Zelenew Basket Extrusion (V4)

Hi guys

I’m Istvan, one of the helpers in the V4 team currently working with food, waste management and administrative taskts. But in my spare time i’m also here to learn the craft.
During Dutch design week this year we had the chance to meet talented creators from our community like Diti @Thela design, Aniol /Mark @talleresferica doing sunglasses, Jivan from Zelenew @greendaddy Ukraine making baskets and so on.

During his stay with us, Jivan made a presentation for us with his technique on how to make beautiful baskets and i feel that it’s important to share this with you guys on the forums.

Key things to remeber in your attempt to replicate his process:

¤  Use HDPE only
¤  Use a custom nozzle. the idea is that you drill a small hole through a standard star head screw and insert that into your big nozzle. ( remember to tighten these parts very firmly together, otherwise due to pressure the nozzle can fly out with high velocity and hurt you). The picture below is only to give and idea.
¤ Wrap cotton textile around your mold as shown in the video, this helps the plastic to stay in place and makes the handling easier.
¤ Try to make the process as streamlined as possible, that way you can stay seated and keep working, using a mirror above the plastic holder, long pipe,  a pedal for speed regulation and temp. controllers in reach close to the nozzle, are all things that Jivan from Zelenew is using to create the baskets we all see on the Bazar.

In the video below you can see his process from start to finish, big thanks to Jivan for letting us share this info with you guys

To sum it all up: good luck in replicating the process,I believe what Jivan is doing is handcraft, might seem easy to replicate but in reality it’s a lot harder than it looks like. If you do take on the challenge please share your results with us in the forums. Questions are more than welcome.

Amazing! Thanks for posting! The cotton cloth over the mold makes a lot of sense – I’ve been having trouble doing baskets like that with just a regular stainless steel bowl.

Amazing it is!
We are facing a problem using the cloth for the pattern basket i.e. its is quite hard to separate the plastic from the cloth after it has cooled down. It also leaves fabric fibers stuck to inner surface of the product. This is happening with both with HDPE and PP. Temperature used of HDPE is 203 – 212 Farenhite and for PP it is 221 – 230.

Hey @samsara

Those temp should be fine.. Don’t think the problem lies there. We set our machine to run at 220 C for HDPE and 200 C for PP.
Perhaps try using a different cloth? We use something with quite a fine weave

we use paper for the mold

This is awesome, I was wondering how those baskets were made. Thanks for sharing this information, it helps a lot to understand the process.

Time to build an extruder and start experimenting 🙂

Keep up the great work, Nike
