A method for manufacturing three-dimensional items with flexible walls is provided, by method of a mold and counter-mold between which a volume corresponding to that of the item to be obtained is delimited. The item is made up of laminar parts which are mounted on a template that is fixed to the inner surface of the mold. The laminar parts are joined to one another by means of a material which is injected in molten state through a network of conduits delimited between the counter-mold, template and the facing edges of adjacent laminar parts. The template is made of an elastically deformable material and has a three-dimensional configuration.

The invention relates to a manufacturing process for a reinforced conveyor belt and product thereby obtained comprising a plurality of plastic modules wherein each module comprises at least one opening that houses a roller and is configured to rotate with respect to a shaft, which consists of a metal tube able to be filled with plastic material; and which comprises the stages of (i) inserting the shaft in an injection mold for a plastic module in the region corresponding to the opening; and (ii) a single stage of injecting the plastic module such that said injected plastic fills the inside of the shafts forming a single assembly or structure with the body of the module.

A metal component has a shape including a flat plate-shaped part, and the flat plate-shaped part has a through-hole formed therein. A resin component has a shape including a covering part that covers a surface of the flat plate-shaped part, and the covering part has a surface in which a gate mark is present. The through-hole formed in the flat plate-shaped part of the metal component is located opposite to the gate mark. The resin component has a filler part with which the through-hole is filled.

An improved golf club head is provided having a striking face portion, a topline, a heel portion adapted to receive a shaft, a toe portion, and a sole. The improved golf club head includes port holes extending from one or more cavities to allow insertion of a polymer and metal shot into the golf club head. The insertion of a polymer and metal shot facilitates increasing weight and/or biasing weight distribution of the golf club head. The improved golf club head may be manufactured by forging the main body of the golf club head, machining a recess into the main body, and attaching an insert in the recess. The recess forms a cavity and allows a port hole to facilitate insertion of the polymer and metal shot into the golf club head. After insertion, the polymer is cured to form the golf club head.

A metallic unpainted injection molding for a vehicle is disclosed. The metallic unpainted injection molding for a vehicle is molded by injecting metallic resins into a molding part inside an injection mold through a plurality of gates to be molded, wherein at least a groove line is molded in a boundary section where metallic resins meet each other in the molding part.

A method of manufacturing a load structure may include forming a panel having a first side and a second side, clearing a fill passage through the panel, providing a tool having a first tool portion, a second tool portion, and a cavity disposed between the first and second tool portions, connecting a fill busing to the tool, the fill bushing includes a flange, disposing the panel within the cavity, disposing the fill bushing within the fill passage, connecting an injection gun to the fill bushing, and injecting a material through the fill busing and the fill passage such that one of the first side or the second side of the panel is at least partially covered with the material, the fill bushing is arranged within the fill passage to block the coating from contacting the other one of the first side or the second side.

The manufacturing method of a motor core includes attaching an ID code to a stack of blanked members in which a magnet insertion hole to fill with a resin material is formed, the ID code containing information in accordance with a type of the stack, reading the information from the ID code which is attached to the stack, and setting a mold condition based on the information read from the ID code. The mold condition includes at least one type of condition including: the resin material to be injected to the magnet insertion hole, an injection amount of the resin material, and a discharge position of the resin material. A mold device is controlled to inject the resin material to the magnet insertion hole in accordance with the mold condition.

A surgical instrument including a handle portion, a body portion, a movable handle, a tool assembly, a drive beam and a closure apparatus is disclosed. At least one of the closure apparatus and a contact surface of the tool assembly include a plastic surface. The body portion extends distally from the handle portion. The movable handle is located on the handle portion and is in mechanical cooperation with a drive member. The tool assembly includes an anvil, a cartridge assembly and a contact surface. The drive beam includes a proximal engagement portion and is configured to engage a portion of the drive member. The closure apparatus is configured to engage the contact surface of the tool assembly. At least a partial actuation of the movable handle moves the closure apparatus distally into engagement with the contact surface to approximate the anvil and the cartridge assembly.

An apparatus is configured to be positioned between a boss and a shell of a pressure vessel. The boss includes a bore therethrough, and the bore has a longitudinal axis. The apparatus includes an annular body and a gas permeable feature. The annular body includes an inner surface configured to abut the boss and an outer surface configured to abut the shell. The annular body has opposite first and second ends relative to the longitudinal axis. The gas permeable feature is provided on the inner surface and extends at least from the first end to the second end. The disclosure also describes a pressure vessel including a shell, and boss, and an apparatus positioned between the boss and the shell. A method for forming a pressure vessel includes mounting a boss on a mandrel, positioning an annular fitting about a neck of the boss, forming a liner, and forming an outer shell.

Methods and apparatus for applying internal features or complex mechanical structures to a surface of a metal part are disclosed. According to one aspect of the present invention, a method for creating an assembly that includes a substrate and a molded piece involves obtaining the substrate, and forming at least one binding feature on a surface of the substrate. The method also includes molding on a surface of the binding feature and the surface of the substrate. Molding on the surface of the binding feature and the surface of the substrate mechanically binds the molded piece to the substrate.
