What Is Multi Component Injection Molding?

Two-Shot Molding and Tool Design | Plastics Technology

Oct 18, 2016 · The mold closes and injects the first shot; then the first-shot core/slide is pulled, the second-shot core/slide is set, and then the second shot is injected. There are cases where there is just one core/slide, which pulls back after the first shot and creates the cavity for the second shot. In either case, the setup and process are the same.

TWO-SHOT PROCESS Same process as a traditional plastic injection molding machine except add in an extra plastic injection unit and a rotary table. Once the injection process is complete, the mold opens, ejects the finished part and then rotates the live side of the mold 180 ̊, so the bottom cavity will be injected with the second shot.

Multi-shot Injection Molding : Plastics Technology

Multi-shot injection molding also known as twin-shot injection molding, is a process where two or more colors and / or materials are injected simultaneously into a mold, creating one or multiple components. Essentially, the molding process remains the same as traditional injection molding. However, the integration of additional injection units is required.
