薄壁泡沫塑料模成型工艺参数的研究

The Relationship between Technological Parameters and Pattern Density in Thin-walled Foamplastic Pattern Moulding

摘要: 针对大型薄壁件消失模精铸的特点,对消失模的成型工艺进行了大量试验。结果表明,成型工艺与模样密度相互制约,预发泡工艺可影响模样的密度,一定的模样密度又制约了其成型发泡工艺。对不同密度要求的模样,应采用不同的成型工艺。

Abstract: In this paper,a great amount of tests have been carried out on the technological parameters in thin-walled foamplastic pattern moulding.Results have shown existence of a dependance of parameters on the pattern density.The prefoaming process is able to affect the pattern density which,in turn,has effect on the pre-puffing processes.Therefore,different technological parameters should be adopted in accordance with pattern densities.
