Polyacetal was combined with polyacetal, fiber reinforced polyacetal and fiber reinforced polycabonate by a simultaneous composite injection molding (SCI. Molding) in which two different melts can be injected into one mold cavity simultaneously through two individually controlled channels. The structure and properties of polyacetal sandwich moldings were investigated as a function of molding conditions. Impact strength and mold shrinkage were strongly affected by the crystalline morphology of polyacetal. Bending properties and dimensional stability of the polyacetal composite moldings were improved by sandwich molding.
