  • Plastic Smithing: How To Make your own HDPE Plastic Anything (DIY plastic lumber)

    Could I get opinions on whether or not my idea will work? -Use an induction cooker to heat a pan filled with HDPE material and a little oil to about 250 degrees. Heat and stir until evenly melted. (I think the induction cooker has the means to maintain a steady temperature.)-Make a wooden mold that uses a 2x4 for a bottom and has wooden sides and ends. Line the mold with parchment paper. -Pour (or drop) the melted HDPE into the mold. Lay a piece of parchment paper on top. -Place another 2x4 on top that's the exact same size as opening on the top of the mold. Clamp the top down and allow to cool. This should create a solid block of 2x4 HDPE. The length will be limited by how much HDPE I can melt at one time. I'm hoping I can create 2x4 lumber and build a small bench.
