you show me how can i take off a duze thank you in advance

[@DragonflyEngineering]

Hi Szabi, Im not sure what a duze is? Can you elaborate?

[@szabifarkas1050]

I can not unscrew the nose

[@daveeberhart2012]

Try to unscrew it hot with wd40, it may smoke

[@szabifarkas1050]

i have tried

[@daveeberhart2012]

I had to use a 1 meter handle when I did it 7 years ago

[@specialhorse8062]

Great stuff! You might want to leave screw forward in barrel at shut down. Ref ISBN 978-1466414341 page 80 #6.

[@ottoolsen9676]

imperial is not english, it is made by a swedish man, he used the metric system to make the imperial system, and the metric system was made by a french guy.

[@repalmore]

Thank you for posting this. I might be the one who is wrong but all the ahhhs are quite distracting.

[@lorabenz]

he he at 12:08 time index, its a german and its metric, Well m8 the world is metric, only 3 contrys still use the old imperial system, get metric fast m8 and be a part of the world

[@RRits57]

Worked around farms in Australia for the last 3 years, I was so annoyed because they use a combination of imperial and metric, I hate imperial, but what I hate more is working on a US machine where they used metric bolts when they replaced shit. Always have to check the tread. They even used a 3th system, forgot the name.

[@Marcothefirstman]

Macchina impostata malissimo. Faccio questo lavoro da 11 anni e lavorare in mm è davvero scomodo e poco preciso, sicuramente meglio lavorare in ccm. Stessa cosa vale per le velocità di chiusura ed apertura dello stampo, meglio lavorare in mm/s. Quando si fa il seput con dei parametri cosi approssimativi come te il processo di stampaggio è pessimo. Po lo stampo fissato in quel modo non si può vedere
