- Hi Folks,
This week we load and run the white ABS ring molds that we have been making over the last few Episodes..
Also, we use the "Sprue Wacker" on this mold; you can see how it was made in this episode:
• SPRUE WACKER for plast...
Enjoy! - Věda a technologie
Great job and I literally laughed my butt off with the Christmas Story bit! I'm a 60 year old mold setter and I cuss at every change over.
Thanks for watching! I think I am running those same parts now!
Thank you for the well-executed trials to ensure the product comes out well
Shakespeare 😏the wacking of the sprew.😅
DME makes a pneumatic coupler for center knock outs. they are a bit pricey but it will save you lots of swearing. also bump the nozzle back and forth a couple times to get the stuck sprue loose.
Thanks for the tips I will try them out.
Very cool- that's gotta be one expensive piece of equipment!
I don't know why it is so fun to watch someone else work their butt off . Have a Joyous New Year!
Every video you make is a master class! Thanks for taking the time to bring us along.
Thanks for watching Greg!
No they are a joke
Beings back memories 30. Years in plastic molding good fun
Great video, I have done blow moulding for 42 years so very informative, thanks for sharing.
Can I ask u some questions
yes of course.@@chaibamin1335
I have never seen such a machine before, and I feel amazed by seeing it. Before this, I had only seen a machine with one injections unit...😮😮😮
Do I work we have one that does three shots
Where
I work we have a 3 shot
Good work!
I recommend visiting a plastic injection molding company and observ a quick and safe tool change. It will definitely make your work easier and faster.
But, job well done.
Wow that is a monster size machine!
Thanks! My wife got it for me!
@@DragonflyEngineering Does she have a sister? I could use a 40 ton machine.
👍🏻Отличная работа. Я сам занимаюсь литьём пластика уже 12 лет. ХАЙТЬЯН отличная машин! У меня сейчас КАЙ МИНГ.
That is a clever trick with the integrated tunnel gate cutting. 👍. Would a tapered hole for the tunnel gate help reduce the chance of the center stem getting stuck?
Thanks, the center runner hole is tapered, but sometime a rivet head of plastic on the nozzle side causes it to be stuck. Thanks for watching
why screwing back was slow back pressure. enjoying this
Pretty cool video. Custom sprue Wacker lol
Nice work😊
Thanks for watching
I noticed you said you don't really have to run water through the molds.. does this cause zebra striping for you or ghalling of the tool? Having them watered can help you choose where you want the parts to stay as well and help with the flow of the plastic and the cooling process to be shorter. What do I know, I'm just a mold setter.
That is true for Aluminum molds, that conduct heat 4 time better then steel. For steel molds, I do run water, or oil to remove hot spots in cores, and heat the mold up. Haven't had much problem with zebra striping. Thanks for watching!
Good videos . I was a Machine setter before, and I do have some comments and points to add.
1.) I suggest you add a leveling tool to ensure the mold is properly leveled before closing the mold. because you might close it unlevelled.
2.) I Don't remove the chain block support even though you have fully clamped on the fixed side. There are times that a mold setter have not fully tightened the brackets on one side and the mold droops or worst fall. I removed it when both A&B sides are bolted on the platen. If one of the A/B loose support or fall from plates, it will hang to the other half.
3.) Remember to put hard hats when moving molds overhead. sometimes eyebolts clips breakout or not fully locked.
look small presses 1000 ton n below /// I watched and do right now //// just screw the FucTYg rods into mold use crane ///shutmoldinsetup
Thanks for watching, and thanks for the tips!
You are very professional
Pero el molde ya tendria que tener las placas aislantes incorporadas
Can you share the equipment you use?thank you🙏🏾
Using this ejector extension rod means rotational table cant rotate right?
Sprue stuck you might be can reduce gate seal time or make undercut pin to pullout runner
Yes, that is correct, 2 shot molds need a spring ejector return
What are the equations used in machine settings?
Not much practical equation use, it is all experience in my case. Thanks for watching
👍
Why not use a locking coupler on ejector rod?
i am a tool setter, why not open the plattens, then eject slowly then connect the coupling
I think because the toggle clamp arms (in open possition) wont let me get my hands in there. Thanks for watching!
nice Mr
Thanks for watching!
How much does the plastic cost per part?
How much does each part sell for?
Sorry, cant get into sales price since it is for a customer. The plastic cost about 0.90 since i buy lower quantities
Can you share a link for the McMaster material you used?
Yes, once I get to a computer, I usually buy from aqmolds.com
It's doable unit
Amazing work as always served part of my Apprenticeship in the mold shop here in the uk…you need a bigger shop looks like a right nightmare chaining loading and clamping…not easy for 1 man with a manual crane as well…respect
Thanks for watching and the nice feedback, one day I will move to a bigger place
Bro look like Spider man, Peter Parker 👍👍👍
how did you center the tool? i didnt see a centering ring
check out 4:55 - 5:10. Thanks for watching!
Can I ask u
no cooling ? is the nozzle tip the right size? sorry ill shhhhh
yes, for these parts aluminum molds sink off enough heat
You take off the strap and crane before u close B half of mold....i make sure all 4 bolts are in bedore i take crane away just a safety with me but to each it own...also u dont use a level as well..
Please add polish subtitles :)
Why wouldn’t you just bolt the insulator plates to the mold. I would be afraid that that ejector rod would snap when running. Then finally why wouldn’t you torque those toe clamps in.
I have some that are oversized insultators to bolt to the molding machine, but I have so many variations of molds, that I usually block mounting holes, or need the ones that bolt the insulator, so I keep them simple. I save $ by not making insulators for all the molds. I also have universal shim plates to get the 2 mold stacks the same height. Yes, as i mentioned I get away with the 1/2 inch rod for light force eject molds. I have 1.5" dia ejector rods that came with the machine too. finally, i don't have a torque wrench :( But I should get one. Thanks for watching!
setup molds
Waooo my dream job
Can I please join you
I'm spart
we are mold maker in Shenzhen China, please contact us if need make plastic injection molds.
Take the carriage back before trying to remove a sprue
So much I've seen wrong, can't watch anymore! you sir be safe, and you need to clean your shop. I have fired employees for leaving less of a mess! And for gods sake, get a safety panel over that control panel with all the exposed wires!
Could you kindly direct us to your channel so that we might be more fully enlighted as how to do things properly.
WHAT Really I'm a PROCESS TECH , You sir are a beginner at best like the vid you should see the real world
Thanks for watching!
Glad i am not the only one that thinks this! Process Engineer here, with 20+ years in Plastics.
Nice shop, nice equipment, however the most backward thinking on molding I have ever heard. 40+ years in the business and never heard so much crap that I have heard on your channel.
