Sandwich injection molding
WebbThe sandwich injection molding process is defined, that two or more polymers are injected one after the other through the same gate in one or more cavities. A thin boundary layer of the first injected material solidifies. The core remains plastic. The second now injected material fills the core. Webbusing the sandwich injection molding process Sandwich injection molding – a long standing tradition In sandwich injection molding, two different materials are injected in quick succession to give parts a 3-layer structure. The core material is completely enclosed by an outer shell.
