Seamless insert molding techniques

摘要

Methods and apparatus for using an insert molding process to form a tactilely seamless overall part from component parts that are made from different materials are disclosed. According to one aspect of the present invention, a housing includes a first part formed from a first material and a second part formed from a second material that is of a different type than the first material. The first part includes a first external surface and a first bonding surface, and the second part includes a second external surface and a second bonding surface. The second bonding surface can be integrally bonded to the first bonding surface so that the first external surface and the second external surface form a gap-free overall surface.
