Problems with extruding PP beams – Help needed

16/10/2019 at 17:58

Hello PP community,

I am trying to extrude plastic beams for construction, in Maputo, Mozambique. Particularly, I am interested in developing a solution for roof structures, as plastic would have certain advantages compared to conventional solutions, e.g. not rotting or getting eaten by insects. I have setup a small workshop with a shredder and an extruder and we have run some tests but are facing some problems.

We are seeking to produce beams like in this video: https://www.youtube.com/watch?v=zNGuuSKE1pY

However, we haven’t been able to produce beams longer than 1,5-2 meters. The machine lacks capacity to fill up the mold before the plastic cools down and solidifies. Sometimes it clogs the mold and we have to make new molds.

Do you have any suggestions to how we can produce 3 meter beams, using our small scale machine? Or would i simply have to buy a machine with larger capacity?

Thank you in advance,
Johan
