The plastic is present in the product design is a material widely used. It is known for its rich colors, superior material properties as well as a variety of-forming way more and more designers and consumers alike. But along with the widespread use of plastic products, also appeared in the form of the various forms of the plastic member VALID. Even in the minds of consumers the wrong impression of plastic products can only be used effectively in the short term. To get rid of the arbitrariness in the design of plastic products, the products at the design stage to reflect a combination of scientific and economic This is an important part in the design of modern plastic products. This paper to analyze and explore some of the common factors causing failure of plastic products in the design to avoid the failure of the plastic products, in order to facilitate the design of plastic products, production in the application. Reduce manufacturing costs and improve the availability and reliability of the product. The initial part of this paper is the introduction part, mainly on the purpose and significance of the research to be reached, as well as to prepare main methods used in the study. The second chapter in the text analysis of the basic characteristics of some common plastics, as well as for plastic parts is the main method for processing, and attempts to analyze the characteristics of each of the processing method. The third part of the article the main factors causing the failure of a detailed analysis, focusing on the various failure factors underlying mechanisms, as well as calculation or analysis. In the fourth chapter, according to the cause of the failure analysis, as well as plastic parts processing characteristics, a detailed introduction to the choice of materials, structural design of plastic parts, as well as the main points of the spout design. The plastic parts on reasonable selection of materials and improved process performance some conclusions. Next, two representative cases, check the design is feasible in theory, and predicted after a certain period of time there may cause problems because the material creep. The research paper, I hope I can sum up the reasons for the failure of the plastic components and finishing feasible to avoid plastic failure analysis method. Get rid of the past the embarrassing situation assessment experience design. In order to improve the reliability of the plastic products, explore, to lay a foundation for further study in the future.
