I knew a guy years ago who had a virtual monopoly on the industry of manufacturing small plastic shims for cabinet hinges. They did all the injection molding in his father's home shop. The trick was that the mold itself was preheated to somewhere between room temp and the transition temperature of the plastic. This meant the plastic cooled less as it was being injected and they could make more parts at a time.

A friend to the family was a tool maker, and that included making molds for injection molding. My father helped him a summer when he got to much work. He kept making the molds while my father got the grunt work of polishing the molds which was necessary to make them release easily. He got a completely new appreciation for the amount of work it took to make a good injection mold.

Yes tooling for injection molding can sometimes even cost more than the machine itself. The molds we use in the place I work now typically cost about 35 to 60 thousand USD. The first plant I worked at had the most expensive tooling I've set at 450 thousand for a mold that made two 5 gal buckets every 40 seconds. You can find those buckets on the shelves at Walmart.

Nice Video. As an experienced injection molding machine engineer, the normal position for the thermocouple is between the heater bands. The position of the heater bands is also important. The heaters should be close to the nozzle. Because the heat will be highest at nozzle end of the barrel and radiate to the material feeding point. Which gives the normal temperature profile found on conventional plastic injection molding machines. Hope this helps guys.

Subscribed. Injection molding technology is one of the most expensive and prohibitive for an average joe. Even if the part cost is really cheap - no commercial company will honor an order smaller than a few thousand pieces, and the cost of the actual mold is immense. Thanks. This would close a GAP in he dyi community - since most of us have small batches of products and either we are forced to use "off the shelf" cases and design our pcb's around those, either use not so "professional" looking 3d printed cases (wich / gram are MORE expensive than molded ones). Really thanks. The ideea floats around on the web for years now - but i've seen few or none actuqlly viable working projects.

It doesn't get very expensive in the long run. The very manner, construction and function of this limb amputation machine saves the user from all too many expenses in the future (and from a too long life too...). I suggest getting ideas from their other machine ( Homemade Plastic Injection Machine | DIY, kzbin.info/www/bejne/omXKeIqrm9R8j6s), add proper safety enclosures, an appropriate user interface for this kind of machinery and required devices like safety relays and emergency shut down. Just to keep the prosecutor away ... ;)

Just some cents to ""off the shelf". You mean those enclosures who come in a million different sizes, shapes and configurations, rev3rse[2]? Those which are produced by experts? I mean, you can ignore that material testing equipment and quality testing exists (like all of you guys do ... like that is an option!!!), which the machinery costs usually are 10 times[1] that of the production machines, not speaking of the expertise needed ... and have that reflected in your products: Unreliable or even with a risk of injury and with inconsistent properties. That kind of attributes does not necessarily increase trust in small manufacturers and DIY products. Occupational safety standards and quality standards, material and product testing should not be seen as enemies. On the contrary, they are important achievements of modernity, without which we would be worse off! [1] This is the place where people look in disbelief. But that is due to the lack of a clue with industry practices and requirements and that one prefers ignorance to responsibility. This is a widespread disease in maker circles and another reason for the proverbial amateurish poor quality. [2] And which also can be ordered as self-designed and produced as prototypes or in small series ... and we think we can do this at home with the same quality and reject? No!:)

This is a really nice machine for small runs or testing molds. I'd like to suggest two changes: 1) Attach a second ground wire to the heated tube as this only has minimal surface area connecting it to the rest of the chassis and the band heaters are mounted to it. 2) Connect an adjustable timer module to the switch for the hardening time so that it can be set and consistently repeated. 3) For the mold, you might be able to add a couple of extra ejection pins which push directly on the other half of the mold and a bolt to pull the ejection pins into the mold, so that you can release the two mold halves and the part in one motion by tightening that bolt. That would remove the need for the screwdrivers / screwdriver slots and the the hammering. Bonus points if you can use a small pneumatic cylinder mounted directly to the mold to actuate the ejection pins instead.

To improve the design you could do the following: 1) Take care of tube length from pressure origin to delivery point to be exactly the same, air volume is critical in pressure delivery. 2) Drill two holes in the lower, middle front and back plate to press through a hardened steel pin to support the lower part of the cylinder.

I like the concept (I'm in the Precious Plastic Community, Precious Plastic Romagna workspace) but I think there's something wrong with the design. Having the cylinders on the sides saves space for sure, but you can't have their full force, since they're working with the lower area side of the pistons. The top plate is also bending during injection, and before the injection piston enters the chamber it moves to the side, since the two pneumatic cylinders don't move at the same speed. Better to prolong the injector barrel to guide the piston, and insert the material from a lateral hole in it, or add a plate to guide it on top of the barrel. And also add reinforcement to the top plate, when it bends it forces the rods to the inside.

To increase injection pressure, you could change the design for the action of the pistons. Instead of contraction to inject, extend to inject. The amount of force is reduced on the piston head because of the rod. If the piston chamber is 2" in diameter, that gives a volume of 12.56sqin. At 120psi, that would be 1507 lbs (6703N) of force. Because there is a rod on the retraction side, and it's about 1" round, this cuts the force down in half. Which you mention as 3300N (741lbs) of force. So just by changing the design to extension to do the injection, you can still use the same size cylinders, and you'd get twice the force. This would keep the cost of the design down, and yield a more powerful unit. Another thing I would do is make the injection rod have a taper for going into the hopper. This would minimize any introduction of air that might get trapped on the end as it's plunged down into the plastic. It would allow for more precise auto-alignment.
@ActionBOX
@ActionBOX 2 жыл бұрын
Hey, thanks for the detailed comment. This has been considered, and the issue with the extension is that while it provides a little more force, it would require me to flip the cylinders around, which would make the machine 50% taller. I was looking to make the smallest possible form factor. As per the injection rod, it has a slight taper, but perhaps more will indeed help. Cheers.

@korishan 2 жыл бұрын
@@ActionBOX Yeah, flipping it over was the part I was tryin to figure out how to get around. Maybe there could be different versions available. Some ppl may not mind having a unit that is twice as tall. Me personally I have plenty of space for such a device. But I also get the reason for needing to keep it compact, as well. Great idea overall, though. I had been wondering about injection molding and how to go about it. This seems about as simple as you could get, to be honest. Job well done guys! 😎

I suggest the thermocouples placed at the very top of cylinder, right below the holding funnel that is still made of metal, since heat does not transfer quickly, even if the bottom plastic is already a liquid, there's no guarantee that plastic at top is also liquid, so make sure that the top get the proper heat for liquid plastic, before injecting the whole cylinder to the mold

thanks for your comment. We actually intentionally left the top cooler so the plastic does not melt there. Otherwise if it melts and gets sticky it makes it very hard to load new pellets. Cheers.

Fantastic design! Great job! From the CAD model it looked like the nozzle is chamfered, you will get better contact with a radius instead. The mold needs to be machined with a matching radius, it doesn't need to be a small radius, either. You want the most surface area possible.

KZbin suggested another video of yours and now I'm here as a new subscriber. Awesome videos and like how you get straight to the points with explanations. I'm a noob with injection molding so how do you prevent too much plastic from being injected into the mold? Example is if you had a smaller volume mold with the V1 injector?
@ActionBOX
@ActionBOX 2 жыл бұрын
Thanks, that’s means a lot 😊. With this machine it just fills the mold until no more goes in, but the pressure stays. In other words, your mold needs to be closed very tight so plastic doesn’t leak from the sides. The machine will then naturally stop by the fact that the back pressure is just too high. Does that answer your question?

How about heated and cooled moulds? Add heaters to make the moulds hot, but just under the melting point of the plastic. Then, add water channels through the mould controlled by another solenoid valve. with the melt chamber and mould at temp, the inject button works as usual, with the heated mould acting to promote complete filling of even larger moulds. On release, the water cooling solenoid opens to quench the mould, draining into a sink drain or similar. Once the mould thermocouple indicates that the part should be sufficiently set, that releases the pneumatic solenoid to withdraw the ram. with a mould designed to open easily, another pneumatic ram could actuate the ejection rams, automaticly ejecting the new part. Adding fully automated closing, dogging, undogging, and openning of the mould itself, as well as an automaticly feeding hopper, and you have a turn-key solution to injection moulding parts on a (light) industrial scale.

It's cool that it worked with a aluminium injection barrel. I was considering making an injection machine and thought i needed to make the barrel out of stainless steel for it not to wear out. But you should do something about the air cylinders not moving at the same speed making the plunger tilt. This can also cause the cylinders to bind.
@ActionBOX

Thanks for your input. The cylinders use to have the tilting and binding problem but not anymore. We hold the plunger shaft loose so it can guide itself into the hole and that seems to work well.

Nice and simple! You might just want to turn the pneumatic cylinders upside down on your v2 so you get the maximum force out of them. You're currently pressurising the rod end side, so piston area is reduced; I think the cylinders won't develop maximum output force this way. Also watch out for using the blue polyurethane airlines near a heat source, you might consider using PTFE tube inside the frame.
