Abstract

Extrusion is a process for making continuous forms by forcing a thermoplastic material in the plastic state through a die. In Extrusion, plastics are fed through a hopper to a heated plasticizing cylinder where they are melted, then driven by rotating screws through a shaped die that determines the shapes of the extruded part. The process is used for the fabrication of pipe, flexible tubing, rods, sheets, tubes, house siding and other shapes. Hot isostatic pressing is a manufacturing process used to reduce the porosity of material and influence the density of many materials. This improves the mechanical properties, workability and density of the material. The mold for hot isostatic press is 2 mm thickness and 3 mm thickness. For this project the extrusion process and hot isostatic press would give a temperature to the material and we can see it will change the mechanical properties for the all composition material. In this case the mixing process it can improve all the composition of the combination polymers. The extrusion process for this combination material the ABS blends with PVC make a higher torque compare to other material. The different composition makes it better bonding compare to main material. It’s because of the extrusion process can set the parameter for the speed and temperature melting point based on material. This experiment for the main material ABS is the good mechanical properties compare to the others combination.
