发明名称 Method of molding a shopping cart
摘要 A method of molding a shopping cart component includes providing a first subcomponent and then overmolding the shopping cart component as a second subcomponent about the first subcomponent. The first subcomponent acts as an obstacle to a plastic injection stream and to a gas injection stream during the overmolding of the second component to assist in defining a first hollow section of the shopping cart component adjacent the first subcomponent.
