Lightweight design and manufacture is an important direction in automobile development. This paper researched the lightweight method of interior part by using OptiStruct software and rapid heating and cooling molding technology. Taken the real sill plate trim as the research object, the application of this method reduced part weight by 19%. Taken the new part to do the strength test, dimension stability test and scratch and mar test, the results validated the superiority of the new Lightweight part. The study shows that, plastic parts performance is better than before and cost is lower, and also economic benefit is remarkable.%轻量化是汽车发展的重要方向,研究了汽车内饰件轻量化设计及成型方法.通过OptiStruct工具指导轻量化设计,通过高光无痕注塑成型技术提升零件的成型质量.以汽车后门槛饰板为研究对象,应用此方法成功的将汽重量降低19％以上,并通过强度、尺寸稳定性、外观、耐刮擦等试验,验证了轻量化之后的零件的优越性.研究结果表明:塑件在轻量化设计成型之后性能升高、成本降低,经济效益显著.
