Method and apparatus for forming an article from recyclable plastic materials

摘要: A method for forming an article from recyclable plastic materials includes progressively heating thermoplastic solid particles simultaneously with mixing, melting and conveying the particles, prior to delivery of molten material extruder. The process is particularly suitable continuous extrusion elongated members having a plurality internal wall surfaces defining cavities within member. apparatus embodying present invention heated mixer-conveyor that heats, melts, mixes conveys inlet port at which received in particulate form, discharge substantially liquid state. die adapted member walls shaped by cavity also disclosed.
