在研究塑料制品注塑成型的过程中,常常将注塑分为两个阶段:在第一阶段,大部分塑料充入模具中,一般为整个制品体积的90%～99.9%;在第二阶段,压实制品,得到与模具结构和外形相同的制品。在第二阶段,虽然只有相对较少的塑料熔体充入型腔,然而对制品表面的光洁度、美学外观以及制品尺寸来说非常重要。在大多数情况下,注塑成型的第二阶段使用压力和时间两个参数。从科学成型的研究角度,我们将两个因
In the study of plastic injection molding process, injection molding is often divided into two stages: in the first stage, most of the plastic filled into the mold, the volume of the entire product is generally 90% to 99.9%; in the second stage, the pressure Real products, get the same structure and shape of the mold products. In the second stage, although only a relatively small amount of plastic melt is filled into the cavity, it is important for the finish, aesthetic appearance, and product size of the article surface. In most cases, the second stage of injection molding uses both pressure and time. From the perspective of scientific molding, we will be two factors
