double color injection molding processing is a part with two kinds of plastic injection molding. Generalized double color injection molding, including through the normal injection molding machine, injection twice, narrow bi-color injection molding is refers to the use of double color injection molding machine, the two different kinds of plastic in the same machine injection with component, common is rotating. Two-color injection molding, not only require simple combination of two or more colors of plastic, and in different color plastic products accuracy, good appearance, better integration, products molding cycle of injection molding machine on and put forward the higher request.
but, as a result of the double injection molding material variability is very high, so to achieve the production, in line with expectations ideal, all of the mold design must consider, with product design and market popular double material injection molding machine specifications are not unified, cause mould design when considering more; With less commonality, mold manufacturers must redouble their attention. Double material goods generally with the TPE with ABS, PC and other hard plastic soft plastic is given priority to, suitable for manufacturing tableware, tool handles, watchcase, telephone shell and buttons and other products. This makes production enterprises must pay attention to three things: technically the complexity of the fusion of two kinds of material, product and injection molding machine set-up.
double color mould, two kinds of plastic material in the same injection molding machine injection molding, two forming, but the product out of the mold only once the mold. This is also called the double injection molding process, usually performed by a set of mould, and need special double color injection molding machine. Double color mould is becoming more and more popular on the market at present, in this process can make the product more beautiful appearance, easy to change color and can not spray, but expensive, high technical requirements.
double color injection molding requirements
double color injection matching material must meet two basic compatibility condition, glue compatible process compatible. In addition, you must meet the following requirements:
1. Injection unit, parallel to the direction, parallel to the horizontal and vertical L, Y type synthetic single cylinder injection structure;
2。 Mixing nozzle, decorative pattern, waves, flow mark, gradually layer, interlayer and other special nozzle;
3。 Die, standard, vertical rotating disk, horizontal rotary disc, rotor, manipulator etc;
4。 Material, in addition to the standard hydraulic motor drive, and ESD ( ElectricScrewDrive) Electric charging structure;
5。 Oil, ACC accumulator injection and closed loop design at a high speed.
the choice of two kinds of plastic raw materials
double color mould injection molding often choose different colors of the same kind of plastic, also can be two different kinds of plastic raw materials, the time of interaction to consider two kinds of materials, the difference of shrinkage rate, processing parameters, etc. In general, double color mould shrinkage depends on the material at a time. Because of one material has been shored up the outline of the plastic products, the secondary material doesn't shrink more. As for how to determine a material and secondary material, there are many factors into account, such as raw materials, liquid plastic products shape and so on.
the choice of double color mould
double color injection mould rotation is often used to injection mold. Rotating injection mold two positions on the convex mold/die required size, precision, and cooperate with die/punch is good. When not using ejector demoulding mechanism of double color injection molding machine, rotary table, hydraulic ejector demoulding mechanism must be set.
