[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The so-called two-color injection molding refers to a molding method in which two plastics of different colors are injected into the same mold. It can make the plastic parts appear in two different colors, and can make the plastic parts present regular patterns or irregular cloud-like colors to improve the practicality and aesthetics of the plastic parts.
