A resin molding method includes a first molding step of molding a first molded part and a second molded part in a mold and a second molding step of joining the first molded part and the second molded part. In the first molding step, the second molded part is formed by injecting resin into an area where a first core movable in the first direction and a second core movable in a second direction are engaged. In the second molding step, the second molded part is joined to the first molded part by injecting the resin while the first core is in contact with the second molded part and the second core is removed from the second molded part. Areas where the first core and the second core are located in the first molding step become hollow areas connected to each other and part of ends of the first core in the first direction is not in contact with the second core.

Reusable cartridges allow the time consuming resin preparation and processing steps to occur offline and not affect the cycling time of the injector. Cartridges also greatly simplify the operation of RTM injectors as preparation simply consists of loading a warmed ready-to-use resin cartridge and performing the injection.

A manufacturing method of a cartridge that is detachably mountable to an apparatus main assembly of an image forming apparatus. The manufacturing method includes a step of integrally molding a cartridge electrode with a frame in a manner such that a mold is contacted to the frame to form a space including a first portion for forming a first contact portion, a second portion for forming a second contact portion, and a connecting portion branching from an injection portion into the first portion and the second portion, and electroconductive resin is injected into the space.

A plastic product, for example a cartridge, is made of plastic material which has a ratio of at least 30 wt.-% of PCR (Post Consumer Recycled) material. A method for producing a plastic product using an injection molding process includes the following steps: (a) providing a partially recycled plastic material comprising a ratio of at least 30 wt.-% of PCR material; (b) liquefying the plastic material; (c) injecting the liquid plastic material into a cavity of a mold; and (d) demolding the product after cooling.

A method of manufacturing a flow path member which forms a flow path such that a concave portion provided on a first surface of a first member is covered with a second surface of a second member, the method includes introducing a part of a fused director to an inner side of the concave portion when viewed from a direction in which the first member and the second member are laminated; and fixing the first member and the second member by curing the fused director in a state where the concave portion is covered with the second surface to form a flow path.

A system and method for processing objects having contaminating particles includes the steps of shredding the objects in a shredding chamber to form a plurality of shredded fragments, wherein the shredding chamber is arranged to be substantially combustion resistant, and removing the contaminating particles from the plurality of shredded fragments.

Reusable cartridges allow the time consuming resin preparation and processing steps to occur offline and not affect the cycling time of the injector. Cartridges also greatly simplify the operation of RTM injectors as preparation simply consists of loading a warmed ready-to-use resin cartridge and performing the injection.

A molding apparatus is used, the apparatus including a mold made up of a first mold, a second mold opposite the first mold, and an intermediate mold disposed between the first mold and the second mold. The apparatus further includes a support member configured to support the intermediate mold, and an injection mechanism configured to inject molten resin. The support member includes a rotating mechanism. The intermediate mold is mounted on the rotating mechanism such as to rotate coaxially with the rotation axis of the rotating mechanism.

There is used a container which includes a first member which serves as a lid portion, a second member which serves as a container portion, and resin with which a flow path, which is formed between the first member and the second member when the first member and the second member come into contact with each other, is filled, the resin bonds the first member and the second member to each other by reaching a filling target position after flowing in from an inflow opening to the flow path, and an opening portion exposed to an exterior of the container is provided at a position where the resin having flowed in from the inflow opening flows out beyond the filling target position in the flow path.

A mold includes a rotatable portion, a frame portion, a first and second portion, and a production unit. The rotatable portion has a plurality of surfaces and a plurality of forming portions. The plurality of surfaces is each provided with one of the plurality of forming portions, each having the same shape. The frame portion rotatably supports the rotatable portion. The first portion defines a cavity by coming into contact with one surface of the plurality of surfaces by clamping the mold. The second portion comes into contact with another surface of the plurality of surfaces different from the one surface by clamping the mold. The production unit attached to the frame portion.
