Multi-material injection molding

In other words, it creates a sandwich-like structure where both materials mold around each other as dissimilar liquids, and exist in such a state at the same time.

Relative to the part center, materials can be injected concentrically using the same mold/gate, or regionally using gates at different locations.

While there are other applications, this operation is preferred when varying molds (different geometries) are desired between material layers.

This process is centered around the use of a liquidous resin to add additional layers of shape and structure to an existing component.

This process works well when layers with varying geometric profiles are desired around a central "core" structure.
