| Abstract | Metal Additive Manufacturing (MAM) has had a tremendous impact in reimagining the design and manufacture of products in a number of industries. The use of MAM to directly produce products continues to be investigated; however, the area of manufacturing tooling has yet to be fully explored. MAM provides a unique opportunity to introduce features that make manufacturing tooling better equipped to efficiently produce complex products. A recent example includes MAM produced molds for the injection molding industry. MAM, in this case, provides the ability to introduce unique features, such as cooling channels, that could not be introduced practically with SM processes. This study explores the use of MAM towards the engineering and design of Extrusion Die Tooling for plastic extruded products. Plastic extrusion is a high-volume manufacturing process for a broad range of products from tubing to window frames. These extruded plastic products come in not only a range of sizes, but also different polymer materials. A series of extrusion dies are currently needed in the process in order to achieve the final shape of the product. These dies are effectively designed in two dimensional Computer Aided Design (CAD) packages, because of the current preferred method of fabrication, wire Electrical Discharge Machining (EDM). This study explores the effect of MAM on the extrusion die engineering design process. The explored cases center on common extruded plastic products including tubing and constant wall U-channels. The study first describes how sets of extrusion dies are currently designed in CAD in order to produce the desired extruded product features with established advanced manufacturing processes (EDM). The study then details the effect of using the MAM alternative on the design process, CAD methods selected, and the extrusion die features. The impact of MAM on the extruded die design process are discussed in order to provide guidelines for when it should be considered in order to effectively achieve features on the described extruded plastic products. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
