PotClau, a new product to inject
From Taller Esfèrica we wanted to share our new product that can be built with the injection machine. It is pot-keychain where you can keep small things that might get lost.
We needed a small product that lots of people in a festival, event or workshop, could inject easily using the plastic waste generated in the event and take it home. That is why we designed this product.
The cap we use to close the pot is an existing one from milk or juices. There is no need to make a new mold for a new cap when there are plenty in our surroundings :). This way, our product has a bit of reuse and a bit of recycle!
The walls of the pot are 2mm thick. We made the leaver longer and reinforced the machine and we have managed to inject the pot with PP and LDHP because of its high melting flow rate.

wow that looks REALLY good! Love to see you guys are continuing and focussing on what to make with the machine. Nice detail to use the cap 🙂
How did you make the mold, CNC?
Yes, the mold was made using a cnc machine. We are now looking into alternatives to be able to have super cheap, easily recyclable molds, but it isn’t easy.
In the long run we are aiming at creating a service for waste management where inhabitants of a neighborhood are mico waste managers, dealing with certain elements of their home plastic waste, by bringing them into the facility where they can transform it into a shiny new product. This way, we will be creating smaller waste management loops, not relying on huge waste management systems that deal with far too much material to be able to do it properly. Imagine every neighborhood in every city having a facility like this…over the time this service could have a big impact, avoiding burning or burying plastics, and educating. And not just for plastic but for other materials too, with time. Would that make sense? Energetically, economically and socially? Well, we are looking into it!
Really amazing guys..
Thanks for feeding back your knowledge to the community.
We’re ourselves working on making it easier to create moulds and products with the machines.
Would have some pics of the mould?
Would you be up for sharing the file too so more members from the community could benefit from your great R&D?
Keep it up!
Here I attach you the technical drawings and STEP files of the mold we designed. As you can see, the dimensions are not round numbers. This is because we scaled the mold up to avoid contractions in the final pieces when the plastic cools (it needed to fit perfectly with the reused cap).
The mold seals hermetically with the nozzle of our machine with a conic shape.
By the way, the cap we use is standard in Spain, but we don’t know if exists in other countries. It would be nice to know!
I hope you find this information helpful, and if you need anything else let us know!
That’s nice work! Did you have to heat the mould to inject it successfully, or were you able to do it cold?
It works fine without heating the mould, but after having injected a few, the moluld gets very hot for being in contact with the hot plastic and the nozzle. Then it works even better.
That’s excellent work, and a really neat product. Interesting to see your mould too, thanks for sharing!
thanks for sharing those files here. Your mould is just awesome, i’m jealous!
Nice! We really like this! How can we get our hands on a few of these? We can’t describe how inspiring this is using words, unfortunately, but lets say we really really like this 😀 Some day we will be making stuff like this ourselves, but until then we just want to support everyone who already does. Please get in touch, and thanks for sharing!

¡Gracias por compartir!
really cool! congrats 😀
Creative, functional, beautiful, clip-, ring- or lanyard-adaptable, … awesome work! With that capping system, are they waterproof, too? I bet they float. I can think of a hundred things I would put in this, and similar containers of varying sizes, for camping, hiking, picnicking, trips with kids, trips WITHOUT the kids… hm… two thumbs up and a high five!!
I’m having trouble figuring out how it becomes a canister. I can’t open the .rar file on mobile. Apologies if it shows more detail that I can’t see. Is there any other info you can offer for recreating? PDF works, not sure if you can transfer the file over.
I see now. I had assumed the threaded part screwed onto the injector and the hole at the top was for air escape. Decently expandable into larger units, once the mold is made your all set. 🙂
