The so-called two-color injection molding refers to a molding method in which two different color plastics are injected into the same mold. It can make two pieces appear in plastic parts
Different colors, and can make the plastic parts have a regular pattern or irregular cloud-like colors to improve the practicality and aesthetics of the plastic parts.
It is connected with the nozzle, and an opening and closing valve is also installed in the nozzle passage. After the molding is finished, the melt is plasticized in the cylinder, and the order of the melt entering the nozzle and the proportion of the discharged material are controlled by the opening and closing valve, and then the nozzle is used. Injection into the mold cavity. You can get a variety of plastic products with different color mixing effects.
Double color mixing injection molding
It has two barrels, each of which is constructed and used in the same way as a conventional injection molded barrel. Each barrel has its own channel
Two-color mold: Two kinds of plastic materials are injection-molded on the same injection molding machine, and molded in two parts, but the product only molds once.
Have the following requirements:
Paired materials for two-color injection molding must meet two basic compatibility conditions, namely, adhesive compatibility and process compatibility.
Generally, this molding process is also called double-material injection molding, usually completed by a set of molds, and requires a special two-color injection molding machine.
