Two-color injection molding, shaping how? The so-called two-color injection molding, refers to two different colors of the same mold plastic injection molding method. It makes plastic parts appear two different colors, and make plastic parts presents a regular or irregular pattern moire-like color, plastic parts to improve the practicality and aesthetics. (1) shown in FIG. 1 double dither injection molding injection molding dual color mixing principle. It has two barrel, structure and use of each cylinder are the same as ordinary injection molding barrel. Each cylinder has its own communication channels and nozzles, nozzle pathway is also equipped with four valves open and close. Double injection molding, melt in the barrel is plasticized completed, and the proportion of material discharged from the opening and closing valves 2,4 control melt into the nozzle of the order, and then by the injection nozzle into the mold cavity. You can get all kinds of different plastic products blending effect. Figure 1: Two-color mixing principle injection molding nozzle 2- 1- 3- feed Jane 4- closing valve closing valve 5- cylinder (2) double injection molding pattern 2 is shown in the schematic diagram double injection molding pattern. It also has two cylinder 1 and 5, the nozzle structure is somewhat special, in addition to its usual function of the nozzle, but also by a gear mounted on the rear of the three rotated. When molding, the barrel 1,5 respectively different colors plasticized melt, driven by the rotary shaft 3 and the gear 4 rotating color injection molding phone sets, so that the different colors of alternating melt into the mold cavity, whereby radiation from the perimeter to form different colors and patterns plastic products. Figure 2: Principle 1 Huan pattern molding a nozzle barrel 2- 3- 5- gear 4 a barrel rotary axis (3) Caution color injection molding injection molding because of color is composed of two barrel melt mixed molded together, so this comes from the two barrel melt must have a good combination of strength color injection molding phone shell, in order to ensure a better combination of strength, it should be possible to use different colors of the same kinds of plastic. If using a different color varieties of plastics injection molding, you must first test the binding properties of large color injection, in order to put into operation in conjunction confirm qualified, otherwise, the bond strength of two bad plastic mix, easy to make plastic parts, cracks and other defects . Color injection molding trends: from multicolor injection molding, co-injection molding double features and applications can be seen in the future to gradually replace the traditional injection molding process trend. Innovative injection molding technology not only improves the precision of the injection molding process, providing the difficult process technology, but also opened up the field of injection molding process range. Innovative injection equipment and process to meet its increasingly diverse, high-quality, high value-added product demand.
