A molded vehicle component () having a skin () and a lower density core () formed by a co-injection molding process. In a first phase, a first material for forming the skin of class A surface material is injected into a mold to partially fill the mold cavity (). Thereafter, in a second phase, a second material is injected into the same cavity () to complete filling of the mold cavity (). The second material can flow only to portions of the part where the first material is still molten and displaces the molten core of the first phase, pushing it away from co-injection gates until the mold cavity is full. The second material is pre-treated with a chemical blowing agent in order to reduce part weight by foaming the core material. The finished co-injection molded part () has one material on all visible class A surfaces () and a core () that is a different, less dense material.

Co-injection of molded parts for weight reduction

A vehicle bumper () integrates rigid and flexible components into a single co-injection molded structure. In a preferred embodiment, a flexible fascia () is provided with integrated rigid fastener brackets (), energy absorption structure and head lamp brackets and housings (). A method for manufacturing such a bumper provides for the injection of two different plastic materials during the same molding process. The flexible plastic material first injected into the mold. Then, the rigid plastic material is injected at gates located where the rigid material is desired. In one embodiment, the rigid material is completely contained within the flexible material. The rigid material may be either a higher stiffness plastic or a fiber reinforced plastic.

Integrated co-injection molded vehicle components and methods of making the same

The present invention (FIGS.) provides an injection molding method and apparatus. A hot manifold is provided having a plurality of independently controlled valve gates. A controller is operably connected to each of the valve gates enabling independent opening and closing thereof. A mold has at least two cavities, a larger cavity and a relatively smaller cavity. The larger cavity has at least two inlets each communicating with the valve gates of the hot manifold. The smaller cavity has at least one inlet communicating with respective valve gate of the hot manifold. The larger cavity is filled with a first plasticized material by sequentially opening and closing the valve gates communicating with the large cavity. The larger cavity is packed out. Simultaneously with the packing out step, the smaller cavity is filled and packed out with a second plasticized material by opening and closing the at least one respective valve gate. A large and a small part may be molded in the same time as required for molding solely the large part.

Multi-part sequential valve gating

A fluid collection and disposal system which includes a reusable collection unit designed to be cleaned by a servicing unit after use. The servicing unit performs an automatic servicing cycle to remove the collected fluid from the collection unit and prepare it for reuse.

Method for a servicing fluid disposal system

A fluid collection and disposal system which includes a reusable collection unit designed to operate in conjunction with a disposable manifold for collecting fluids aspirated from a patient during a surgical procedure, and to be cleaned by a servicing unit after use. The servicing unit removes the collected fluid from the collection unit and prepares it for reuse. The disposable manifold is removed from the collection unit prior to its attachment to the servicing unit, and a new disposable manifold is replaced on the collection unit after servicing.
