Two-shot molding produces components with multiple materials or colors molded together in a single cycle. This can support complex part designs and integrated features while reducing the need for separate molding operations. Midwest Molding supports the process with dedicated manufacturing and project engineers, including assistance from tool build through production ramp-up.

Insert molding combines a pre-existing insert with injected plastic to create a finished component.
