Plastic defect analyses and solutions

In recent years, production and consumption of plastics achieved 200 million ton in the world. According to these improvements, responsibilities of plastic product designer engineers, mold production and plastic injection engineer gradually increases. Therefore, determination of the plastic product defects and precautions during design stage formed as the critical part of both responsibilities and competition.Literature part of this study contains important points of plastic product design, criteria?s of mold production and basic developments of plastic injection process.In experimental part; flow analyzed of a plastic component as the top cover part for satellite receiver was made by using Moldflow program. The analyze results were compared with real results and the success was achieved as averagely % 70-80 in all values.Moreover, certain defects in plastic item, which caused from design, mold production or injection process, were determined. The reasons of these defects were examined in literature part and the solution suggestions were proposed. Furthermore, results of these improvements on product were seen.As a result, considering of Moldflow flows analyze results before production step provides cost benefit from regarded to achievement of design, mold and injection processes.Key words: Design of plastic products, Moldflow flow analyze, mold design and production injection process.
