摘要
用ABS(丙烯腈-丁二烯-苯乙烯)制备的倒车灯灯体经注塑成型、喷涂紫外光(UV)固化油漆、固化和真空镀铝后,在装配时发现灯体变形缺陷。从注塑工艺、真空镀铝技术、光固化工艺这3个方面分析了产生缺陷的原因。主要是UV室温度过高,超出了灯体材料的热变形温度。通过稳定UV灯的能量、控制固化室温度、调整油漆、完善注塑工艺、加强产品检查等措施,较好地解决了灯体变形的问题。
The reversing lamp body, which was made of ABS （acrylonitrile-butadiene-styrene copolymer）, was found to be deformed at assembling stage after injection molding, painting ultraviolet （UV）-curable coating, curing and vacuum aluminum plating. The reasons for this defect were analyzed from three aspects including injection molding, vacuum aluminum plating and UV curing processes. The main reason is that the temperature of UV chamber is excessively high, beyond the heat deflection temperature of lamp body material. The deformation problem of lamp body was solved by steadying the energy of UV lamp, controlling the temperature in UV chamber, adjusting the composition of paint, improving the process of injection molding and strengthening the inspection of product.
