| The Gas-assisted Injection Molding (GAIM) is a new molding method of plastics products, which was developed on the basis of the traditional injection molding technology. The research of Gas-assisted Injection Molding in China is behind the other country. Moreover the sensitivity of GAIM theory is great, and the prominent is more than the traditional injection molding technology. So it's require interferes and restrict among the parameters to find a way that can direct the product design, mold design and process variables setting and more to find the process variables that effect product molding and how to make the best use of the analyzing result of CAE, which has active effect on the spread of GAIM theory.This paper uses orthogonal experimental designing and molding CAE technology to optimize the product instruction design and molding design, sequentially to find the best molding design. It also discusses how to optimize the parameters of product molding by analysis several group tests result, and find the best parameters setting. The primary works include:Designing and producing a suit of molding, which is the combination of tube and slab, and using several groups of tests to analyze the trend of each factor that affects product quality. Arranging a group of orthogonal experimental, analyzing and finding out the best level of factors. The effect is satisfactory by molding several products by using the result of test. The validity of the orthogonal experimental method to GAIM technology was proved.Using the CAE simulation software analyzes the process variables setting of the test, it's in line the availability with the test result that also proves the reliability of the simulation software. Simultaneity finds out the difference between simulation and test, which verified the simulation software. |
