【 摘 要 】

Nowadays; Polymers products are in the way to replace many metal products due to their low cost, light weight, easily production and suitable durability. In plastic injection moulding; the problems of products sticking inside the cavity and the highly importance to keep the products in dimension stability without any distortion during removal needs to be solved. Also the problems of removing a thin wall products form cavity needs optimizing the design of ejection system based on smart modelling and simulation techniques. For these purposes; commercial finite element software (ABAQUS/CAE) has been adopted for developing a F.E analysis model to estimate the parameters which has major effects on this process. Towards more understanding and to enhance the results, a two cavity mould has been fabricated to produce a thin product, and then tested by suitable injection machine. Simulation results was valuable for early prediction and identification the weak regions where the stresses consternation are in maximum values. Also simulation results were highly desirable in optimizing the design and for reducing time and cost at the design stage, such as experimental characterization. Comparison was made between simulation and experimental results and that was valuable for building new recommendations to the future. It can be also concluded that; the properly designed parts can not only enhance the performance of information technology equipment but also positively impact the disassembly and recycling of the finished product.
