A domer station having a domer assembly, a housing assembly, and a stacked piston assembly is provided. The domer assembly is movably disposed within a domer body passage located in the housing assembly and structured to move between a forward, first position and a retracted, second position. The stacked piston assembly includes a plurality of pistons, preferably three pistons, disposed in series and a pressure supply. The pistons are disposed behind the domer in pressure chambers. The pistons have a constant pressure applied thereto and are biased towards the domer. The pistons are, however, each restrained by a stop and do not contact, or operatively engage, the domer when the domer is in the domer first position.

Dental crowns and methods of making the same. The dental crown may include a metal shell shaped to cover a portion of a tooth of a patient; a coating retention metal layer diffusion bonded to the metal shell, wherein an interface between the coating retention layer and the metal shell comprises a plurality of interstitial regions; and a composition on the coating retention layer and within the plurality of the interstitial regions to bond the coating composition to the metal shell.

A method of and an apparatus for manufacturing a housing is disclosed. The housing to be manufactured has a sleeve-shaped housing wall extending about a longitudinal axis of the housing and a cover disposed inside the housing wall transverse to the longitudinal axis at a predetermined position between longitudinal ends of the housing wall. The method comprises providing a precursor of the housing, in which the cover is formed integrally with the housing wall and is arranged at one of the longitudinal ends of the housing wall, further separating the cover from the housing wall and displacing the cover relative to the housing wall in the direction of the longitudinal axis from the one longitudinal end into the predetermined position.

Provided are a press formed component that does not easily cause wrinkling on a vertical wall portion of a curved portion in a component shape having an L-shape, a T-shape, or the like when viewed in a plan view and a method for manufacturing the same. A press formed component includes a top sheet portion, a vertical wall portion continuous to the top sheet portion, and a flange portion and also includes a curved portion in which when viewed in a plan view, at least a part of a boundary portion between the top sheet portion and the vertical wall portion is displaced to the vertical wall portion side and curved concavely toward a longitudinal direction. In a cross-sectional shape of the curved portion, an inclination angle θ [deg] of the vertical wall portion with respect to the top sheet portion satisfies the following expression: (1−sin θ)/cos θ>0.95.

Provided are an integrated connector and a heat exchanger including the same, which may prevent assembly defects and leaks of a heat exchanger because the connector may be manufactured with precise dimensions, and is easy to manufacture, by integrally forming the connector that connects and firmly couples a header tank and a gas-liquid separator so that a heat exchanger medium communicates in the heat exchanger such as a condenser, in which the integrated connector is formed by molding a first pipe portion inserted into a hole of the header tank, a first flange portion in surface contact with an outer surface of the header tank, a second pipe portion inserted into a hole of the gas-liquid separator, and a second flange portion in surface contact with an outer surface of the gas-liquid separator so as to be connected to one another and have an interior communicating with one another.

A method for forming a semi-finished product is disclosed, wherein the semi-finished product is provided in a provision step and, in a solid-stock forming step, a forming region of the semi-finished product is formed such that a thickness of the deformed forming region increases continuously toward one margin of the semi-finished product.

A press forming method includes: a first forming step of press-forming a preformed part including: a top portion and flange portions having same shapes as a top portion and a flange portions in a target shape of a press-formed product; and side wall portions having projecting chevron shape in a cross-section in a press-forming direction as compared with side wall portions; and a second forming step of press-forming the preformed part into the target shape. Each side wall portions includes: a side wall portion adjacent to top connecting to the top portion; a side wall portion adjacent to flange connecting to the flange; and a bent portion between the side wall portion adjacent to top and the side wall portion adjacent to flange. An angle on an acute side formed by the side wall portion adjacent to top and a horizontal plane decreases toward an end portion from a center.
