Co-injection molding (also known as sandwich injection, co-injection molding) is a typical situation in multi-resin injection molding process. The injection equipment has more than two injection barrels, which can inject different colors or different materials in steps or at the same time, so as to obtain products with multi-layer structure, core-shell structure or different colors or different tr...
