Abstract: New advances in screw design and mixing sections have allowed processors to take advantage of new resins, higher production rates and improved product quality. The three main zones – compression, mixing, metering, of extrusion process must be considered while designing the extruder. The L/D ratio plays an important role in designing the screw. Material selection, power required, melt viscosity, and other important parameters are determined/calculated using suitable formulae. This project aims at designing a low- cost, portable single screw extruder. The main objective is to compact the size of the machine without harming its ability to extrude
