The steps of the injection molding method comprises (a) fitting the injection molding machine with an injection mold (1) defining one or more molding cavities (8a, 8b, 8c, 8d), at least one of the mold plates (2, 3) are provided with one or more channels (11, 14) for circulation of a tempering medium, (b) providing a feed of plastic material having a first temperature within the processing window, (c) heating molding cavities (8a, 8b, 8c, 8d) to a second temperature within the processing window circulating through the one or more channels (11, 14) a first tempering medium having a third temperature, (d) injecting plastic material having the first temperature into the closed heated mold (2, 3) to fill the molding cavities (8a, 8b, 8c, 8d), (e) cooling at the molding cavities (8a, 8b, 8c, 8d) of the filled closed injection mold (2, 3) to a fourth temperature below the first temperature until at least partly solidification of the molded plastic parts by circulating through the one or more channels (11, 14) a second tempering medium having a fifth temperature, (f) opening the injection mold (1) by parting the injector plate (2) from the ejector plate (3), (g) ejecting the at least partly solidified 25 molded plastic parts by actuation of ejector pins of the ejector plate, and (h) repeating the cycle of steps (c) – (g). |
