injection molding parts products internal stress 包括两 types:一 types is injection molding parts products molding force,另一 types is temperature degree force effect/influence internal stress process factors for orientation force effect/influence in speed cold conditions lower, orientation 会导致 polymer internal stress formed. melt temperature degree high, viscosity low, orientation degree reduce, 另一方面, due to melt temperature degree high make force add fast, make understanding orientation can force add strong/high. long holding pressure time 会导致 orientation pressure increase. improve/increase injection pressure, holding pressure pressure, increase large orientation pressure. material 变脆 几 types 状况.
