The project consisted of studying melt flow characteristics of plastics and how the die structure should be set in order to get the desired shape. After the die has been de-signed on 3D Solid edge Design software it was simulated on COMSL flow Simulation software. On the Simulation software it was easy to study how the melt flows and in which part of the die is the shear stress and strain strong and weak.

In injection molding the purpose of the screw extruder is simply to obtain a melt, a ded-icated extrusion machine works on the same principle but also must mix, homogenize and melt the material. Higher back pressure may be generated in single screw extrusion machines compared to injection molding machines and the screws may be longer for
