A molten magnesium material is filled into a product section of a die. The molten magnesium material is cooled and solidified in the die, so that a molded product is formed. Subsequently, a thread-shaped pin is rotated, so that a female-thread forming section is drawn from the female-thread section of the molded product while the female-thread forming section is rotated. Thus, the female-thread section can be formed when the molded product is formed. A magnesium-alloy material is not apt to stick to a steel material used in the die compared with an aluminum-alloy material, so that the female-thread section can be steadily formed.

A front-end module, including a heat exchanger including a radiator and a condenser integrated with each other, brackets, etc. and having a dual function as a strength member for the vehicle body, is mounted on an automotive vehicle. As a result, the front end panel is eliminated, and a simple structure is provided in which the parts which can be assembled on the front end of the vehicle, including the radiator, the condenser, headlights, a hood lock, a horn and sensors, can be assembled on the vehicle.

A first compact ( ) is molded by injection according to the MIM method in which a molding material composed of a mixture of metal powder and a binder is injected into a die for molding, after which a second compact ( ) is molded by injection in close contact with the joining surface ( ) of the first compact ( ) thereby to fabricate a metal composite compact ( ). The second compact ( ) is molded by injection by making it flow and fill a die ( ) in such a manner as to obtain a flow component (R) in the direction parallel to the joining surface ( ) of the first compact ( ) on the same joining surface ( ). In a method according to another embodiment, cavity surfaces ( ) formed on a reference die ( ) and a first replacement die ( ), respectively, are placed in opposed relation to each other thereby to form a first cavity ( ), in which the first compact ( ) is molded by injection. Then, while leaving the first compact ( ) in the cavity surface ( ) of the reference die ( ), only the first replacement die ( ) is replaced by a second replacement die ( ) having a cavity surface ( ) of a different shape thereby to form a second cavity ( ), into which the second compact ( ) is molded by injection.

A method of producing an insert-molding product in which an insert product is covered with a synthetic resin by arranging the insert product in a cavity of a mold is provided. The method includes holding the insert product by a holding pin, pouring a molten synthetic resin into the cavity, and retracting the holding pin. At least one moving pin is provided adjacent the holding pin. After the cavity is filled with the synthetic resin, the holding pin is retracted and the at least one moving pin is moved to extrude and introduce the synthetic resin into a space where the holding pin used to be positioned prior to its retraction from the cavity.

In a rotational phase adjusting apparatus which may be used for controlling opening/closing timings of intake and exhaust valves of an internal combustion engine, one side wall of a housing is fixed to one of a driving member and a driven member, while the other side wall of the housing is made integrally with a circumferential wall of the housing. A seal made of a material less harder than the housing is provided between the housing and a vane. The housing is made of an aluminum while the seal is made of a PPS resin mixed with an inorganic filler. The inorganic filler is harder than the PPS resin but less harder than the housing to reduce wear of the housing.
