good job with what you are making from the waste I assume you are using acetone or similar.
My plan is to rather than make stuff with the waste to sell or give it back to the eps manufactures as it can be recycled back into new eps or other plastic products so I’m trying to keep it relatively pure.
I have made some progress and now…[Read more]
Just wondering if anyone could help me with learning how to draw a helix screw with a changing pitch in fusion. I know how to import a csv file but as for the maths to calculate its straight over my head.
I had a go at putting the screw on the lathe and surprisingly it worked quite well and I have been able to turn it down so now although smaller I should be able to get it to fit a tube once I can fine a nice seamless bit.
at the moment im thinking along the lines of maybe a two stage machine the first heater to de bulk and then a second to do the…[Read more]
I think the best thing for the auger is to try and put it on a lathe to reduce the diameter to fit a tube( would need to get it down to 73mm I think which isn’t a huge loss. to do so on my lath I would probably have to reduce the length a little too still probably ok for testing.
Im not sure if its going to be better to head the polystyrene when…[Read more]
Hi thanks for the reply I have spent a long time searching for a diy solutions but not found anything that has beet taken all the way to a working machine. I had not thought about heated rollers my fear is it would stick to them so I guess you would need something to scrape it it off.
I had noticed some screw use the same pitch with a varied…[Read more]
Currently are local area does not have any way of recycling polystyrene however it is possible to get it recycled by a number of companies. The Problem with polystyrene or eps is it is over 80% air so storage and transporting it in standard expanded form is not cost or environmentally effective so it has to be compacted to do so. The best for of…[Read more]
