For our prototyping so far, we used a 10t manual hydraulic press that cost us around 200€ in the beginning of V4. It enabled us to try out all kinds of things and  to make the first bowls and containers from our biodegradable materials. Moreover we moved some things around, added first portioning prototypes and upgraded it with a pneumatic motor, so we can use our air compressor to do the pressing. This automation was important to me, since I think it's helpful when you are pressing a new thing every two minutes. Since we now felt like we came to the end of that prototype and that it was time to start the actual building of a press from scratch, I came up with a few concepts. I think the easiest thing is to just go through it and explain my thoughts and then you can commment, if you have better ideas: In the beginning I really wanted to go for a C-frame press, since I like how easily accessible it is from the front, but after running some force simulations on fusion I  realized how thick everything has to be to actually take the force of 10 tons. So I decided that it would be a liiiittle too heavy and look too scary looking for our purpose👻 So now the prototype I am going to build next is a simple build from threaded rod, steel profiles, which already a few DIY people out there made. Moreover I ordered a hydraulic jack with a pneumatic motor to take care of the automated pressing. (https://www.ebay.de/itm/Stempelwagenheber-hydraulisch-Stempelheber-Pneumatischer-Wagenheber-18000kg-18t/163639580393?hash=item2619add6e9:g:yuQAAOSw5gZcqwKq) The threaded rod will be M20 and two on each side should be enough to take the force even at an angle. Additionally it's cool, because it doesn't require any welding, which might make it more accessible to some people. You can see a screenshot of the CAD in the images. I will keep you updated on the building. 👨‍🔧 Let me know what you think so far!
