Our Two-Color Injection Molding Services
In our Formioo plant, our proprietary two-color injection molding methods, such as sequential two-shot and overmolding technologies, are used to manufacture dual-tone products with optimal interfacial bonding and accurate color matching. These effective processes provide stable, high-quality components to the automobile, consumer electronics, and home appliances markets with quick turnaround and flawless reliability.
This process molds two distinct materials in sequence using separate injections within one cycle for precise color separation.
Both materials are injected concurrently through dual injection units, forming an integrated, dual-color part in a single cycle.
A second material is molded directly onto a preformed base, creating a durable, two-tone part with excellent bonding.
Preformed inserts are placed in the mold and overmolded with a secondary material, achieving functional and aesthetic dual-color components.
