This thesis will integrate an innovation and product development process which its main purpose, it is to attend certain client´s requirements for a new product development by a thermoplastic’s extrusion company. By making a brief study over the main principles and definitions of thermoplastics extrusion and over product development department, will integrate both areas in order to create a systematically process for a new product development and can greatly enhance the development stage in terms of innovation, product design quality, future products value in marketplace, quality, and reliability. All the requirements will be measured and well analysed to be transformed into technical indicators. These requirements allow to identify all extrusion parameters like type of screw, proper thermoplastic, die and screw barrel´s temperatures, die shape, screw compression ratio, among others. Product development and innovation process on thermoplastic extrusion products, brings advantages to companies providing solutions faster than the competition using experience and constant knowledge as a weapon to guarantee products with high quality. Design stage it is considered as the most time-consuming task, however, throughout these entire labours of study and design, should be also back up with a significantly and well supported tests in an extruder. Such tests or essays were performed by an extrusion line, located at the IPL´s mechanical lab. The aforesaid extrusion line counts with an extruder, cooling bath, and puller. Plastic product designer must be concerned with the ability of the process to produce the level of detail necessary for the application. Beyond the fundamental design requirements, cost becomes the most significant factor in selecting the optimum process for the application. A well-developed innovation and design process will give extrusion industry great revenue, due to their principal goal is to develop a multidisciplinary and collaborative team that involves management, designing and production.engScrewExtrusionDesignDevelopmentThermoplasticsInnovationmaster thesis202286215
