Handbasket

A method of injection molding at least one part in a single mold having therein at least one cavity, the method comprising providing first and second injection molding devices, using the first injection molding device to inject material into the single mold, and thereafter using the second injection molding device to inject material into the single mold.

Injection-molding system and method

A medical suction system comprising a medical suction canister used in draining bodily fluid from a patient, and a cleaning station for automatically draining and cleaning the suction canister and for automatically providing a visible indication that the canister has been cleaned.

Medical suction system

A co-injection nozzle pin () having downstream and upstream ends. The nozzle pin has therein a central bore () including an upstream end () adapted to communicate with a first material and a downstream end () exiting at the downstream end of the pin. The nozzle pin also has an outer surface () including a first portion () having a diameter D, a second portion () having a diameter D, wherein Dis less than Dand the first portion is rearward of the second portion. The pin further includes a channel () spiralling around the outer surface and being adapted to communicate with a second material. The channel () includes a first segment () defined in the first portion () of the outer surface and increasing in depth as it travels in a downstream direction and a second segment () defined in the second portion () of the outer surface and decreasing in depth as it travels in a downstream direction.

Co-injection apparatus for injection molding

The invention provides a method of co-injection molding. The method includes mixing a plastic inner material and an endothermic-blowing agent to form a core mixture. A plastic outer material is injected from a first injection unit into a co-injection manifold to create a flow of outer material therethrough. The core mixture is injected from a second injection unit into the co-injection manifold to create a flow of core mixture therethrough. The flow of the outer material and the flow of the core mixture are then controlled through the co-injection manifold and into a mold cavity. The core mixture expands as heat is provided for the endothermic-blowing agent to absorb.

Co-injection methods using endothermic-blowing agents and products made therefrom

Injection molding apparatus including a first mold cavity having an inlet, a second mold cavity having an inlet, a source of a first material to be injected, a source of a second material to be injected, and a co-injection manifold including a nozzle housing including a first outlet adapted to communicate with the first mold cavity inlet, a second outlet adapted to communicate with the second mold cavity inlet, first and second spaced apart inlets respectively adapted to communicate with the first and second sources of material to be injected, a first passageway communicating between the first inlet and the first and second outlets, and a second passageway communicating between the second inlet and the first and second outlets.

Co-injection method apparatus for injection molding

A method of and apparatus for determining if a given data point having three parameters falls within a population defined by more than four known data points, each data point having the three parameters, the method and apparatus involving determining if the given data point falls within any of a plurality of tetrahedrons, each of the tetrahedrons having four vertices, each of the vertices of each tetrahedron being defined by one of the known data points.
