I would live a follow-up video of you making more complex parts so we can see the limits of the machine. Things like thin walls, larger dimension pieces, complex geometry parts.

Can't wait to see more videos on this!

[@cannaroe1213]

I think a lot of cable connectors are molded around the cable itself, i.e. they don't come off or have any pretense of reuse. Also a lot of them are coming out of patent, and I can see mechanics buying a set of molds for their particular car brand. A pipe joint or some other waterproof tube would also be great, a lot of applications there. At some point it's your ability to make high-tech molds that becomes the limiting factor, not the hot glue gun.

Nice work! I started a molder like this but burned out when I got to making the chamber/nozzle. Just ordered your parts to finish it up.

[@BusterBeagle3D]

I got your order and it will go out first thing in the morning! I do agree that the chamber was the hardest part. I went through many, MANY, iterations of it. I even started by trying to make it solely out of available parts and cobbling it together but that never worked. I went through about 8 manufactured design prototypes before it was dialed in. I would love to see your version once you done with it. Thanks again.

[@dl08in]

This is a very nice build. I may just need to attempt this myself. One thing I would caution you on is the solder type heat shrink connectors are not a great choice for this application. The connections to the heater elements in particular should be mechanical connectors of some sort - preferably heat resistant. Solder is fine for low temperature, low current applications, but it could melt from the higher current and temperature it is exposed to here.

[@Graham_Wideman]

And the type of wire connecting to heating elements is often a type that doesn't accept solder. Note that most similar heaters on eBay or Amazon come with screw-clamp connectors or other mechanically fastened connectors.

[@theotherebikeguy1473]

Good point. In fact the low melt solder has to be a bismuth tin mix.

[@ericennenga7218]

Excellent video, clean build. Love the concept of using off the shelf components for the build. If I were to build one in would be with the intention of molding disc golf discs. This would require a larger volume of plastic. Not sure off the top of my head how much more.. best guess is triple the volume. Ideas? Thanks for the great content! Keep it up!

[@BusterBeagle3D]

Thank you! I'll keep trying to put out content as much as time allows me to ;) Yeah right now this machine is really limited to parts smaller then the golf discs. I guess the concept could work the same way if you design a longer chamber with more heaters and a larger frame. It's definitely something I will look into depending on the interest I get in the machine. Thanks again!

[@jttech44]

larger parts will require a larger chamber size, and it will require more injection pressure and mold clamping pressure. Something like this baby machine is fine with just a couple C clamps and a drill press, but you may need to go to something based around a vice and an arbor press to cope with the forces involved. Also, if you're planning to do any sort of volume, you will want to find a place local to you that can build you a mold out of steel. Steel is more dimensionally stable with temperature, and it will allow for the clamping pressures that you need. In addition to that, while you're having a mold built, you should also consider incorporating some cooling channels in your mold halves so that you can quickly cool parts and maintain some sort of stable mold temperature. Once you're done with all that, you'll have most of the features that a commercial machine would have.

Would be nice to recicle plastics like PET bottles for instance..

[@anthonybevers6066]

Have you learned anything more about PET plastic recycling? I have seen where people have made small scale bottle shredders and the plastic is turned into fine shards. The melting point for PET is 270-280 C so i wonder if it is possible to upgrade the controller to melt at higher temps if it doesn't already? If possible, there is a lot of material just laying around outside (unfortunately) that can possibly be repurposed at home.

[@Spartacusse]

@@anthonybevers6066 PET loses some of it's properties when re-melted, it probably can't be used for the same purpose, like a soda bottle, but nothing stops it from doing an other function, a more thick part, like an end cap, handle or something. If this guy kzbin.info/www/bejne/gmS3qXaAgMeAe7s can simply cut a thin strip and put it thought a slightly modified 3d printer, I don't see why one couldn't push into a mold, since 3d printing needs a much more precise and consistent feeding and injection is much more brute force and forgiving.

[@elementiro]

@@Spartacusse well, honestly all plastics lose properties, maybe just one more so than the others. That should be fine if you consider that in your process/design and if you're fine with it for your item. Industrially, from what I've heard to maintain high quality no more than 5% of input should be recycled material (usually coming from the factory itself, for example from cutted off extruded pathways in multi-item moulds).

This is incredible!

[@BusterBeagle3D]

I don't believe it is possible to inject twice into a mold with any type of machine. You can inject twice if you are over molding a current piece but not if you are just trying to fill the same cavity.

[@sspence65]

being a coated metal, I seriously doubt that ground is actually grounding. drill a threaded hole into the case, and use a ground bolt.

[@danielbecker8373]

Also since plastic is in the stack, the ground can loosen with creep.

[@michaelschmidt7014]

Also in any manufactured machine NEMA Code requires a separate ground point. This ground point does not perform any other mechanical function(s) as they can loosen thus loosing ground. A drilled and tapped hole for a screw or a self-tapping screw could be used. Further I would use an eyelet terminal so that in the even the screw loosens the ground wire will not fall off. A second ground wire needs to be run to the lower bracket holding the injection nozzle and heater assembly with the same installation of the ground as the upper assembly. Great video.

[@David-sp7gc]

Need to scrape the paint off the heater bore and behind the nut. This not a very good ground path as shown

[@RV6Tweety]

Came to the comments to say this as well. That ground connection needs a star washer to bite into the powder-coated case, the spade terminal should be a ring terminal so it can't be pulled out accidentally, and it should be properly sized for the bolt it's going on. Also worth pointing out that when you reverse the forked terminals so they don't scrape on the case, you're also defeating the purpose of a forked terminal, which is that it can be inserted without removing the screw. Might as well use ring terminals all around and be completely secure.

Between your videos, Crafsman, and JohnSL, we're really spoiled for injection molding content right now. I appreciate the amount of attention given to the PID temperature controller setup; I have an Emco 999 benchtop machine that I've been wanting to modify with digital controls and it shouldn't be too difficult to adapt this arrangement to my machine.

Glad I could be of some service. Thanks for watching!

Fikir çok güzel. Kalıbın daha kolay sıkıştırılması ve daha düzenli bir hale getirilmesi ile çok daha profesyonel ve hızlı bir makine elde edilebilir. Elinize, emeğinize sağlık.

Great ideas. The problem is, how to get these moulds? Machine them?

You're a genius! Just what I needed. Thank you so much, all the best.
