Abstract
A staged coinjection molding process to produce a vehicular mud guard or similar molded article having regions of different mechanical properties. The process includes the steps of injecting a relatively small quantity of low flexural modulus (flexible) plastic resin to form a skin along the proximal walls of the mold cavity, followed by an injection of high flexural modulus (stiff) plastic resin. Finally, a second injection of flexible resin is introduced into the mold to force to stiff material to the distal region of the mold. This results in the two dissimilar plastic materials having a longitudinal interface to reduce the risk of delamination.
