Injection Molding Machine: Part 1 

"I've got problems to finish old projects." I can feel your pain bro. 👌 really nice channel, got a new subscriber.

Any upload like this one that can make me laugh in the face of adversity gets a thumbs up 👍🏻 Please keep your videos coming. 3d printers are great, but 5 axis CNC machines and injection moulding kicks-arse!!! 👌😂🤓

Just binge watched all your videos fabulous stuff. Dont stop.

I'm glad I found this video and that I can support awesome ideas like this. Keep up the great work. Look forward to more videos on this.

Man! Your projekts are AWESOME, I think you deserve more prominence.

5:40 Nice reference to Titan. Good to see you making nice things still!

Holy crap you have all the skills. So impressive, just outstanding work.

Cool! I saw the same bench top injection molder video you saw. Was mesmerizing.

I like this project. Finish it as it would be super useful for the open source community

A captive linear stepper motor, well done :-)

Alright thank you the dog seems good after the accident, thank you for the share, remembering our first trip to have made our injection molded case for our piezo buzzer detection unit many years ago now. You get that arm better, never broke anything but hear it hurts. Lance & Patrick.

I’m surprised nobody has yet mentioned “I put a handle on it so I can take it to parties and stuff.” You are incredibly quotable, and it adds a nice touch to your very informative videos. Subscribed and waiting in anticipation...

Hey, This is a very cool project. Waiting for the next part :-)

Looks like a awesome design. I got the controller figured out... 3D printer setup Marlin and RAMPS board... with the LCD controller like 40 bucks total. I use Gcode to program it. Still unfinished as have issues with molds, and ejection pins. Also the compression molder and hydraulic log splitter injection molder have taken up time

Oh gosh, I always have a dozen projects in various completion states at any given moment in time. Nice work! I'm a nurse now but was at an engineering school research unit for many years. Vitamin D3 and Vitamin C for healing the bone and tissue trauma recovery.

Looking forward to seeing old projects finished. Thanks for sharing this one, very cool!

Rock crusher 2.0 with all the new things you've learned, yes please!

Wow youtube is hiding You very well... just found this channel and I can't believe You have only 17k subscribers. Man You deserve a looot more.

Whenever I trip and start a new project, they most definitely do not turn out as good as yours! Cheers!

I want one! Great work.

I like the HAAS "Boom" tribute to Titan Of CNC ;)

“New subscriber”😂 solely because you designed a Cast-cooler!! 😂😂😂🤓🤜🏼🤛🏼🍀🇦🇺

A ROCK SLICER !! THERES A CRAZY NEW/OLD IDEA. 50,000 AMATEUR JEWELLERS WOULD APPROVE !!

Good luck with your upcoming surgery. I've had keratoconus for going on 40 years. Not any of my business, but I was advised that laser surgery wasn't recommended since it thins out the cornea. Btw, I wear Scleral Lenses, they really have helped my keratoconus.

Thanks so much

awesome project

I worked on an injection molding machine and the plastic was melted over 4 different elements and in a longer nozzle and screw and all the elements were independently temperature controlled. It was hydraulically controlled and the molds went up and down with no guide bars in the way of operating it. On that machine was no need for a hopper but there was a motor to suck up the plastic from the bag it came in. The molds had an option for cooling going through them "just a garden hose" and you needed to use both hands to start it for safety. And the plastic was preheated in the nozzle before melting.

I'm dying for the tool tool!

You could make a melamine gasket, it’s a very bad heat conductor and rather durable :) awesome video!

LOOOVE THIS!

One thing you may want to do is make the mold holding plates similar to a fixture plate for a cnc mill one example sauders machine works fixture plates and use clamps similar to a cnc mill at my work we have injection molding machines with this kind of setup for holding the two half of the mold so all you do is lineup the injection port and clamp it down

Thanks so much brother..

About 95% of my projects are abandoned at about 90% completion lol. Looks good, I keep checking back for the update video

Looks like a proper build. I know the feeling with projects. I have two right now that are at 90% but just can't seem to make it across the finish line.

Good Stuff

Sounds about like me lol. "I tripped fell and started a new project"

Excelente,meus parabéns

Looks like a great design. Great work. I would like to know where you got the extruder from please? Is it an FDM type extruder? Thanks.

It seems that this project is almost dead after so long. The first thing you need to consider is that the entire process is a heat pump. Heat in equals heat out. Once the barrel heaters have melted the material, the dynamic action of the screw converts the mechanical energy into thermal energy. It appears that your home made screw has no compression zone at the tip. At that point, if you have insulation, the barrel heaters should by running a duty cycle around 30% with the machine cycling. You need a mould temperature controller, firstly to bring the mould up to the correct operating temperature, then to remove the process heat which will allow the moulded part to reach its safe demoulding temperature. The injection unit needs lots of power, your small parts should be filling in less than a second. Then you need to switch your filling unit to a packing phase, which will maintain a constant pressure while the moulding cools, contracts, and shrinks. I recommend the Arburg reference book as a primer, I have used that over the years teaching the subject. good luck

This is awesome! I wanted to make something like this :) Or I should say I will make something like this, just need more tools

Impressive sir

Amazing little project and very well designed too. Question, the braided cable hovering dangerously close to the SSR is insulated isn't it?

Hi, you are doing a great job man, great channel you have, very informative. actually i am a student and my project is fabrication of table top injection molding machine. Can you please tell me what kind of stepper motors (model number) did you use in this project and also any recommendation of cheaper stepper motor models that can be used for clamping and extrusion. it would be a great help

Great video! What size shot will it be capable of when completed?

3:45 most guys are *also* extractable from the rear. Nice little machine

i like this machine

Is this project still going for part 3? Looking forward for this!!!

Hello Friend! Good work, really want to collect the same! There is Part 2, etc. or am I missing something)?

I’d be keen to see how Resin 3d prints with engineering grade resins designed for injection moulding fair with this setup. 🤜🏼🤛🏼😎🍀🍀🍀

super votre videos instructive bravo

these IM machines can be a simple or as complex/fancy as you wanna make it.. Have you considered using a nozzle valve like the APSX guys? and... I don't think your baby will have too much injection pressure if it's screw-based purely...?

Good for you for the promotion,

Have you thought of using air-crete to machine your hot parts from? Looking into the thermal resistance and ease of machinability very cheap to make too.

5:38 Had me dying! Someone watches "Titans of cnc" :)

Starting projects is definitely the easiest part... now where did I leave off on those other 50 projects 🤔 Congrats on the new position, and good to hear you are on the mend after that fall.

to ptoduce a tapered thread on a manual lathe you use the taper attachment with the screw cutting gearbox to make your auger cut a tapered thread and machine off the od to a cylinder.

What about Phenolic/bakelite for the heat break gasket area? It's used for that purpose on intake manifolds in performance automotive applications to limit heat soak.

You can buy heater designed for injection molding. Search "Steel Heating Element Band Heater " on ebay.

@Tabletop Machine Shop, Are there plans available for this machine? I run a makerspace for afterschool kids and this is something they would LOVE to make and assemble!

Hi, or any of these parts and more specifically plastic feed screw is available for purchase online ?

I have also had my eye on Andrey Korotkov's machines for a diy build. It appears to inject only with the back pressure that would be produced with the screw and not have any kind of ram or ball screw for the shot. Any idea if this is the case or what would be the pitfalls of such a system?

Look forward to it being done. Will you be selling these I would need something like this.

I started building a machine like this after watching all the microplast videos. I gave up after testing my auger with a hand drill and watching the plastic just spin in circles. It didn’t really inject and certainly not with any pressure to fill a mold. I’m really curious to see if you can get plastic to squirt out the nozzle. All the rest can be figured out

Hi, I see you have some 3D models of your machine. this is exactly the sort of machine we want to build and was interested in your results, Is your machine working well have you possibly had a production run on your machine and would you be willing to share your models with us? very impressed with your work. Thanks Jeremy (South Africa)

Can you use the same motor for the extruder and the mold? ie both Nema 34 or Nema 23. Why did you use different motor? Because the design influence you took both are using same motor if I'm correct?

I've been dreaming of making one of these machines for ages, my big bottleneck is finding the right screw for the task... will you make those available when finished? or maybe you have any advice on finding them for that size? all I've ever found is for bigger machines and hate the idea of using a drill bit for that ...(auger) thanks for the nice project, I'll eagerly follow it and buy the plans if ever available!

AvE just did a cool video on a gopro spinny lens for filming under coolant.

hi was just wondering what step motors are you after using there

I'm not sure if it works for lathes too but you can "Rotary Wrap Toolpath"

What engine do you use? I'm working on this device

Nice setup! Check out mica band heaters.

good

I know a guy that worked Cincinnati millicron Building injection beer ball and bottle machines

realy its so nice boss.

plz make part 2

Curious that we share the same interests and now he have the same job. Single drive extruders can have a tendency to just spin the mixture and not extrude anything. However, they are commonly used. I imagine surface finish be key. You may need to have the screw PTFE (or something that can handle the heat better) coated so that the mix doesn’t stick to it. Also there are only four screws holding in that extruder. Either a piece of arm bone broke off and made it to your brain, or you’ve slowly come to terms with your fastener addiction... P.S finish the mini lathe or I’ll leave comments with empty threats.

Consider a stripper plate vs. Ejection pins !!

All moulding machines have the injection on the right and the clamping on the right.

hello! excellent work! can you help us to make one like it only l need the dimension of parts for this machine?, can you tell us how much it cost you to make it?... can you make a DIY? thanks for your answer! greetings from egypt

how much will it cost you to finish the machine. hope you have done it.

hello sir can we use steel barrel and screw

Yeah, I'm gunna some you a care package.

Can you get enough injection pressure using only the rotation of the screw? I think most machines use the screw for melting the plastic evenly and then the injection pressure is created by pushing the screw into the barrel.

Ха ха ха , я думал что только я начинаю проэкты и не заканчиваю их ))).

Clamping on the left

Thats cute i run 500 ton van dorns at work

Is the clamping mechanism just a screw? Or are you adding some sort of toggle lock mechanism?

The only time I had a major design revision was when I tried to make a rubegoldberg with an archamedies screw. F@(k that. Now making that type of thing is on the excuse to buy a cnc list.

any diagram to know how to built this it would be wonderfull

Hi. Good Machine . I want to do it too. Can you help me about the control unit?

awesome, I'm on the same process however I did the coding first.

It's not broken, it's just "resting"

Or if you have a drawings? What is the cost of them?

Nice project indeed. Any option to make it an open source project?!

I have a question I want to model on of these for fun, going into mechanical Engineering, and I'm wondering what flange bearing that us you're using for the screw. It looks custom but I wanted to ask if it was pre-made. I like the idea and design on would be interesting.

Each brand of lathe has it's own way of syncing spindle rotation with live tools. Forget about threading operations to program that, it will never work. It can be programmed as a milled feature on the lathe or on a mill with a 4th axis rotary indexer. If your guys are new at programming live tooling on the lathe the may have an easier time programming it on a mill.
