Machine Inputs and Outputs

Can anyone that’s built their own machines or is familiar with them give me some numbers on how much line you can extrude with the extruder per hour or day. How much you can shred, how many moulds you could inject etc. And possibly how much power it takes to run some of them? Thank you  🙂

hi,you could try search function of the forum. It’s all there: tables, times, etc.. it’s hard to find these things back here, good luck.

extrusion  motor output runs  with 30 – 50 RPMS, at around 300  – 1500 Watt, depending on the screw type (beams need more power). you could convert this to feed per minute. in top it wants around 800 Watt for the heat bands…

shredder wants at least 2.2 Kw, 3Phase, about 50 – 70 RPM around 6-8 amps for average plastic, 3-4KW for heavy stuff. It’s tedious work with the PP shredder, please consider buying a ‘plastic granulator’ from aliexpress or ebay.

turn-around time for injection depends on your clamping and cooling system but count on 10 – 30 minutes per object.

sorry, but the PP owner doesn’t want to update the site’s content with these numbers

so that makes near 4Kw per hour. according to green house calculator, this is the equivalent of driving an average car for 7 miles long to make your precious object 🙂
