Mold can be two different color characteristics of the resin and color, as a single-color products that can reduce the molded product group legislature and post-treatment works. Saving the cost of printing dissolved, increase the aesthetic visual effects products to enhance the quality and value-added products. Not only have non-slip, increasing the friction function, flexible resin material to make it more ergonomic feel better. Color injection molding products of high quality stability, distortion product easy to control, high yield short cycle times, lower loss than overmoulding 7% lower manufacturing costs than the plastic bag 20% ??-30% color injection molding usually refers to two color or a different type of plastic molding, two-color machine due to injection unit and the nozzle is handled separately, so the color of the finished color is mostly clear, no mixed together. Two-color injection molding machine with a general injection molding machine biggest difference is the injection unit machine activity template design. Generally speaking, there are two independent color machine separate injection unit, generally only one set of injection molding machine injection unit. Two configurations of the two injection units with the manufacturers of the design and a variety of forms, as the activity template design is necessary to provide a mechanism to rotate the general common design such as increasing the dial or shaft mechanism, so as to provide a 180 ° reciprocating rotation, so that the mold to produce cycle alternating movement. Some of its other special color mode dial or shaft mechanism is not required, but the mold or alternately sliding horizontal rotation. 1. The structure consists of two color injection molding machines, plastics injection device specifications are identical components. Nozzle according to production needs to be its special structure, or with a transposition of the structure can be rotated two identical mold. When plastics injection plastics injection device requires two sets of melt temperature, the same injection pressure, injection quantity melting process parameters, to minimize fluctuations in process parameters means the difference between the two sets. 2. The two-color injection molded plastic products as compared with conventional injection molded plastic products, melt temperature and injection pressure during injection which have a higher parameter value. The main reason is two-color injection molding mold runner longer, more complex structure, injection melt flow greater resistance. 3. The two-color injection molded plastic products to choose good thermal stability, low melt viscosity of materials in order to avoid high melt temperature in the flow channel to stay longer and decomposition. Application of more plastic is polyolefin resins, polystyrene and ABS materials. 4. In the two-color plastic injection molding, in order to make two different colors can be well melt in the mold during molding weld to ensure quality of injection molded articles, should be relatively high melt temperature, high mold temperature, higher injection pressure and injection rate.
