摘　　要：以汽车保险杠为例,分别采用普通热流道和热流道顺序控制技术对充填过程进行了流动模拟,将其结果进行了比较,结果表明:采用热流道顺序控制技术能有效消除熔接痕和气穴,提高产品的表观质量,同时降低了锁模力。采用顺序阀控制技术对大型复杂制品注射成型有着实际意义。Taking the car bumper as an example, the common hot runner and hot runner sequential control technology were respectively used on the filling process flow simulation. The result showed that sequential control technology could effectively eliminated the weld line and air traps thus to get the products with high quality and reduced clamp force. The sequence control technology was great practical significance to large-scale products of injection molding.
