Extrusion is by far the most common method used for the elaboration of PVC and PE pipes but thanks to the nature of the material certain modifications must be made to the extrusion system and design. Out of these, we focused on the wall thickness of pipes, Observed and analyzed all the relevant process parameter with the help of Taguchi method. The shape of the die, not a mold, determines the shape of the final product. Plastic extrusion is a reliable process for producing materials used in different industries. After the extrusion Process Many defects have been observed like, Wall thickness, uneven diameter, rough surface and low tensile strength. Typical extrusion problems fall into a few main categories: aesthetic flaws (e.g., pits, black specs, pinholes, drag marks, die lines, sink marks); size variance (which can be intermittent or contiguous); and dimensional variations. The domestic capacity for plastic production was Plastics extrusion is a normally high volume manufacturing process where a polymer material, enriched with the desired additives, is melted and formed in a continuous process. It may be enough for the environmentalists to keep it out of the landfill (although plastics are not toxic—none of them), but that shouldn't be enough for the accounting office.
