The Mold
We use a 95cm long stainless steel tube. We built it longer that what we needed the length to be because it always shrinks when cooled down.
The tube has an open end that way it can release de air that accumulate and we can see how the plastic is moving and when it reaches the end.
It connects to the extrusion machine using a clamp like they use in tubes for high pressure hot air. It was the best way to assure it had the strength to endure the pressure and the heat. The packing is made out of silicon which was the material that best endured the pressure and heat.
