Large-scale plastic is mainly manufactured by injection molding, the major deflects for a injection-molded part such as automobile bumper with the characteristic of long strip and large curved face are warp, sink mark and weld lines.
大型塑件主要采用注塑成型,诸如轿车保险杠这类长条形大曲面特征的注塑件,其主要的成型缺陷是,成型后翘曲变形较大,影响产品的安装;局部地方有缩凹,影响制品的外观;个别熔接线较为明显,影响制品的强度和喷涂效果。
