    Abstract: The present invention provides apparatus and methods for injection moulding polymeric cannulae from liquid polymeric materials. The method includes injecting pressurised liquid polymer into a mould cavity and into an overflow and forming a conduit by forcing pressurised working fluid through the solidifying liquid polymer into the overflow. The invention provides a mould for fluid-assisted injection moulding articles from polymeric materials, the mould comprising at least two parts defining a cavity having a conduit portion incorporating a needle portion; a channel for liquid polymer ingress; a channel for pressurised fluid ingress; and an overflow in communication with the conduit portion. The mould may incorporate a plurality of cavities. Preferably the volume of the overflow is equal to or greater than the volume of the conduit portion. Preferably the mould incorporates a separating means for separating the overflow from a cannula portion of an article formed in the mould.

    Abstract: A plastic part is formed with a hollow portion and an integral evacuation channel extending from the hollow portion to a gate at which plastic for the part was injected. During the injection molding process for the part, the channel and portion to be hollowed are filled with molten plastic, and a gas is injected into the portion to be hollowed to force molten material from the portion to be hollowed back through the channel.

    Abstract: A process for manufacturing hollow handled toothbrushes is disclosed. The process includes; a) providing a toothbrush mold having a head portion, a base portion, a toothbrush cavity located between said head and end portions and having walls, an injection port for molten plastic, and a gas injection port, wherein the gas injection port is positioned in the end of the base portion of the mold so that gas is injected into the mold cavity substantially centrally thereof and in a direction parallel to the longitudinal axis of the mold; b) injecting a predetermined amount of a molten plastic into the mold cavity to partially fill the cavity; and c) injecting at least one gas through the gas injection port into the cavity to direct the molten plastic against the walls of the mold cavity.

    Abstract: The present invention provides a process for fluid assisted injection molding comprising the step of providing an injection molding apparatus having a mold body that defines a mold cavity. The process further comprises the steps of supplying a quantity of fluent plastic to the mold cavity, followed by injecting a fluid into the mold cavity. The fluid forms an expanding fluid pocket in the mold cavity, driving plastic to the furthest recesses of the mold and ensuring a smooth surface finish of the final molded product. A reservoir is selectively connectable to a plastic injection runner, and can be opened to the runner to receive molten plastic ejected by the introduction of the fluid to the mold cavity. When the reservoir is thusly connected, the pressure of the fluid forces the plastic through a supply passage, in a direction substantially opposite to its initial injection direction.
