request for beams

04/12/2017 at 16:14

I’m building the shredder and the extrusion machine, and I expect/ hope to finish the building at the end of this year.

I got a request to make approximately 200 plastic beams from recycled plastic, and I would really like to accept this request but I’m not sure if it’s even possible/manageable. So my question is if anyone knows how long it takes to make one beam with these dimensions 900-200-30mm. (5,4 liter)

with other words what is the maximum output from the extrusion in liter/minute
(the liter in this maximum output must preferably be measured when compressed)

thanks in advance,

What are the beams to be used for? Are they structural? Be aware that they will not have the same physical properties as say, wood, so if you plan to use these in the same way you may have to make changes to the dimensions/design.

Yess they will be used in a strucural way but they’ll have plenty of support so that’s not an issue. (I might make some adjustments in the dimensions after I have my first one depends on how they feel and act)

they will be placed side by side in length like a floor and supported by cross beams from probably wood depends on how strong the plastic beams can be.

I’m planning on doing a thorough test of the beams toughness anyway (if that’s the correct word) to really test their limits. In this way I want to look what other possibilities there are, and if they’re really fit for this kind of use

haha sounds fun! Never tried it though , but if you build the extrusion proper (really decent with a solid motor that can run long) it should be doable.

oke thanks for the reply Dave! and as a last question how long did it take you to make the beam in the instruction video (as a reference) and was the output from the machine at that time at it’s max?
Thanks on advance!

He @casb 🙂

200 beams are quite alottttt, maybe you could make a longer mold and cut it up afterwards. ( someone suggested that idea to me 😉 )

maybe also @suzanne can tell you some more, at PP den haag they have really seem to be doing some propper production.

Keep us updated!

Hi @casb,

When do the beams need to be finished :3? Sounds tough, but do-able. If I were you, I would say yes, just for the hell of it :P. I think the hardest part will be to get shredder, extruder done before the end of this year (big thumps up you can make before that deadline!), to get enough recycled plastic for 200 beams and then creating the beams, which is sometimes trial and error.
We did 10 beams of approx. 1.2 meters in 3 days at the exhibitions, including: collecting, cleaning, sorting, shredding plastic and then melting it with the extruder (don’t forget talking with visitors) by 2 persons. It takes approx. 15 min to create 1 beam of 1.2 meter with the extruder. I double dare you to do better than us 🙂

If you have further questions, you can always contact us! And let us know the results,

hey @jerzeek and @suzanne

jerry, What a brilliant person that must be!

suzanne, He sad that if I would be able to finish them around the end of January, It would be fine.
and I take the challenge! (i do hope I will get the machines done in time)

thanks for your reply!
