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
