Abstract: A load bearing panel member having a first portion, a second portion, and an appearance surface portion is formed by injection molding such that the first portion includes a plurality of rib members forming a grid pattern on the first portion and another plurality of rib members extending toward the periphery of the first portion which may be non-orthogonal to each other and to the rib members forming the grid pattern. A tubular cavity may be formed within each of the non-orthogonal rib members by injecting a gas into the rib member during the molding process forming the panel. An appearance surface portion attached to the first portion and second portion of the panel member forms an integral hinge between the first and second portions of the panel member. The panel member may be configured as a floor panel of a vehicle.

Abstract: A process for making a solid component out of recycled powder coat is provided. The process can include providing a powder coat material and providing a second material. Thereafter, the powder coat and the second material are mixed to produce a powder coat-second material mixture. The powder coal-second material mixture is processed in order to produce a polymer containing precursor. The processing can include granulating or densifying the powder coat-second material mixture. After the precursor has been produced, it can be placed within a molding machine and a solid component is molded. The molding machine can be an injection molding machine, an extrusion molding machine or a blow molding machine.

Abstract: The present invention uses a high-gain observer which contains the discrete-time arithmetic expressions derived from a mathematical model of an injection and pressure application mechanism in an electric-motor driven injection molding machine consisting of state equations and outputs an estimate of injection pressure, which is one of the state variables of the above state equations, by using a screw position signal and a servomotor current demand signal or actual motor current signal as inputs. The high-gain observer obtains the exact injection pressure estimate with very small time-lag without using a pressure detector. Thus the estimate of injection pressure fed by the high-gain observer can be adopted as a feedback signal of actual injection pressure for controlling injection pressure.

Abstract: The present invention provides a method for producing an injection molded panel member having a first portion, a second portion, and an appearance surface portion. The method includes placing the appearance surface portion of the panel member into a mold cavity. The mold cavity preferably includes a first chamber adapted to form the first portion of the panel member, and a second chamber adapted to form the second portion of the panel member. After the appearance surface portion of the panel member is inserted into the mold, molten plastic material and pressurized gas are injected into the first chamber of the mold cavity. After the molten plastic material is injected into the first chamber of the mold, molten plastic material is injected into the second chamber of the mold cavity. The molten plastic is then cooled until it solidifies. After the molten plastic is sufficiently cooled, the pressurized gas is vented and the panel member is removed from the mold.

Abstract: A method and system for controlling the temperature of a fluid cooled high temperature injection mold having fluid channels formed therein. A high temperature injection mold has an operating temperature above the boiling point of water. A flow of either elevated pressure or low pressure cooling water is passed through the fluid channels in the high temperature injection mold for a limited duration during the molding cycle to thereby reduce the temperature of the injection mold to a desired level. Elevated pressure cooling water is elevated to a pressure level such that the cooling water will remain in a liquid state while passing through the fluid channels. Low pressure cooling water is at a pressure level such that the cooling water enters the fluid channels in a liquid state and transitions to a vapor state within the fluid channels.
