DIY Injection moulding by JR Hartley.

Now there's a subject close to my heart :rofl:
Here's a useful link...

I started making an injection moulder because I didn't have room for the real thing in the garage. Then I suddenly got space and bought an old 25 ton Arburg, haven't plumbed it in to the 3 phase yet.
The point being, I have most of a home brew, fully automatic injection moulder about 6 feet behind me. All hydraulic, opens closes, ejects, injects from a hot pot a la Travin, measures plastic in, heaters all wired up with a digital thermostat, plugs in to a paralell port for all the critical timings etc.
I don't really want to sell it, but I can be arsed to finish it. If you are interested I am sure we can come to some arrangement :naughty:

Thanks for the mould mft link - Have you had a quote from them for a mould?
Your injection mould - being 3 phase would be a problem (I'm low-fi here!)...I'm also envisagening an unfeasibly large contraption!?

I think your main issue might be making the mould. There are only two moulds for the one at school - both made by the teacher. He told me they were difficult and took a long time to make, especially since he used the surface grinder on the mating faces of the two parts. I guess it could be easier to CNC mill the mould, but still something to consider.

I guess most people aspire to a nicely finished mould (so no machine marks are visible on the end result) - but since these puppies will not be visible, I could probably accept a rough & ready one! I'm hearing that Aluminium loaded expoxy might be the route for the mould for my modest requirements.

R.E. Bobbin making.
Couldn't you just cut them out of a sheet and use a T-slot cutter to do the undercutting? That way you could machine the lot in one go.....and tessellate lots onto a sheet of plastic

That's a reasonable idea...I might ponder. It'd certainly make the beard a little bit shorter (more Rolf Harris than ZZ Top), but I'd still prefer unshaven (I'm talking beards here - right?). Also, a quick skeg on the net shows they might be a bit hard to find? (ok, so Argios probably isn't the best! -joke ok!). BTW that second link - he rocks, talk about understated....legend!

Which Commercial road ?.

C'mon, You know the one (psst: you never heard of tipping?)



PS Not related to injection moulding at all, *but* hot off the press tonight - another 'machine for the home', after much trashing of plastic & flaying of switches & sensors - a 'direct to copper clad board' inkjet printer :-)



Edit: Just seen your post...

funny you should mention a desktop stand alone plastic injection machine, i have the very same thing.

We need more details than that - a photo to prove it along with a scan of your driving license etc. Seriously...I need more details - I think I now need the opposite to viagra (flacidagra?)
