PLASTIC EXTRUSION MACHINE

Plastics produced and used by the human beings eventually end up in the nature causing harm to living beings and the enviroment. The amount of plastics recycled than the plastics produced is very much less and the requirement of plastic recycling and upcycling is now an assential task. This project is about the design and fabrication process of plastic extrusion machines which address the plastic recycling. This small tableshop extruder is just a small step in recycling the huge plastics products. The small table top plastic extrusion is designeed. Yhe initial design consists of different components like hopper, screw, barrel, die, and motor system. The plastic pellets are fed through hopper which are moved forward using the rotating screw driven by suitable sized motor. The friction between the pellets and barrel surface along with the external heat given by the band heaters melt the plastic pellets and pump through the die. If the temperature is not enough then the product is not good and fine as expected and the melt get pasted in the barrel and when the different type of plastic pellets is used in ectrusion it result in the mixture of two types of plastic. So , temperatue maintenance is very important. This prototype is designed in such a way that any people interested to make plastic ectrusion machines can follow the prodecure mentioned in this report.
