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.

[@TabletopMachineShop]

Thanks for the heads up. The surgery is a new one I guess, they said it previously couldn't be treated with lasers. Nice to know about scleral lenses, I may still have to get those

[@askquestionstrythings]

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.

[@TabletopMachineShop]

Hey thanks! I wonder why that is.... The excitement of starting before reality sets in I guess haha

[@askquestionstrythings]

@@TabletopMachineShop I blame analysis paralysis. I run out of time/stuff to finish in a day then get caught up in analyzing what to do next or how to do it. That or something else takes priority and the project gets put on hold until it becomes important enough to complete. The excitement of starting a new project is probably more powerful than the sense of accomplishment from completing a project.

[@spencerstromberg]

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

[@PowerGearPerformance]

Dont give up. Go to robotdigg.com and get a real plastic screw and barrel. High tolerance screw/ barrel fit. Plastic screw will make all of the difference in your success

[@stevesloan6775]

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

[@melgross]

I also have a problem finishing projects. A bit of ADD for both of us perhaps? So many ideas, and so little time to develop them. Not enough machinery to built them with. Sigh! So design the machinery and build them first. I get to the point that most of my time is spent designing and building machinery to build machinery... that’s in between doing it for others. I thought retirement meant I could take it easier. Never promise people who ask you to do something that; “When I’m retired...”

[@TabletopMachineShop]

Woah woah woah.... so you mean I won't even finish projects in retirement? That's when I was putting most of them off to!

[@robertomartin8731]

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

[@TabletopMachineShop]

Yeah someone else suggested that. I'll look into it. I've heard of them, hopefully they make really small ones. A band heater would take up a lot less space.

[@jeremyclimpson3129]

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)

[@preciousplasticph]

Got mine delivering tomorrow. The 2hp motor is reversable and has a fan. Will use ssr and custom g code with a 3d printer/ramps/marlin firmware to run it. Injection shot will be time based. Same as a automatic bottling machine i used last year. Unsure on the guides. Maybe 12mm rod and bearings as i.have lots on stock. Or a 16mm 12mm ball screw to.open or close the mold. Will try resin cast molds mixed with carbon fiber to increase heat transfer. The master to make the molds is resin printed.

[@deltabravo2810]

I am have the same problem, maybe I should start a business specialized in storing projects called "start and store". Btw, great work. To save on border taxes, brokar fees, duties, etc, use the country post services, like USPS, from the US, china post from ....

[@geoffcrumblin7505]

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

[@steeltree-fabricatingandcu3796]

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

[@bunnythekid]

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.

[@eatonasher3398]

You actually want the mixture to stick to the screw! It's the barrel wall that you want it to slip at. This is why you typically have to cool the screw if you're running The heaters for a long time.

[@bunnythekid]

Eaton Asher Really? That’s so counter intuitive..!

[@TabletopMachineShop]

Empty threats? You wouldn't dare! I'm going to try to polish everything up nicely so things don't stick too much -- hopefully that's enough. Coating is a bit outside my budget :P. My fastener addiction is only going to get worse. The Haas can rigid tap haha. Thanks for commenting!

[@jintat87]

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?

Hello, I really like your project. I wonder if you have drawings and materials, can you send me a message

[@titter3648]

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

[@TabletopMachineShop]

It's just the screw - it's not backdriveable, so it will at least stay nominally closed, but we'll have to see how it performs. A separate lock is a good idea.

[@titter3648]

@@TabletopMachineShop A toggle lock mechanism will increase your clamping force A LOT. While at the same time keep the travel speed up in the rest of the travel for opening the mold big enough. And you can still use the screw to drive the toggle lock mechanism. It is a simple but still very capable solution.

[@ChristopherSmith-bh4sz]

Wow, you have really over complicated injection moulding and you keep referencing 3D printing. You can do all this with limit switches and timers. For temp controll you need a PID controller(Proportional, Integral, Derivative) and water cooling for the mold.

[@TabletopMachineShop]

Yeah i guess that's the old school reliable way of doing it. Maybe I'll try to figure something like that out

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!

[@TabletopMachineShop]

Thanks! I'm a bit worried about the screw as well, but hopefully I can figure something out in the short term for the follow up video. One thing I'm considering is getting it 3D printed in metal and then just polishing it up, in which case I could definitely make the files available.

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?

[@elanman608]

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.

[@eatonasher3398]

I was going to say - I'd have no problem making this on a manual lathe. The coding might be difficult, so I second Elanman on having one of the machinists cut this on a manual lathe ^^

[@elanman608]

I do agree the easiest way is to get someone else to do it on a manual lathe but I meant to say that it is possible to define a tapered threading opperation on your machining centre I think it is G76 with parameter i to define the taper. then reduce the OD to a cylinder.

[@TabletopMachineShop]

Plot twist: I don't have a taper attachment, though the winning plan so far is to use the threading gearbox and just "wing" the taper. I think it will be okay with the right grind
