A conveyance device includes a plurality of holding mechanisms and one or more pressing mechanisms, the holding mechanisms each include a holder that holds a molding material and a holder movement mechanism that moves the holder, and the pressing mechanisms each include a pusher that comes into contact with and pushes the molding material and a pusher movement mechanism that moves the pusher.

Conveyance device and conveyance head

To provide a method of manufacturing a press molding by molding a molding material comprising reinforced fibers and a thermoplastic resin by a cold press method. The method of manufacturing a press molding comprising reinforced fibers and a thermoplastic resin, includes the steps of:

Method of manufacturing a press molding

An injection apparatus including a plasticizing unit () that plasticizes a raw material resin and an injection unit () that injects a plasticized molten resin. The plasticizing unit includes a heating cylinder () having a foaming gas injection valve and a screw () provided inside the heating cylinder. The rotation and advance and retreat movements of the screw are controlled such that a raw material resin is plasticized by the screw and a foaming gas injected from a foaming gas injection valve is dissolved in the plasticized molten resin. After the screw retreats to a prescribed position according as the molten resin accumulates in the front end side of the heating cylinder by the screw that is rotating, the screw advances with rotating to cause the molten resin which has been accumulated in the front end side of the heating cylinder to be transferred to the injection unit.

Method for manufacturing foamable injection molding and injection device therefor

A plasticizing process in which a molten resin that has been plasticized and dissolved in a foaming gas is sent to the front end side of a heating cylinder () by means of a screw () that rotates in a heating cylinder (), and the screw () retreats according as the molten resin accumulates in the front end side of the heating cylinder (); a transfer process in which the screw () is advanced with rotating and transfers the molten resin accumulated in the front end side of the heating cylinder () from a plasticizing unit () to an injection unit (), and an injection process in which the molten resin is injected from the injection unit () are conducted and repeated to produce a foamable injection molded product.
