Multi-color injection molding machine development trend inventory

Enhance the commercial value of a product, the common way is to print the logo of a well-known brand, in addition to the relevant printing, some times we may also use the multi-color injection molding technology for the beautification of goods processing. So, what is multi-color injection molding technology, multi-color injection molding technology in the future? The following Fengtie Jun to introduce the development trend of multi-color injection molding machine and related principles.

Multi-color injection molding technology principle

Multi-color and multi-material injection molding process refers to the combination of several plastics into multi-functional parts in one manufacturing process or one production unit. As with conventional injection molding, multi-material injection molding uses materials with melting points or near melting points so that semi-liquid (viscous) materials can fill the voids and cavities within the pre-processed molds, and the molded products have a variety of independent polymer colors in addition to forming a single structural part with different areas of material.

Multi-color injection molding technology application status

Automotive lamps: multi-color injection molding technology can be applied to the production of automotive lamps, lamps are generally composed of base and shell, the base material is usually thermosetting material - BMC (Bulk Molding Compound), the shell can be processed from PMMA, PP, ABS and other materials, usually two-color or three-color. In terms of the production process of two-color lamps, special attention should be paid to the injection part of the two-color injection molding machine, the center distance of the two screws and the center distance of the two-color molds should be relative to each other.

Multi-color keycaps: from hand will start, multi-color injection molding technology can also be applied to the production of keyboard keycaps, will be two different colors of plastic fusion together (usually black and white), so as to form the keycaps on the printed word. The main features of this type of keycap are: high gloss, smooth and delicate feel, and not easy to scratch. It is worth mentioning that this type of keycap, even if the cost is high, can keep the characters on the keycap from fading and wearing out. Therefore, it often becomes a hot choice for many gaming enthusiasts.
