Design and Implementation of an Extruder Machine to Recycle Waste Plastics

Abstract

With increasing in global consumption and retreating of natural resistance, concern is growing over widespread plastic waste. Plastic waste threatens the environment when buried in landfills. Further, when such plastics are burned, quantities of harmful gases are emitted and this can increase chronic diseases. As a result, the project works on the design and manufacture of an extrusion device by CATIA, in addition to all the components that it chooses, it has a transition system (screw), the storage System (Hopper), (PID temperature control) to control the temperature of the system as required, and the variable frequency driver, in order to control the speed of the motor that rotates the screw. The selection of plastic materials was (high-density) was to do experiments on it and on the results, and that by put these thermoplastic in the hopper of machine after this machine reaches to proper working temperature, then these materials enter the machine and its temperature will increase by heaters and by friction with the boundaries of chamber until it reaches to 200 degrees Celsius , this will transform it into a plastic paste , then it will go to nozzle by the rotation motion of screw and it will output as a continuous lines of raw plastics in various diameter as want , these can be exploited in various areas such as 3d printing filament
