Status:	experimenting stage
Initiator:	Massi
Materials Used:	various thermoplastics
Tools Used:	plastic shredder, drying oven

Massi has begun experimenting with plastic beams made from self-shredded recycled plastic flakes.

Open Mold Method

To make beams without special machines, you can use a mold which is open on one of the long sides. Molten plastic is filled in and pressed into the mold with a matching "fourth side" piece.

rough process
molten plastic in a baking pan
filling the mold with heat-resistant gloves
not ideal, but allows for longer molds: diagonal mold heating
finished beam

[missing: shreds(?), pressing(?), finished beam]


mold type	mold size	plastic type	plastic in [g]	temperature [°C]	duration	beam size	notes
welded steel	50 × 4 × 2 cm	PP	350	240	approx. 2 h (?? min baking pan; ?? min mold)	49 × ? × ? cm	near the Memmert oven's limits (only fits diagonally)
