Abstract
An automotive component (10) and a method for manufacturing the same are disclosed. The component (10) comprises a core portion (14) formed of a first material and a second portion (18) integral with the core portion (14) and formed of a second material. In one illustrated embodiment, the first and second materials have different material property characteristics. For example, the first material can be made of a relatively harder plastic material than the second material made of a softtouch plastic material. The method for manufacturing the component comprises the steps of injecting the first material into a first cavity of a mold to form the core portion (14), altering the mold cavity to form a second cavity and injecting the second material into the second cavity while the first material is in a reactive state to form the second portion (18) of the component. Because the first material is in the reactive state, the second material is integrally formed with the first material.
