According to one embodiment, a mold device includes a first mold. The first mold includes a substrate clamping surface, a cavity, a suction part, a vent, first and second intermediate cavities and an opening/closing part. The substrate clamping surface contacts a surface of a processing substrate. The cavity is recessed from the substrate clamping surface. The suction part is recessed from the substrate clamping surface. The vent is provided on a path between the cavity and the suction part, and is recessed from the substrate clamping surface to a vent depth. The first intermediate cavity is provided between the vent and the suction part, and is recessed from the substrate clamping surface. The second intermediate cavity is provided between the first intermediate cavity and the suction part, and is recessed from the substrate clamping surface to a second intermediate cavity depth. The opening/closing part opens and closes the path.

Provided is a forming mold for a pressure container liner including a female serration on an upper face of a top portion. The forming mold includes an insert including a recessed-projecting portion by which the female serration is to be formed. The insert includes a lower layer and an upper layer divided from each other in the up-down direction. Bolt holes are formed in respective radial central parts of the upper layer and the lower layer. Gaps on contacting faces between the upper layer and the lower layer are set to a size that allows gas to pass through the gaps but does not allow nylon resin to pass through the gaps. An air-discharge passage via which a vicinal area of the recessed-projecting portion is connected to the bolt holes is formed on the contacting faces.

There is provided an injection mold system and a method for injection molding to produce a three-dimensional object. The system including: one or more extruders each adapted to receive one or more cartridges, the one or more cartridges containing extrudable material; an injection nozzle dimensioned to be positioned into an injection inlet of a mold; tubing each connecting one of the cartridges to the injection nozzle; and one or more controllers configured to control flow of the extrudable material from the one or more extruders to the injection nozzle to fill at least a portion of the interior chamber with the extrudable material to produce the three-dimensional object.

A pin for a mold includes a first portion extending from a first end of the pin. The first portion of the pin includes an outer shell that has a first material density that is gas-impervious. The first portion of the pin also includes an inner core extending form the first end that includes a second material density that is gas permeable.

A mold insert and an injection-molding machine including the mold insert. The mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided.
