金属射出成型过程中黑痕与熔接线现象建模与实验分析
Modeling and Experimental Analysis of Black Area and Weld Lines in Metal Injection Molding
摘要
Abstract
The 17-4PH stainless steel guide bushing used for medical was adopted to investigate the phenomenon of black area and welding lines in the metal injection molding,and the mathematical model was presented to analyze the influences of operating parameters such as injection velocity,holding pressure,material molten temperature and mold temperature on black area and welding lines.The response surface methodology (RSM) associated with the sequential approximation optimization (SAO) method would be used to obtain the optimum parameters of 17-4PH stainless steel.The results show that the effect of holding pressure on black area is far greater than that of injection velocity,but the increase of injection velocity is not conducive to reducing black area.Under the low mold temperature and high material molten temperature,the minimum of the black area is found,whereas in the high mold and material molten temperature,the area of weld lines is the smallest.The black area and weld lines are reduced by 78.81％ and 83.85％,respectively.关键词
