Abstract

This Bachelor Degree project presents a study on design and development of plastic injection mould with concurrent engineering. The application of concurrent engineering process to the design of an injection process involves the simultaneous consideration of plastic product design, mould design, and injection molding machine selection, production scheduling and cost as early as possible in the design stage. The advantages of concurrent engineering are reducing the development cost and shorten the lead-time. Product can be market with short time and good quality. This project uses a product, which has been model with CAD software as a case study and will incorporate concurrent engineering methodology. Many of the design tasks were carried out in the parallel process. The product design has been tested with the CAD software like Mold Flow analysis and Structural Analysis. Then the shortest plastic injection time was found which 1.11 second is. Therefore short injection time can reduce the cycle time. Meanwhile, the mold cost can be reduced. The results of this project shows that the side injection location, shortest runner length 40mm, small runner diameter 4mm and high melted temperature 250 ºC can achieve the shortest plastic injection time. Thus, by using CAD software and the implementation of concurrent engineering improve the quality design of the plastic part and reduce the lead time, cost by reducing mold development time and enhance cooperation between the designers and manufactures.
