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.

The production of an injection moulding of plastics material that includes introducing a supply of plastics material through one or more openings in a mould space, and introducing by way of at least one gas supply passage, a pressurized gas through a separate opening in the mould space into the plastics material within the mould space whereby the gas creates a gas containing cavity in the plastics material. An opening and closing of the gas supply passage is controlled by a valve which is opened by the pressurized gas with the valve featuring a valve port at the outlet end of the gas passage, and a movable valve member extending longitudinally of the gas passage for opening and closing the valve port. The valve member at least when in its extended or valve port open position, protrudes into the mould space and penetrates the plastics material to assist the gas in entering the plastics material. Also, with the valve member in its withdrawn or valve port closed position, plastics material is shut off from entering the end of the passage from the mould space.
