摘　　要：卫浴制品生产行业需消耗大量优质塑料原料,而多层制品结构固有的缺点并不适合于卫浴制品。通过对夹芯共注成形原理及特性的分析,在马桶盖产品的设计及制造中使用夹芯共注成型技术,夹芯共注成型产品中二次料质量约占总质量的40%,节约大量优质塑料。文中指出卫浴等其它优质塑料消耗量大的行业,采用夹芯共注成型技术,可大量利用生产过程中产生二次料和回收塑料,降低产品制造成本。Sanitary products industry generating needed a large number of high-quality plastic materials, but the inherent shortcomings of muhilayer structure were not suitable for bathroom products. Through analysis to principle and characteristics of sandwich co-injection molding, the toilet seat product design and manufacturing used sandwich co-injection molding technology. The qualities of reclaimed materials of sandwich injection molding products were in the total mass of about 40%, saving a lot of high-quality plastic. The paper pointed out that the sanitary and other industries consumed a large amount of good quality plastic, if using reclaimed material and recycling plastic by sandwich co-injection molding technology, the manufacturing costs could be reduced.
