A mold assembly for forming a component exhibiting a sealed interior, including providing first and second mold halves, forming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed.

A hydraulic control device for a vehicle drive device that includes a first layer having a first opposing surface, a first groove formed in the first opposing surface, and a first bonding formed on the first opposing surface and surrounding the first groove; and a second layer having a second opposing surface facing the first opposing surface, a second groove facing the first groove and formed in the second opposing surface, and a second bonding facing the first bonding, surrounding the second groove, and bonded to the first bonding, the second opposing surface being placed on, and bonded to, the first opposing surface, so that the first groove and the second groove form a first oil passage.

Food container including: an external container composed of a material comprising a first plastic material, an internal container composed of a material comprising a second plastic material, said internal container being arranged inside the external container and being welded to the external container so as to form a sealing cavity between the internal container and the external container, said cavity including gas, characterized in that at least a portion of said internal container is resilient and configured to deform under expansion of the gas contained inside the cavity.

A molded resin article and a method of manufacturing a molded resin article that suppresses generation of portions of reduced bonding strength while suppressing separation at the interface between a bond portion (secondary molding resin) on the one hand and a first body and a second body on the other. The molded resin article has a first contact surface formed perpendicular to the main surface of the first body and contacting the second body, a second contact surface formed perpendicular to the main surface of the second body and contacting the first body, and a bond portion bonding together the first body and the second body, formed by injecting molten resin into a resin channel formed by contacting the first contact surface against the second body and contacting the second contact surface against the first body and solidifying the molten resin.

A method includes a first molding process and a second molding process performed repeatedly. The first molding process includes injecting resin into a first pair of molds, in which a first pair of divided pieces is formed and which is fitted together without an inner mold, to couple the first pair of divided pieces to form a first hollow article at an injection station. The second molding process includes (i) injecting resin into a third pair of molds, which is fitted together with one inner mold interposed therebetween, to mold a third pair of divided pieces at the injection station, (ii) taking out the first hollow article from the first pair of molds at a removing station, and (iii) removing another inner mold from a second pair of molds while leaving a second pair of divided pieces between the second pair of molds at the setup station.

A forming device of a base material and a skin layer may include a lower mold having an upper surface on which a first forming surface is formed and including a vacuum path formed inwardly from the first forming surface to be connected to the vacuum chamber; an upper mold disposed to be movable upward and downward by a press device and having a lower surface on which a second forming surface is formed to correspond to the first forming surface of the lower mold; a pressurizing member disposed at the outside of the second forming surface of the upper mold to be movable toward the upper surface of the lower mold; and a pressurizing cylinder pushing the pressurizing member toward the upper surface of the lower mold to closely adhere the skin layer injected between the upper mold and the lower mold to the upper surface of the lower mold.

A method of producing an assembled product includes a first step of clamping a mold including a first unit and a second unit, a second step of forming the plurality of parts by injecting molten resin into each of a plurality of cavities, a third step of opening the mold, and a fourth step of respectively opposing the plurality of parts held by the first unit in the third step to corresponding assembling portions of the second unit. The first through fourth steps are repetitively performed, and in the first step, the plurality of parts held by the first unit are supplied to the corresponding assembling portions, and the plurality of cavities are defined by first forming portions of the first unit and second forming portions of the second unit.

Provided is a method for manufacturing a liquid-ejecting head whereby in die slide injection molding it is possible to stably inject resin in secondary molding without damaging the shapes of parts that were formed in primary molding. In order for that, in the connecting section in which a convex section of a cover member is inserted into an opening of a liquid-supply member, the closest distance to the opening in the area where secondary resin is injected is made larger than the gap between the opening and the convex section. As a result, the resin is prevented from flowing into a liquid path during the secondary molding.

Methods and systems are disclosed for internal shock isolation in an information handling system. The method includes directing a tool to mold an outer frame of an information handling system, and directing the tool to mold an inner frame of the information handling system. The inner frame has a perimeter less than the perimeter of the outer frame. The method further includes directing the tool to construct a first plurality of braces in an interspatial area. The interspatial area is between the perimeter of the inner frame and the perimeter of the outer frame.
