Large profile extruder from recycled plastics

Looking for a machine to extrude a 20cm square hollow profile from used plastics
The experts are telling me I can’t extrude from recycled plastics but this product has curved walls and doesn’t require a high finish product just a strong one.

never seen the product exist in precious plastic community, big product need big machine… but this might help got some inspiration…

Hi ; @halimwidyakusuma they are using industrial extruder which is not a cheap option to recycle plastic unfortunately.
