A method and system for feeding a lubricating or releasing agent from a dosing station to one or more pressing tools arranged in a pressing chamber of a tablet press. The tablet press is configured with a feed pipe for feeding the lubricating or release agent from the dosing station to the one or more pressing tools of a pressing chamber of the tablet press and the feed pipe is configured with a shut-off valve disposed in-line with the feed pip for controlling the flow of the lubricating or release agent to the pressing chamber. The method comprises the steps of: producing a negative pressure with respect to the surroundings of the pressing chamber of the tablet press, measuring a pressure in one of the feed pipe and the pressing chamber, and issuing a signal indicative of the measured pressure and issuing an enable signal to open a valve in response to the pressure signal.

A door panel manufacturing process is provided by constructing a high load conveyor line capable of controlling speed and duration, subsequently placing a finished door panel mold on the high load conveyor line. The conveyor line can be used to control a shifting speed and duration, and a de-molding agent can be sprayed inside the door panel mold, followed by spraying a high-density foam resin to form a shell. The door panel mold further has a framework or a reinforcement member mounted therein, and a low-density foam resin is injected; after the foam resin is formed and cooled, the door panel made of foam resin is completed. The process solve issues of high defective rate and insufficient surface strength associated with the conventional foam door panel, and is capable of significantly reducing the electricity required as well as reducing logging of woods, thereby realizing environmental protection.

Systems and methods are provided for enhancement of vacuum bagging processes for a composite part. One system includes dispensers configured to dispense materials onto a forming tool for a composite part, and a controller. The controller is able to identify a location for placing the composite part on the tool, and to direct the dispensers to lay up a laminate of constituent material for the composite part at the location. The controller is also able to direct the dispensers to spray vacuum bag material atop the laminate to form a vacuum bag that covers the laminate.

A molding process of a co-cured short-fiber resin-based damping composite material and a molding part. Different from a traditional centrifugal processing process of a thin-walled tube of a resin-based composite material, the process uses raw materials including three kinds of materials with different densities and including two kinds of short-fiber epoxy resin with different densities and a damping material. During centrifugal molding, the three kinds of materials are made into fluids to be respectively injected at a uniform speed in three times according to the sizes of the densities. Layering is performed by using different centrifugal forces applied to the three kinds of materials. Co-curing is performed according to a resin curing process after the three kinds of materials are stably distributed, and a tubular thin-walled part of the embedded co-cured short-fiber resin-based damping composite material with a uniform wall thickness is obtained.
