The amorphous alloy golf club head is integrally casted from an amorphous metal material, and includes a neck, a hitting panel, a peripheral wall, a cushion block and an adjusting member. The neck is configured for combination with a club; the hitting panel is connected to the bottom of the neck; the peripheral wall is located on a rear surface of the hitting panel, the peripheral wall forms a rear concave cavity with the hitting panel; the cushion block is embedded in the peripheral wall to reduce the casting thickness of the peripheral wall, and provided with a plurality of pillars thereon, wherein one end of each pillar is fixedly connected to the cushion block body, and the other end of the pillar has an exposed surface or exposed section not covered by the peripheral wall; and the adjusting member is matingly connected to the pillar.

A ball joint assembly for a vehicle includes a mounting part including an inner circumference part forming a hole in a vertical direction; a ball stud including a ball and a stud extending from the ball; a bearing coupled to surround the ball and disposed in the hole; and an insert molding part for filling the space of the hole formed between the inner circumference part and the outer surface of the bearing. The inner circumference part includes at least one upper protruding part protruding from an upper area thereof in a direction toward a central axis of the hole and at least one lower protruding part protruding from a lower area thereof in a direction toward the central axis.

A foundry casting system and process employs an inert gas delivery and recovery system for casting parts which results in cast parts having improved metalurgical characteristics. The system may be employed in sand, die casting, semi-permanent and permanent casting environments. Pressurized inert gas may be diffused into the mold before, during and after the metal pouring step. The resulting casting is free from oxides and dissolved hydrogen gas as they are removed from the mold cavity. This results in higher quality castings as well as increased production output due to faster cooling cycles.

A die casting machine with a die casting mold produces metal die cast parts. The die casting machine has a first machine shield, to which a first mold half of the die casting mold is secured, and a second machine shield, to which a second mold half of the die casting mold is secured. In order to compensate for the deflection of the machine shields, an intermediate plate which has at least two temperature-controlling devices that can be used to generate a temperature difference leading to the curving of the intermediate plate is arranged between the first machine shield and the first mold half and/or between the second machine shield and the second mold half.

A casting apparatus for manufacturing a cast product from molten metal includes a molten metal and a cooling portion. The molten metal contacts a surface for contact with the molten metal. The cooling portion forms a cooling flow passage. The cooling flow passage is configured to cool the molten metal contacting surface. At least a part of an inner surface of the cooling flow passage is constituted of a welding portion formed by welding, the welding portion sealing the cooling flow passage. The welding portion is constituted such that an exposure to the molten metal becomes equal to or less than a predetermined ratio with respect to an area of the welding portion constituting the inner surface of the cooling flow passage.

There is provided a method of producing a casing configured such that adjacent surfaces of the casing are maintained to be perpendicular to each other. A method of producing a casing includes: a first part forming step of forming a first part by pouring molten metal into a cavity formed inside a first die including a first die portion and a second die portion, the cavity corresponding to the first part, the first part including two plate portions connected to each other such that an angle between main surfaces of the two plate portions of the first part becomes 90, the two main surfaces of the two plate portions of the first part being formed by only one of the first die portion and the second die portion; and a second part forming step of forming a second part by pouring the molten metal into a cavity formed inside a second die including a third die portion and a fourth die portion, the cavity corresponding to the second part, the second part including two plate portions connected to each other such that an angle between main surfaces of the two plate portions of the second part becomes 90, the two main surfaces of the two plate portions of the second part being formed by only one of the third die portion and the fourth die portion.

A molding apparatus for obtaining an annular molded article has a fixed die D1 and a movable die D2 capable of forming an annular cavity C. A first block B1 and a second block B2 are formed inside the cavity C in the fixed and movable dies D1 and D2. The blocks form a flow channel R communicating with the cavity C. Thus, gas generated in the cavity C and a molten metal can flow in the flow channel R. A discharge hole B2b is formed in the second block B2 to discharge the gas flowing in the flow channel R to the outside. A forming surface of the flow channel R, in the first and second blocks B1 and B2, is formed in an outer circumferential shape following an inner circumferential shape of the cavity C.
