He plastic molds for double 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 Shenzhen plastic mold, structure and use of each cylinder are the same as with ordinary injection molding barrel. Each cylinder has its own communication channels and nozzles, nozzle pathway is also equipped with 2,4-off valve. Molding, the melt is plasticized in the barrel after a good, controlled by opening and closing the valve 2,4 melt into the nozzle of the order and proportion discharged material, and then by the injection nozzle into the mold cavity. You can get all kinds of different plastic products blending effect. Sufficient abrasion resistance due to surface wear is one of the main failure mode of mold, the mold should therefore have sufficient hardness, wear resistance to ensure that mold plastic mold factory in Shenzhen, guaranteed life of the mold. Usually need to select the appropriate materials and appropriate heat treatment methods to meet the requirements of hardness. But hardness reaches a certain value plastic mold processing, enhance the role of the hardness of the wear resistance is not obvious. Reduce heat deformation effects due to injection-molded parts are often more complex shapes, plastic mold after the hardening process is difficult, and sometimes impossible process. In order to increase the hardness, must be subjected to heat treatment. To take appropriate measures to reduce the impact of heat deformation, must be processed for mold after heat treatment, heat treatment should be used in small material deformation.
