Two-color injection molding, shaping how? The so-called two-color 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. Molding, the melt is plasticized in the barrel after a good, controlled by opening and closing the valve 2,4 melt into the exhaust nozzle of the order and the proportion of large color injection molding material, 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 plasticizing cylinder 1,5 respectively different colors melt, and gear driven rotary axis 3 4 rotation, so that the different colors melt into the mold cavity alternating double injection molds, resulting in the center surrounded by a form of radiation to the Different colors and patterns of 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, and therefore, from the two barrel melt must have good bond strength, in order to ensure a better bonding strength, should try to use different colors of the same kind of plastic. If using a different color varieties of plastics injection molding, you must combine performance tests carried out to confirm the order after production combined with qualified, otherwise, the bond strength of two bad plastic mix, easy to make plastic parts, cracks and other defects. Advantages of injection molding: horizontal injection molding machine is the most basic form of an injection molding machine at home and abroad, which is characterized by a template injection screw axis motion axis and clamping bodies were arranged horizontally on the ground. Horizontal injection molding machine has the following advantages: lower body, more convenient operation and maintenance, the machine is relatively low center of gravity, the work is relatively stable, mold installation, operation and maintenance are more convenient, the products can take advantage of the weight of the top of the action automatically fall easy to automate. Horizontal injection molding machine used widely Shenzhen color injection molding of large, medium and small machine types are applicable, its main disadvantage is more difficult to place inserts, covers an area of ??relatively large. Features vertical injection molding machine is a template motion axis and the axis of the injection screw clamping mechanism of vertically aligned front line. Vertical injection molding machine has the following advantages: a relatively small footprint, easy to place inserts, convenient mold disassembly. The disadvantages are: easy automatic ejection after products fall, we must use manual or robot will remove products, easy to achieve fully automated operation, due to the higher body, the poor stability of the machine, feeding more difficult, maintenance inconvenience. Vertical injection molding machine for minicomputers, large and medium-sized injection molding machines should not be used vertical structure. Of course, there are other injection molding machine in the form of, for example: angle type injection molding machine. Diversification of injection molding machines also contributed to the rapid development of plastic injection molding industry.
