Thank you for your time and shared your knowledge...I am about to build a desktop microinjection machine with 2 pneumatic cylinders (one for injection, the other for closing the mold) and I ran into a couple of problems in my original design, such as the high cost of making many parts by laser cutting. The use of the 2020 profile largely solves this problem, and reduces the weight of the machine. As allways, your videos are pure gold... Regards from Argentina Responder

Would there be an easy way to extend this to 6in3? I'm working on a design for a non-profit, but it's too large for this. Would it be possible to make two of these and operate them simultaneously in one large mold to extend the max volume to 6 cubic inches?

How does your production time compare with 3D printing? Also is it possible to make items hollow?

@robertmartin2936

2 жыл бұрын

it's really night and day. 3D printers may allow for larger total objects depending on print bed, where injection is limited in size by shot size and mold dimensions, but what would take hours to print really takes maybe less than a minute to inject. So if you need quantity of any part, there's just no contest. Regarding hollow parts - the injector is going to solid fill any void the material is injected into. So there is no physical way to do something like 40% fill as you might in 3D prints. Injected material has more stability than printed material though, because of how the molecular structures are formed, so even in the same material (ABS for instance) an injected part will have no delamination or material layer failure as printed material may. If you need something hollow, the only way to achieve that in injection is to make a pair of mated parts and bond them together after injection, like plastic Easter Eggs.

What resin are you using for your molds? I asume some high temperature resin. Did you try normal 3d Printer resin? If so, how many shots did normal resin last?

Hello. I honestly wouldn't go wider then the chamber already is. You really need to go longer otherwise you will start to get colder plastic in the center and hotter plastic on the outside.

@BusterBeagle3D

Жыл бұрын

If the mold is nice and tight, minus the air vents of course, the mold should fill with the plastic and then you need to hold the pressure to prevent shrinking. Once you let go the pressure releases and the chamber retracts. Whatever plastic is left in the chamber is set for the next shot. All of this is to say that yes you should be able to inject in any mold 3 cubic inches or less.
