A resin impregnation measurement device includes a jig and a resin impregnation sensor. The jig is formed into an inner surface shape of a protrusion of a stringer. The jig includes outer surfaces including a facing surface that is to face an inner surface of the protrusion. The resin impregnation sensor is disposed on the facing surface of the jig.

The present invention provides an imprint apparatus including a supply device including discharge ports which discharge a imprint material, and configured to supply the imprint material onto a substrate via the discharge ports, and a controller configured to cause, if there is a defective discharge port of the discharge ports, the supply device to discharge the imprint material from another discharge port, different from the defective discharge port, of the discharge ports, wherein a mold for the molding includes a line pattern, and the controller is configured to control the supply device such that an interval between supply positions of the imprint material do not become larger in a direction orthogonal to a direction along the line pattern than that before change from the defective discharge port to the other discharge port.

A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.

A modified compression moulding arrangement where the compression moulding tool has been modified to allow for the use of pre-impregnated pre-form sheets in order to produce class A automotive structural parts in high volume. The pre-impregnated pre-form has continuous un-chopped fibers that extend across an entire length of the pre-impregnated pre-form. The pre-impregnated pre-form is then placed in an open compression moulding tool that has a bottom half and a top half that are movable between an open position and a closed position. When the mould tool is in the closed position, the top half and bottom half create a forming cavity that is defined by a forming surface of the top half and a forming surface of the bottom half. The forming surface of the bottom half has a boundary defined by a run-off edge and an upshear that is necessary for forming a class A structural automotive component using pre-impregnated pre-form material.

A press molding apparatus includes two dies and press-molds a heated stampable sheet into a predetermined shape by using the two dies. The press molding apparatus includes a movable core provided in at least one of the two dies. The movable core is disposed at an inward side of an edge portion of a cavity. When receiving a pressure greater than or equal to a predetermined value, the movable core moves in such a direction that the cavity increases in volume.
